Explain how the example of the earthworm illustrates negative phototaxis.
Reading
Negative Phototaxis While many organisms need light to survive, certain animals that live in dark environments need to avoid light because it threatens their survival. When exposed to light from the Sun oranother source, these animals move away from the light, seeking darkness. This movement pattern is called negative phototaxis.Negative phototaxis allows animals to avoid thedangerous effects of being exposed to light. In order to be able to move away from light, these animals often have special physical features that allow them to sense the presence of light,since they live in the dark and may not have fully developed vision.

Professor: OK, so as an example, let’s look at earthworms. As their name suggests of course, earthworms spend most their time living underground. And this underground environment is dark and moist which is perfect for earthworms. They need to keep their skin moist because they absorb oxygen from the surrounding soil through the surface of their skin. They actually breathe through their skin. So, if an earthworm ended up above the ground, exposed to the sunlight, it would need to escape, get out of the sunlight. Since the rays of the sun would eventually cause its skin to dry out. And with dry skin, the worm wouldn’t be able to breathe, they would die. But the thing is earthworms don’t have eyes, they are unable to see things the way many other animals can, but when they’re digging tunnels through the earth, they know, if they accidentally dug tunnel to the surface. Because they have special cells on the outside of the bodies that are sensitive to sunlight. So, if a worm digs a tunnel that leads toward the open air and sunlight, these cells detect the light and the worm reacts by turning around and going the other way, tunneling deeper underground until its cells no longer detect sunlight. This way the worm manages to stay underground where, its skin can stay moist.

The negative for the taxes Negative phototaxis is when some animals say a voice on the island living the darkness in order animals, like earthworms, avoid light to survive. This is an example of the earthworm. They Earthworms live on the ground underground because the underground area is this dark and moist environment is ideal for them; they actually breathe through their skin, which needs to stay moist. The moist underground area is good for this game because If they use come above ground and are exposed to sunlight, their skin can dry out, making it hard for them to breathe. So if they get out of the ground and explode to this sunlight, the skin will dry out Earthworms don’t have eyes, so they can’t see like many other animals do. However, they have special cells on their skin that can breathe. Also sense light. When they dig and accidentally reach the surface, these cells detect the sunlight, and the earthworm they don't have eyes. So when they dig they can sense the sunlight. So if they sense the sunlight they will turn around and dig in another direction deeper underground to avoid to get to the ground.light.
Richard
The professor in the lecture brought up mentioned a specific space type of animals that animal called the earthworm. Earthworms are called earthworm. Earthworm are animals creatures that live underground in a dark and a moid area. dark, moist areas. They breathing breathe and absorb oxygen through their skin. They need skin, which is why it's important for them to keep their skin moid moist and not let it dry out in order to survive. While out. Although they don't have eyes to detect whether see if they are exposed under the to sunlight, they have a special developed specialized cells on their bodies that help them to can detect sunlight light. When these cells sense sunlight, the earthworm reacts by turning around and escape from sunlight in time to keep their burrowing deeper underground, ensuring that its skin from drying out so they stays moist and it can survive.
George
In order to protect themselves, some animals will seek darkness and avoid light. And this light, a movement part part part part is called negative photograph, photo text. Some animals phototaxis. For example, earthworms live underground most of the time to stay away from light. They need to keep their skin moist to breathe, as they absorb oxygen through it. If they are exposed to light, their skin can dry out, which is dangerous for them. Earthworms don’t have eyes like many other animals, but they have special features for them to cells in their skin that can sense the pressure of light. And as a professor, took an example of earthworm. In most of time, earthworm living undergorm to protect themselves avoid light. They have to keep moisture to protect their skin. And So, if they expose dig a tunnel that leads to the light, it may cause them dry out surface and died. But earthworm don't have eyes. So detect sunlight, they have the sense of light depends on their special skin out of their body.will turn around and go deeper underground to stay safe and moist.
Wesley
So the So, negative photo-taxes phototaxis means that some animals avoid lights light to survive. And as Earthworms are a good example because they have, there are some have physical features that help them leaving underground, escaped stay underground and escape from sunlight, which can be dangerous for them. In the sunlight, otherwise they were bit dangerous. So in the Professor's professor's lecture, we can know learned that the animals are often leaving underground and the environment there is very black and do not have enough air. So the animals may make earthworms live in dark, moist environments where they need to keep their skin be moist. So when moist to breathe. When they expose the are exposed to sunlight, their skin risks drying out, which would prevent them from breathing. Since earthworms don't have the risk that being dried out so eyes, they cannot breathe. So they need to escape and they also do not have eyes. But when they begin to how they have the seals rely on special cells on their bodies that can detect light. If they dig a tunnel that leads to the sunlight. So even if they surface and detect the sunlight, the seals these cells make them turn around and go back underground, where their skin can react.stay moist.

The lecture talks about explains negative photo text that phototaxis, which is that when animals expose to the night, they will move away from night light to seeking seek darkness for darkness to avoid dangerous. In the last name, the their survival. The professor gave an the example about Earth's worm, they believe on the ground of earthworms, which live underground and then they took care of need to keep their skin moisture. When moist. If they expose are exposed to the sound, they will skip. When their skin dried out, they will skin moisture dry out, they will die. They also have no eyes. When they dig in holes, they have facial cells. It is another feature of their body. It will run around until deeper ground, sunlight, their skin can keep moisture. So this is dry out, and they could die. Earthworms do not have eyes, but they have special cells on their bodies that can sense light. If they accidentally dig a way tunnel that leads to the surface and detect sunlight, they design more products.will turn around and dig deeper into the ground to avoid the light. This behavior helps them stay underground, where their skin can remain moist.
Leon
The photo text means that term negative phototaxis refers to how some animals animals, like earthworms, need to avoid the sunlight to survive, because if survive. If they explode under the are exposed to sunlight, there will be their skin can dry out, making it hard for them to leave. And they often have some physical future that's not complete to vision. And the professor gave the example about the art form. This kind of animal often leaves the undergone and in order breathe. Earthworms live underground to keep their skin moist moist, and if they do not escape before the sunlight goes to there, so have special cells that can sense light. Even though they will explode. Flows under the sunlight and their skin will dry out, so they will become hard to breathe. And the second, the body do not don’t have a complete vision, but these cells help them detect when they can get that where are getting close to the sunlight goes surface. If they sense sunlight, they turn around and they do the deep under...dig deeper underground to stay safe and moist.
Cicily
The narrative for Tux is some pieces example of the earthworm illustrates negative phototaxis because these animals need to avoid and get away the sound night you light to survive. Earthworms live and underground in dark, moist environments, which is essential for keeping their skin moist. They absorb oxygen through their skin, so if they are exposed to sunlight, their skin can dry out, making it difficult for them to breathe. Although earthworms cannot see like other animals, they have special cells on their bodies that can sense light. If an earthworm accidentally digs up to the spiritual features surface and detects sunlight, it will turn around and tunnel deeper into the ground to avoid the dangerous and there light. This behavior is a sample clear example of the earthworm. The earthworm has the spiritual features because the earthworms skeins if you stay on a sound night's environment this skeins will die quickly then we will die so they will usually get some food and having not in the dark environment and so this phenomena called the negative relaxphototaxis.
Steven
Also, plans Many organisms, including plants and animals animals, need some right light to survive, but some of them are upset. Some of them try some, like earthworms, need to avoid some right. it. This movement away from light is called negative foot attacks is phototaxis, which the professor giving example of the earthworms. used to explain how earthworms behave. Earthworms live underground, where it’s dark and moist, which is ideal for them. They spend a lot of time on the ground because it's a good place for them to start. They breath by breathe through their skin, so if they expose are exposed to the sunlight, their skin will be can dry out, and do a they could die. And Although earthworms don’t have eyes like many other animals, they have special features cells that they have no eyes. They can see like a normal animals, but they can sense sunlight. They can detect sunlight. light. If they found dig a tunnel that leads to the exposed surface and detect sunlight, they will turn around and tunnel deeper underground to deeper underground.stay where it’s dark and safe.

Lactyl phototech says it's Negative phototaxis is a movement pattern that will animal where animals exposed to the sunlight. They sunlight will avoid the light because it will straighten threatens their survives. And they are survival. These animals usually have some special phase cofatures physical features to help them to escape. And escape from the light. The professor gave an the example of earthworms. Earthworms live underground, where the environment is Earth's worm. Earth's worm living in the underground and this environment are usually very moist and dark. Their skin is also very dark. And Earth's worm have some special skin and this skin are very moist. Help moist, which helps them to breathe. And when When they are exposed to the sunlight, they will try to escape. And escape because if they love this gap, stay above ground for too long, they will try can dry out and they cannot breathe. But Earth's worm suffocate. Although earthworms don't have eyes. But eyes, they have special cells. They cells that can sense the light. And when When they detect the sunlight, they will have some react and they will go to deep by burrowing deeper underground.
Eric
The negative photo-textes Negative phototaxis is the insert when certain animals that live in the dark when they expose to the tide light of environments move away from light, like the sun or another source. Other animals will be go away from the light. So they have special features to let them live. In the last new window, there have animals named Arsorms. They almost other sources. For example, earthworms spend all the most of their time under the ground underground because they need to keep their skin moisture. They use the moist to breathe. If they are exposed to sunlight, their skin can dry out, and they won't be able to breathe and if the skin becomes dry, they will can breathe so they could die. So Earthworms don’t have eyes like many other animals, but they have an ice, how to special cells on their skin that can detect the light. Arsorms have special skin, can find the light. So if If they become dig a tunnel that leads to the surface, they will detect so surface and sense sunlight, they will turn to the under...around and go back underground where it’s dark and moist.
Selina
The negative photo taxes Negative phototaxis is the movement pattern that allows the animals to avoid the dangerous effect effects of exposed exposure to the light, which can help the animals live helps them survive in the dark and move away to the light. environments. The professor explained that some animals earthworms, for example, live on the ground to let their skin become underground where it is dark and moist, which is essential for their survival because they breathe through their skin can let them breathe. But if skin. If an earthworm comes to the skin surface and gets exposed to the sunlight, the its skin will dry out, and it won’t be dry out able to breathe. To avoid this, earthworms have special cells on their bodies that can detect light. When they dig and they can't breathe, so accidentally reach the skin will be dark. So surface, these cells sense the animals have a special skill light, prompting the worm to face turn around and tunnel deeper into the sunlight, which ground where it can stay moist. This behavior illustrates negative phototaxis as the cell can make earthworm moves away from the animals deeper on the ground, and their skin will be more moist. So this is the negative photo taxes the professor mentioned.light.
Alice
Negative phototaxis, which means when it explodes phototaxis refers to light from the sun or other source, these behavior of animals which live in the light, living dark, will that move away from the light and the sticking darkness, it can sources to avoid dangerous. And also danger. For example, earthworms live in the lecture, the professor mentioned the earth's warmth. dark, moist environments underground. When they expose accidentally come to the surface and are exposed to sunlight, they need to escape quickly because their skin can dry out, which would prevent them from breathing. Even though earthworms don’t have eyes like many other animals, they have special cells on their bodies that can detect light. If they sense sunlight while digging, they will escape from this and they drive out because they always live in dark, so they can only breathe in dark if they expose to sunlight for a long time and they can't die. And in another animal, if they meet sunlight, they just turn around and go back up the light.underground to stay safe and keep their skin moist.
Michael
The next hit photo text Negative phototaxis refers that when the animals detect the sunlight they build to escape how some animals, like earthworms, move away from sunlight to avoid or treat it for survival. They survive. Earthworms have some special physical features to allow that help them to detect the sunlight and the lectures professor gave us an example about Earthworm. The Earthworm needed to leave the animals underwound to keep the moist shirts and to brace them to survive. But light, even though they can't see anything like other animals. So they The professor explained that earthworms live underground, where it's dark and moist, which is essential for keeping their skin moist. If an earthworm accidentally digs up to the surface and is exposed to sunlight, it can harm them because their skin would dry out. To avoid this, earthworms have special cells on their bodies that sense sunlight. When these cells detect light, the special physical features about the cells. The cells earthworm reacts by turning around and digging deeper underground, where it can detect the sunlight stay moist and let them take action to move the underground when the cells do not detect the sunlight. They will keep them there and they can survive to brace to keep moisture.survive.

Nactivity photo taxi Negative phototaxis is a movement part of pattern that allows animals to avoid the dangerous facts effects of being exposed to light. Just like the example being by For example, as the professor about the Earth's world. The Earth's world is living in the mentioned, earthworms live underground and in order to keep moisture. And actually if stay moist. If they come above the ground ground, they will dry risk drying out and then they can't breathe. Finally they will die. However they don't being unable to breathe, which could lead to their death. Earthworms don’t have eyes so they can't see their position as like many other animals. However animals, but they have special shells cells on their body that can sense light. If an earthworm digs a tunnel that leads to the body surface. So if they fill the light they surface and detects light, it will turn into around and dig deeper underground to stay safe and to keep safe.maintain moisture.

In this lecture, it's we learned about the negative photographs. That's saying, some phototaxis, which is when certain animals or the plants living that live in the dark environments that avoid the sunlight than too survival. This semester is negative photographs that the animal will to survive. For example, earthworms are a great illustration of this concept. They move away from sunlight because exposure can harm them by drying out their skin, which is crucial for breathing. The professor explained that earthworms don't have eyes, but they have special cells on their bodies that can sense light. If they dig a tunnel and accidentally reach the sunlight that is for surface, these cells detect the purpose is sunlight, and the earthworm will turn around and go back underground to avoid dangerous. And the professor have examples that like some plants, they avoid the light. They avoid the lights, then leave the dark environments that to avoid them to die out. Dry out, if they die out, they will die. And the second really is that they can sell in the lights then to direct their ways stay moist and to avoid them to dry out and no longer the sunlight.safe.

negative photos Texas Negative phototaxis refers to the behavior of animals that was exposed to light from the sound or other another source this animals move away from light to seek darkness, which is crucial for their survival. The professor explains this using the light seeking darkness the professor gives us an example that some one of the animals species said earthworms. Earthworms live underground, where it does not when the they is dark and moist, which helps them keep their moisture skin moist for breathing. They don't have eyes, but they have special cells on their bodies that can sense light. If an earthworm accidentally digs up to prevent dryouts the surface and they use their encounters sunlight, these cells detect the light, and the worm quickly turns around to prevent dryouts and when they are get dig deeper back into the when darkness. This way, the sound gets to get into very intense their special cells can help them to keep moisture from the intense sunlight toearthworm avoids drying out and stays in a safe environment.

Negative photo taxes phototaxis is a the movement away from the sunlight and turn to the towards darkness. It can This behavior helps animals avoid the dangerous effect. effects of light exposure. The professor gave an the example of Earthworm, earthworms, which is a species living under the ground and living live underground in a moist environment. They absorb oxygen from the soil through their skin. If they accidentally get come above the ground, they will cause their skin to can dry out and they will finally die. They out, which can be fatal. Earthworms have a detector special cells on their skin that can detect sunlight when their skin has some negative detection. They sunlight. If they sense light, they will turn their direction around and dig deeper into the ground to try to back to the ground.stay safe.

Negative photo text phototaxis is an animal a behavior in animals that avoids the sound life helps them avoid light to avoid the dangerous or stay safe from predators. The animal will just Animals that exhibit this behavior often live in the dark. There are some physical features to help animals to do that. Here is an example of Earth's womb. Earthworm keeps dark environments. For example, earthworms keep their skin moist, moist, so that they can get oxygen and... oxygen to breathe. However, if the Earth's womb just explodes to the sound shy, their skin will just dry out and then they will die. But Earth's womb doesn't have eyes, moist so they can detect that whether they are in the sound shy. So they absorb oxygen and breathe. If an earthworm is exposed to sunlight, its skin can dry out, which would be dangerous and could lead to death. Earthworms don’t have a scale that eyes like many other animals, but they can still detect light. They have special cells on their bodies that there is sense sunlight. If they dig a sound shy. They tunnel that leads to the surface and detect light, they will turn around and go back underground to stay safe and keep their sound shy, they are just big two.skin moist.
Lauren
Some animals in order develop physical features to avoid the dangerous effects of light, they will develop some physical features to avoid the sunlight, and light because they don't have the good vision. The example used in from the conversation is the arseworm. Arseworm, they earthworm. Earthworms spend a lot of time underground, and they need to keep their skin needs to become moist. So if If they make them come above the ground, their skin can dry out, and they will dry out and then could die. However, the arseworm, they don't Earthworms don’t have eyes, so, but they know where the pollutions they need to go, because they go to stay safe. They have the spatial seal special cells on their bodies that can detect, let's help detect light, which helps them know when to detect, turn back and finally, dig deeper underground. This way, they can go to deeper place.stay in a moist environment and avoid the harmful sunlight.
Raymond
The reading passage introduced a series of talked about negative photo-tax about phototaxis, which is when certain animals leave a void of sunlights. They seeking darkness that they need to avoid the sunlight because it can be dangerous efforts of under the explosion of sunlight. for them. In the lecture, the professor said that give us an gave the example about earthworm. That earthworm spends of earthworms, which spend most of their time on their ground. underground where it's dark and moist. They must need to keep their skin moisture or moisture moist to life breathe, and if they come above ground into the sunlight will make sunlight, their skin can dry out, making it hard for them skin dry out and this will kiss them hardly to breathe and then they will die. So survive. Earthworms don't have eyes, but they have a special organ of cells in their skin. This organ skin that can attack sense light. If they accidentally dig their tunnels too close to the air surface and detect sunlight, they turn around and dig deeper into the sunlight ground to stay safe and then liquid turns.moist.
Jason
The negative photo text Negative phototaxis is a movement pattern that is exposed to light from the sun or another sources. This where an animal moves away from the light sources, seeking darkness. The professor in provided the lecture gave an example of what the animal was, when it was time leaving ground earthworms, which live underground where it's dark and leaving ground, it will make some action to make them warm. So they can expose the scheme moist. When an earthworm accidentally digs its tunnel to the sunlight surface and is exposed to sunlight, it needs to escape it. They want to get out the sunlight, but avoid drying out. Although earthworms don’t have eyes, they have no eyes or able special cells on their bodies that can sense light. If they detect sunlight, they react by turning around and tunneling deeper underground to see the things. So they use their ability to avoid dangerous effects from the sunlight. So move to the darkness stay moist and do you keep themselves?safe.
Meredith
The negative photo-taxes Negative phototaxis means that some animals animal species are trying try to avoid the expose of the exposure to sunlight because these will threaten it threatens their survival. And In the negative photo-taxes means that they will use some strategies to help them avoid the sunlight. An lecture, an example in the lecture is given about the Earth's womb. The Earth's womb are earthworms. Earthworms usually living live underground because where there is no without lights light and also moisture. And this can help the environment is moist. This helps them keep their skin moist, which is important for breathing. If an earthworm accidentally digs to keep the skin moisture and help them to breathe. So, when the Earth's womb are accidentally dig into the surface and they were trying surface, it will try to escape from the sunlight because it will make them can dry out and dry and dying. So, the Earth's womb die. Earthworms don’t have no eyes. They eyes, but they have seals. special cells on their bodies that can sense sunlight. These seals can cells help them detect light and turn around to sensitive the sunlight and help them to get go back underground, away from the sunlight.
Claire
Some of the animals that have been more animals, like earthworms, avoid the light that because it can be dangerous for them. They live underground where it is called the nati for the past. And in this area they chose to live in the ground daily dark and the vaccine must have a full of random not fishes. And the parés are given some examples about this. And most of ground dark skin, the skin, they moist. Earthworms need to use this keep their skin moist to breathe, since they actually breathe because through their skin. If they come up to the mask-capable surface and are exposed to sunlight, their skin are clear and dry. Actually, because they can dry out, which is harmful. Earthworms don't say the sunlight are here, it's really have eyes, so they just keep them spinning and moving fast and so they can breathe. And second, in this animal, special space animals didn't have the eyes. So the mask, can't see light like other animals. Instead, they have special cells on their skin that can sense light. If they dig up to the special space surface and sense light, they will turn around and go back down to save sunlight for other things, its dangers were not. So, on all this is some example stay safe and about the...moist underground.
Mason
Okay, the concept of negative photo-texas is phototaxis refers to how some animal species live a void avoid light in order to survive. So they can avoid dangerous. And the The professor gave us an the example about of the earthworm. So from the name we can tell As suggested by its name, the earthworm live lives underground, and very moist where the environment is very perfect dark and moist—perfect for them because it can keep them skin moisture. They use keeps their skin to moist. Earthworms breathe and through their skin, so they are very sensitive. The skin is very sensitive to sunlight. So they must have always They need to avoid sunlight because they will cause it can dry out their skin, and if their skin dry out. And of course dries out, they are not won't be able to breathe. And Additionally, earthworms don’t have eyes, but they don't have eyes. They can feel the still sense sunlight when they build a tunnel.dig tunnels. If they accidentally dig too close to the surface and detect light, they will turn around and tunnel deeper underground to stay safe.
Isaiah
We all in In the lecture lecture, the professor used the earthworm as an example to illustrate the next photo taxes. For first, the earthworm lived in the undergrounds negative phototaxis. First, earthworms live underground in dark space. It spaces, which is perfect for them to to because it helps them avoid the lights to light and keep the moisture in the skin. their skin moist. They need to brace stay moist because there they absorb oxygen through their skin. If an earthworm is extreme undergrounds. If the earthworm exposed to the lights they will light, it quickly escape escapes to avoid dehydration. They have special cells in the body to add the cells their bodies that are sensitive to light, allowing them to detect when they are getting close to the lights so surface. When they can avoid thesense light, they turn around and dig deeper underground to stay safe.
Mike
According to the reading passage negative photo-taxes Negative phototaxis refers to the behavior that of some animals will that try to avoid the light because of due to their physical features. But to allow These animals have special adaptations that help them to do it, some animals will have some special features to sense the light. And according According to the lecture, the professor mentions an gives the example about Earth War. It leaves on the ground of earthworms. Earthworms live underground because it needs they need to keep their skin moisture in order moist to go through absorb oxygen from the soil. But the sun will If they are exposed to sunlight, their skin can dry out their skin. So out, which is dangerous for them. Since earthworms don’t have eyes, they need to avoid the light. But they do not have the eyes, which means they need some organisms out of rely on special cells on their bodies called cells to detect light. When they dig and accidentally reach the light. And they are digging on surface, these cells sense the surface of sunlight, and the soil, they will turn worm reacts by turning around and dig digging deeper into a deeper area.the soil to stay safe and moist.

Photo-Texis Negative phototaxis is a biology term that will expose two lights from the sun or another source refers to the how certain animals when we move away from light sources, like the light source and you're seeking a darkness place and in sun, to seek dark places. In the lecture lecture, the professor mentions mentioned that animals will seeking a like earthworms need to avoid light because it can harm them. Earthworms live underground, where it’s dark and moisture place to forge moist, which helps keep their skin wet. If an earthworm accidentally digs up to cave moisture and when animals escape the darkness if not they will die so but not every animals have their eyes so they would dig in and on outside the surface until they escaped and is exposed to sunlight, it needs to escape quickly to avoid drying out and suffocating. Since earthworms don’t have eyes, they can’t see light the sunnights because same way other animals do. However, they have special cells on their skin that can sense light. If they detect sunlight, they react by turning around and digging deeper into the sunnights ground, where it’s darker and they would find a deeper and no longer sunlight holds on the ground so this is the action movementsafer for them.
