Question

1. why are reptiles considered "more advanced" than amphibians?
2. How do cold-blooded and warm-blooded animals adapt to their environments?
3. why do amphibians need to be in a moist environment
4. What do amphibians need to be in a moist environment?
5. Crocodiles and other reptiles are being hunted for their leather. Do you agree with this practice? why or why not?

Answer 1

Answer:

1.Reptiles are considered more advanced than amphibians because they have more advanced lungs. They also have dry scales that enable them to survive on dry conditions, unlike amphibians that needs their skin to be moist, in order to survive on land.

2.Cold-blooded animals have resistance against microorganisms, and when they are infected, they reduce body temperature as a defense mechanism. Warm-blooded animals have a much stronger immune system to defend against such microorganisms. They gain energy in the form of heat to regulate body temperature for survival.

3.First, it means that their skin helps them breathe, since oxygen passes easily through it. Second, it means that amphibians lose a lot of water through their skin. This is why most amphibians are found in moist or humid environments, where they can re-load their water reserves

5.yes, Most leather produced and sold in the U.S. is made from the skins of cattle and calves, but leather is also made from sheep, lambs, goats, and pigs. Other species are hunted and killed specifically for their skins, including zebras, bison, kangaroos, elephants, crocodiles, alligators, ostriches, lizards, and snakes

Answer 2

• 1.Reptiles are considered more advanced than amphibians because they have more developed lungs.
• They also have dry scales which allow them to survive in dry conditions, unlike amphibians which need moist skin to survive on land.

• 2.They can easily generate heat in the body. Cold-blooded animals cannot survive extreme temperatures and conditions.
• Warm-blooded animals quickly adapt to all environmental conditions and temperatures.
• They depend mainly on direct sunlight and the heat of the environment.

• 3.Firstly, it helps the skin breathe because oxygen passes through it easily.
• Secondly, amphibians lose a lot of moisture through their skin.
• Because of this, most amphibians live in damp or damp environments where they can replenish water bodies.

• 4.Most amphibians breathe through their lungs and skin. Their skin needs to stay moist to absorb oxygen, so they secrete mucus to keep their skin moist (if it's too dry, they can't breathe and die).
• Oxygen absorbed through the skin crosses the surface of the skin and enters directly into the blood vessels, circulating oxygen throughout the body.
• Sometimes more than a quarter of the oxygen consumed is absorbed directly through the skin. Tadpoles and some aquatic amphibians have fish-like gills that they use for breathing.
• There are amphibians that do not have lungs and breathe only with the skin.

• 5.The skins of crocodile and other reptiles are widely used in the manufacture of leather goods such as bags, wallets, belts, etc.
• Patterned with crocodile skin, this is a unique product that is difficult to find the same model.
