if a prey evolves to increase its defenses, its predator often evolves to counteract this change. a. True b. False​
DerKrebs [107]

Answer:

a. True

Explanation:  

Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.

A milk snake looks similar to the deadly coral snake. This is an example of A) warning coloration adaptive radiation B) cryptic
Damm [24]
In this case, c) mimicry is the answer. In Batesian mimicry in which harmless animals mimic toxic animals. In this case, I assume the milk snake is harmless and the coral snake is venomous. Since the milk snake has a trait similar to deadly coral snake, less animals would eat it thinking it is dangerous. Over time all the milk snake that look like the deadly coral snake would survive leading to evolution by natural selection. This would lead to more and more milk snake mimicking the resemblance of the deadly coral snake.

a) The deadly coral snake has a warning color adaptive radiation. If the question had described the environment and how the snaked adapted to the environment via warning coloration. This would've been correct.

b) cryptic coloration is more about camouflage with the environment. If the question had state how a certain feature help one of the animals blend into the background. This would've been correct.

d) I'm not sure whats different between this and a so i'll consider them both the same.
