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.
Phrenologists did not critically examine their data.
Answer: Externalities are side effects (good or bad) that occur when a person or a company performs an activity and does not assume all the costs of it, or all the benefits that could be reported. In this way we can distinguish:
Negative externality: Arises when not all the costs of a negative effects are assumed. In these cases, a social cost is generated, since it is the whole society that suffers the consequences of its actions. And the market price does not collect this cost.
Positive externality: Arises from a positive effect that is not reported as a benefit. An example of positive externality that we can mention is scientific research, from which society in general benefits. In these cases, market place do not reflect the real benefits.

He wants to change these seating patterns so as to see how it will affect the behaviors of other employees.
