Question 3

The key difference between ectotherms (such as lizards)and endotherms (birds and mammals)is that

Accepted Answer

The key difference between ectotherms and endotherms is that ectotherms rely on the environment for energy to regulate their body temperature while endotherms generate heat metabolically from within their own bodies. This means that ectotherms are often seen basking in the sun or seeking shade whereas endotherms can regulate their body temperature internally. Choice B, D, and E are all incorrect as ectotherms can regulate their body temperature to some extent and endotherms rely on their own metabolic heat, not sunlight or brown fat.

Question 5

The organ system you can easily see is the _______ system.

Accepted Answer

The integumentary system includes the skin, hair, and nails, which are all visible on the outside of the body.

Question 6

Whale blubber represents which of the following strategies for thermoregulation?

Accepted Answer

Whale blubber serves as insulation to trap existing heat within the body, allowing the animal to maintain a high body temperature even in cold temperatures. It is not involved in shivering or generating additional heat through thermogenesis.

Question 7

The organ system below that regulates many body functions is the _______ system.

Accepted Answer

The endocrine system is responsible for regulating many body functions through the production and secretion of hormones. These hormones act on distant target cells to coordinate the actions of multiple organ systems and maintain homeostasis. The integumentary system is primarily responsible for protection, while the skeletal system provides structural support. The digestive system is responsible for processing and absorbing nutrients, and the lymphatic system is involved in immunity and fluid balance.
