We can clearly see that the South eastern coast of Australia has more number of people diagnosed with cancer.

The South western and the Northern part also records a sizable amount of skin cancer cases.

How are hormones and prostaglandins similar? how are they different?

On the other hand, prostaglandins differ from hormones in that they are not produced at a specific place but in many different places throughout the body. Also, the metabolic degradation of prostaglandins is very rapid.</span>

Tasya [4]

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.
