The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.
The term which best describes species C relative to species A is Sister
species. This is as a result of them sharing largest number of derived traits.
<h3>What is Ingroup?</h3>
Ingroup is defined as the group in which organism belongs to. We were
told that A and C are ingroup species.
Species A sharing the largest number of derived traits with species C
means that they have similar traits and a common parent which is a
characteristic of sister species.

Answer:
There are many ways.
Explanation:
Humans have a combined respiratory and circulatory system, whereas insects do not. In humans, the air is brought in through the mouth/nose, through the windpipe, and into the lungs, the oxygen is absorbed into the bloodstream where it can be transported to muscles and organs. However, insects take in air through tiny holes in their thorax and abdomen. These are called spiracles. The oxygen is stored in many dorsal air sacs to be used. Then carbon dioxide is expelled through the spiracles.
B. Because the environment can not supply for the food and caring of the animal species that is growing larger.
