Answer:
B. decreases salivation and increases blood pressure
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.
The sympathetic nervous system is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.
Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.
The control of salivary production by the sympathetic nervous system leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.

Answer:
C.
pump blood, which carries nutrients and oxygen to the cells of the body.
Autotrophs are organisms that uses light energy or energy stored in chemical compounds to make energy-rich compounds. The reason why autotrophs always occupy the lowest level of ecological pyramids is because they are the link between the sun's energy and the organisms that cannot manufucture their own food. Without an abudant amount of autotrophs we would be severely lacking in atmospheric oxygen and food.
