If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.
Types of passive transport include diffusion and osmosis, both of which involve moving down a concentration gradient and thus not requiring energy.
Active transport moves up the concentration gradient and does require energy.
Perhaps someone who has taken bio within the last several years can correct anything I might have misstated here.
Answer:
The correct answer is option C. "disruptive selection".
Explanation:
Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.
