Question
Reptiles excrete uric acid because…a) It is more toxic than ammonia.b) It has a low energetic cost.c) Their scales are not permeable to liquid.d) They live on land
Solution 1
Reptiles excrete uric acid primarily because they live on land. This is due to the fact that uric acid is less toxic than ammonia and can be stored in the body for longer periods of time without causing harm. This allows reptiles to conserve water, which is a crucial adaptation for living in dry terrestrial environments. Uric acid is also a solid, which means it can be excreted with minimal water loss. This is not related to the permeability of their scales, but rather to their kidney function and the need to minimize water loss. So, the correct answer is d) They live on land.
Solution 2
Reptiles excrete uric acid primarily because they live on land. This is due to the fact that uric acid is less toxic than ammonia and can be stored in the body for longer periods of time without causing harm. This allows reptiles to conserve water, which is a crucial adaptation for living in dry terrestrial environments. Uric acid is also a solid waste product, which means it doesn't require water for excretion, unlike ammonia. This is another important adaptation for water conservation. So, the correct answer is d) They live on land.
