Question

Which of the following is an example of a physical structure used for survival in the organism's environment?

A. Layers of blubber on a walrus
B. Whale migration to warm waters for mating
C. Opossum playing dead to fake out predators
D. All of the other answer choices

Answer 1

The physical structure used for survival in an organism's environment is layers of blubber on a walrus, which insulates and conserves body heat, allowing them to maintain homeostasis.

Step-by-step explanation:

The example of a physical structure used for survival in an organism's environment is A. Layers of blubber on a walrus. Blubber is a thick layer of fat, also present in other marine mammals like whales, that provides insulation and helps maintain a constant body temperature in cold water environments. This adaptation allows these animals to survive in habitats that could otherwise be too extreme due to low temperatures. The layers of blubber work as part of a mechanism to conserve body heat and sustain homeostasis even amidst the harsh conditions of their environments.
