Why do frogs die in the getting hot water?

This is what we usually call boiling a frog in warm water, your temperature slowly rises, for him it is a process of slow adaptation, he will not think about refutating and fighting by himself, and it will be too late when he wants to fight.

People get heat stroke, and frogs get heat stroke. Because heat stroke is not painful, I just feel a little breathless, so I go into shock .......

It is due to the fact that it takes a period of time for the body to die, and the nerve reflex arc is manifested as muscle spasm twitching, and the human reflex arc stress response can often be seen in daily life. For example, when your fingers touch something hot, you will immediately withdraw your hand, but this is not directed by the brain. Rather, it is a stress response to the spinal reflex arc.

There is a case that proves that this stress response is not controlled by the brain. It's just dead, and the animal's nervous system isn't completely destroyed, so it's still moving. When the animal has just died, the nervous system has not been completely destroyed, and since the death of the organism takes some time, the nerve reflex arc manifests itself as a spasmodic twitch of the muscles.

The human reflex arc stress response can also be seen in daily life, which is not directed by the brain, but the stress response of the spinal reflex arc, such as finger touching.

There is a special type of electricity in animals called animal electricity.

Normal stress response in animals.

Frogs will drown in water.

Frogs will drown. Frogs are a very typical class of amphibians, and they also have the outstanding characteristics of amphibians, which can move on land as well as in water. The same is true for frogs, although they have different places of activity depending on their age.

Juvenile frogs, tadpoles that have just hatched from fertilized eggs, live in water.

Frogs, on the other hand, develop to the juvenile stage, and when they reach adulthood, they can live on land. At this time, the frog's respiratory organs are also changed. They breathe with gills during tadpoles, and with young frogs and adults, they breathe with their lungs.

Therefore, frogs drown because they breathe with their lungs and can only breathe on land. Although frogs can move in the water, they can't be active for too long as they can only breathe when they come out of the water. If they remain in the water for a long time, they are at risk of drowning or even drowning.

Of course, frogs can't stay out of the water all the time, because they need to be moistened to help their lungs breathe.

Frog science

The frog is a common amphibian that is widely distributed on all continents except Antarctica. Common areas include forests, streams and riversides, lakes, ponds, paddy fields, wetlands, and swamps.

The larvae are called tadpoles and have an ellipsoidal body with a long tail; During the growth process, hind limbs and forelimbs gradually grow, and the tail gradually shortens and disappears. The adult body has no tail, is quadruped, and the hind feet are more developed and can jump.

Frogs will die all the time in the water.

The respiratory organs of frogs are their lungs, so they have no way to breathe in the water.

Although frogs can be active in the water for a while, but not for too long, because the air that their lungs can store is limited, and they are fine until this air is exhausted, but after a long time, it can be dangerous and even dead.

However, when they are tadpoles, they can breathe with their gills and will not die if they are in the water all the time.

1. Can frogs breathe in the water all the time Frogs are amphibians, and within the different stages of their growth, the situation is very different.

Compared with the adult stage, there is a big difference in appearance between larvae and adulthood, but also in terms of body structure.

For example, when they were tadpoles, they lived in the water all the time and could not leave the water, precisely because the respiratory organs used in this stage of their lead field were gills, so they were able to breathe in the water all the time like fish.

However, when they reach the frog stage, they do not breathe with their gills, but develop the lungs as an organ and use the lungs to breathe.

At this point, the frog is no longer able to breathe in the water.

Some people think that frogs can breathe because they can move in water, but they are not.

Some of the air trapped in the frog's lungs can be used in the water for a period of time, during which time they can stay in the water, but when the air is depleted, the frog must come out of the water to breathe, otherwise there is a risk of drowning.

2. Will frogs die if they have been in the water The above Huaiyou shouted has been introduced, frogs use their lungs to breathe, and the lungs are their main respiratory organs, so they have no way to breathe in the water, so there is no way to take in fresh air.

The air in their lungs can be used to move them in the water for a period of time, but over time, their bodies will not be able to get fresh oxygen.

At this point, they may be at risk of drowning, and if they are long enough, they may also be at risk of drowning.

Of course, frogs generally come out of the water to breathe before they run out of air in their lungs.

No.

After learning "Amphibians", the students in our class had doubts about whether frogs can live in the water like fish when they grow up. Some say that amphibious should be able to live both in the water and on the shore; Some point to the concept in the book and say that when they grow up, they can only live on the shore.

The two sides argued, so they went together to ask the nature teacher, and the teacher said to us: "You love to think and are good at finding problems, but if you find problems, why don't you find the answer through your own ** like a scientist?" "That's right! I was determined to find out on my own.

The next day, I carefully caught two frogs in front of the ditch outside my house, and then brought a basin of water, immersed the frogs in the water, and after five minutes came out of the water, I saw that the frogs did not look strange in the slightest.

I dipped the other frog in the water, and after about ten minutes, I found that the frog was struggling a little, and its mouth was open and closed, as if it was drinking water, and I took it out of the water and put it on the ground to observe, only to see that the frog's stomach was bulging, and after a while, it jumped away, and it was still not drowned. I told the teacher about the experiment, and the teacher suggested suggestions for improving my experiment: First, I couldn't let it get hurt when I caught it.

The second is to use running water to avoid running out of oxygen in the water and causing death. On the third day, I started the experiment again, and the location was by the river. After I immersed the two frogs in the water, as time went on, the frogs struggled, their mouths seemed to be constantly drinking, and their bellies gradually grew larger.

I pity it, but for the sake of experimentation, I can only be sorry for it.
