Due to extreme (too much) cell division, a mutation of cells will occur and that is the cancer within humans.
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.
Explanation:
Scientific laws and scientific theories are very similar.
They both discuss and observe phenomena that have already occurred and been evaluated.
The main difference between the two is that law defines nature and what it does conditionally, and the reaction of nature when these conditions encounter.
To sum it up, law discusses the behavior of something that transpires in many annotations.
A theory on the other hand discusses not the behavior, but the functions. The “why” factor so to speak.
