Question

Which below is an adaptation that favors the survival of an organism?

Answer 1

A is the answer, a squirrel wouldn't need to swim, a desert animal needs to be able to deal with low water conditions because there is little water in the desert and birds need to be able to groom themselves.

Answer 2

Ans. (A). Proteins expressing color in butterfly wings mutate to improve camouflaging abilities of butterflies.

Adaptation is described as permanent change in organism due to mutation that leads to better survival of that organism.  

Camouflage helps the butterfly to hide in its surrounding environment to avoid predators. So, if a mutation leads to expression of protein in butterfly's wings that improve camouflage in butterfly will show an adaptation as would lead to increased survival of that butterfly population.

Thus, the correct answer is option (A).
