Answer:
Dobutamine is a catecholamine with β-1 and β-2 adrenergic agonist properties which help improve myocardial contractility.
In patients with cardiogenic shock due to decompensated heart failure, dobutamine decreases left ventricular end-diastolic pressure and raises blood pressure by increasing cardiac output.
Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body. Transfer stains result from objects coming into contact with existing bloodstains and leaving wipes, swipes or pattern transfers behind such as a bloody shoe print or a smear from a body being dragged. Impact stains result from blood projecting through the air and are usually seen as spatter, but may also include gushes, splashes and arterial spurts. Blood spatter is categorized as impact spatter (created when a force is applied to a liquid blood source) or projection spatter (caused by arterial spurting, expirated spray or spatter cast off an object). The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source.

Answer:
E. is the correct answer
Explanation:
C. An increase in A produces an increase in X.
This statement can be directly concluded from the description of the effects of hormone A on the activity of X in the problem.
A. An increase in X produces an increase in A
This statement can be concluded from the fact that A and X work in a positive feedback mechanism.
In a positive feedback mechanism, a stimulus produces a response (secretion of hormone A) which has an effect (increase in X) that increases the original stimulus. A cycle is created, in which secretion of A causes an increase of X, and the increase of X causes an increased secretion of A.
<u>To shut off the positive feedback cycle, an outside factor is required.</u>
