If a person comes in contact with this same virus years later, our body produces antibodies to get rid of or kill the virus
Explanation:
When a person is infected by a virus, the infected person's body develops antibodies as an immune response to act against the virus. Antibodies are produced as part of humoral immunity.
Antibodies work by neutralizing the viral activity, agglutination, phagocytosis or by complement system.
Antibodies are protein compounds which can recognize the invading pathogens and attack them.
Antigens or viral proteins in the virus leads to the production of antibodies in the host's body.
The specific antibodies triggers innate immune response upon detecting specific viral antigens when infected and will help the body to get rid of or kill the virus.

Answer:
(E) Soil disturbances can result in fewer blooms, and hence lower seed production.
Explanation:
According to the experiment, the eight control plots were left undisturbed, that is, their soil was not exposed to any disturbance. On the other hand, the soil of the experimental plots was disturbed during the removal of dandelion species. This disturbance might have resulted in reduced flowering in the experimental plots due to many reasons such as removal of fertile topsoil.
The reduced flowering in these plots might have caused lower seed set. The control groups had undisturbed soil which in turn favored more flowering and seed production than in the experimental groups.
