Question:
Why does the virus need a host in order to multiply?
Answer:
Use the cells' resources
Explanation:
A virus is typically a is a DNA or RNA moiety encased in a protein capsule. The capsule is usually specific to the class and type of virus and it lends to the virulence of the entity. In order for infection to be established the virus must bypass the host's immune system and it's immune response and invade a host cell. There it will incorporate it's genetic material into the hosts' nucleus and harness the machinery that it does not in itself possess in order to make multiple copies of itself. It uses the host cell's DNA replication machinery, proteins amino acids and energy among other things before it bursts out of the cell and destroys it. This continues for some time and eventually the host may perish. The virus will then be passed along to a different host where it's replication using that hosts machinery will continue.

Answer:
(B) Noise, pyschological
Explanation:
Psychological noise occurs when the person trying to heed the propagated message begins to let his mind wander over another subject. It is a noise present in the head of the person, which ends up impeding the understanding of the message, that is, the communication itself. Like Tracy, who is trying to make a communication about work, but her mind insists on thinking about the death of her dog.
Answer:
Grupos sociales pueden tener varias razones para oponerse a las maquilas que se instalan en las zonas francas:
- Consecuencias fiscales: una zona franca es un lugar donde a las empresas se les cobran menos impuestos. Estos menores impuestos significan una reducción del ingreso fiscal que reciben los gobiernos, y que podría ser invertido en servicios sociales como educación y salud.
- Explotación laboral: además de los bajos impuestos, las zonas francas también atraen compañías por los bajos sueldos que pueden pagar a los trabajadores.
- Protección a la industria nacional: muchas maquilas son sucursales de empresas manufactureras extranjeras, no nacionales, y para algunos grupos, la industria nacional debería tener preponderancia sobre la industria extranjera.
