Answer: The downstream components will be altered and ultimately affect production of glucose.
Explanation: Epinephrine is a hormone that belongs to a class of biomolecules called catecholamines. When it reaches the target cell it binds to a receptor that is connected to an enzyme called adenylate cyclase that converts ATP into cAMP(cyclic adenosine monophosphate). cAMP plays an important role in the phosphorylation of proteins which alters their activity. In this case the activity of the enzyme that hydrolyses glycogen to glucose. When caffeine blocks the activity of cAMP it ultimately inhibits the action of the downstream components.
The correct answer is A. A serious disease outbreak that infects hundreds of people
Explanation:
In science, the epidemiology is a fill that studies diseases especially in terms of the way diseases emerge and then spread in populations or the way diseases become epidemics. This implies, epidemiologists focus on diseases outbreaks rather than on inherited diseases. Moreover, epidemiology plays an important role in preventive health as well as actions to control epidemics. Considering this, it can be concluded an epidemiologist is likely to study " A serious disease outbreak that infects hundreds of people" because epidemiologists focus on the causes, transmission, and outbreaks of epidemics which are diseases that spread in a population.
