Answer:
It neutralizes the virus
Explanation:
When a vertebrate is infected with a virus, antibodies are produced against many epitopes on multiple virus proteins. A subset of these antibodies can block virus infection by a process that is called neutralization.
Antibodies can neutralize viral infectivity in a number of ways, as summarized in the illustration. They may interfere with virion binding to receptors, block uptake into cells, prevent uncoating of the genomes in endosomes, or cause aggregation of virus particles. Many enveloped viruses are lysed when antiviral antibodies and serum complement disrupt membranes.

Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
