Answer:
The correct answer is option b, that is, an exaptation.
Explanation:
The co-option or the associated term exaptation illustrates a shift in the activity of a trait at the time of evolution. For example, a trait can evolve as it performed one specific activity, however, afterwards, it may start to perform another function. It is common in both behavior and anatomy.
A classic illustration of exaptation is feathers of birds, at the start they were evolved for monitoring temperature, however, afterwards they were amended for flight. Thus, if the given hypothesis is accurate than the modern wings of insects are an example of exaptation.
Adaptive radiation refers to the diversification of an array of organisms to hold a distinct ecological niche. The origination of mutation takes place because of the errors in the replication of DNA. The hox genes in the insects assist them to specify that what appendages will get produced in a segment.

Answer:
b. using negative feedback to decrease blood glucose levels
Explanation:
When the level of glucose increases in the blood and become higher than the normal level a negative feedback mechanism is initiated under the control of hypothalamus. which increase the metabolism of excessive glucose level present in blood and hence results in decrease or normalization of glucose level in blood.
