Answer:
<u><em>Active Transport</em></u>
Explanation:
<u><em>active transport
</em></u>
During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Answer:
The correct option is C) Heparin has its effects reversed with the administration of protamine sulfate.
Explanation:
Heparin is an anticoagulant, that is, it works by decreasing the ability of blood to clot, helping to prevent the formation of clots as well as stopping the subsequent extension of any existing clot. Through the neutralization of thrombin, it prevents the conversion of fibrinogen to fibrin, and thus, prevents the formation of a stable clot by inhibiting the fibrin stabilizing factor.
Protamine sulfate is a heparin antagonist, forming with it inactive complexes without anticoagulant effect, that is, the protamine, in the presence of heparin, which is acidic in nature, through the formation of stable salts, cancels the anticoagulant effect of both substances, neutralizing and reversing the anticoagulant action of heparin.
