A student is testing isopods’ response to light. Isopods (also known as pill bugs or sow bugs) are crustaceans that breathe through organs that need to be kept moist. The results of the experiment show that the isopods move away from light and gather in dark areas as soon as they hatch. Select two statements that explain whether this behavior by the isopods is innate or learned and what adaptive advantage this behavior may have.
A. This behavior appears to be innate, because the isopods could not have learned the behavior during the experiment. The animals exhibited this behavior as soon as they were exposed to the light, right after they hatched.
B. This behavior has an adaptive advantage for isopods because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring.
C. This behavior appears to be learned, because the isopods only exhibited this behavior after they were exposed to the light in the experiment.
D. This behavior is artificial and therefore does not have an adaptive advantage for isopods in nature, because those isopods that moved to dark, moist areas would more likely become food for predators and would not survive.

The behavior of isopods has an adaptive advantage for them because dark areas in nature are usually moist. Those isopods that moved to dark, moist areas were more likely to survive and pass the genetic trait to their offspring. Thus, the correct option is B.

What is Adaptive advantage?

An adaptive advantage is a reproductive advantage in an organism that derives from being well-suited to the specific environment in which it lives. Adaptive advantage is likely to result in an organism that is producing more offspring than those organisms without the adaptive advantage.

Isopods show adaptive advantage because isopods move to dark areas away from light which are usually moist. The isopods that moved to the dark, moist areas were more likely to survive and pass the genetic trait to their offspring than other isopods.

Therefore, the correct option is B.
