Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
In biology, the study of biosystematics helps scientists understand the evolution of organisms. Without it, they wouldn’t have been able to logically theorize where life came from. In modern biology, biosystematics is used to group, classify, and label organisms based on their genetic makeup and environmental habits.
geological isolation, if the birds that develop mutations do not have any competition they can survive.
If a scientist is studying an infectious agent in a lab, it is very important to understand the implications of evolution because then the scientist will be able to predict how the agent will adapt to different hosts.
