Question

Which example shows an organism that cannot reach homeostasis through internal changes?

A) A reptile adjusting its body temperature by basking in the sun
B) A mammal shivering to generate heat in a cold environment
C) A fish regulating its buoyancy using a swim bladder
D) An insect adapting to changes in light by adjusting its compound eyes

Answer 1

Ectothermic animals cannot reach homeostasis through internal changes. The reptile adjusting its body temperature by basking in the sun is an example of an organism that cannot reach homeostasis internally.

Step-by-step explanation:

An organism that cannot reach homeostasis through internal changes is an ectotherm, also known as a cold-blooded animal. These animals rely on external temperatures to regulate their body temperature. The example that shows an organism unable to reach homeostasis through internal changes is option A) A reptile adjusting its body temperature by basking in the sun. Reptiles, such as snakes, need to warm up by basking in the sun and cool down by finding shade, as they are ectothermic and cannot internally regulate their body temperature like endothermic animals.
