Answer:
Answer No 1:
The three ways evolution is determined to have occurred are:
A. Molecular similarities
C. Homologous structures
E. Fossil evidence
Explanation:
Since the theory of evolution became popular, scientists have been looking for similarities and differences among organisms so that they can compare which organisms have a more closer ancestor together as compared to other organisms. Scientists look for molecular similarities, such as the similarities in the proteins and other molecules to depict relations among organisms. Homologous structures is a common term in evolutionary studies in which organisms which are more closely related are known to be more similar. Fossil evidences also help a lot in evolutionary studies.'

Answer:
Explanation:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
