yaroslaw [1]

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.

The degree to which the findings of a study may be applied to a larger population represents how ___________ a sample is. A. Ina
g100num [7]

Answer:

B. Generalizable

Explanation:

Generalizable means something's ability to be applied to a general or wide group. So, if something is generalizable that means that it is applicable to a wide group of things outside of the initial study. Thus, B is the correct answer because it is the only vocab word that properly describes how widely applicable the study is.

One of the best ways to generalize a study is to use random or probability sampling. This helps ensure that the findings of the study can be used by others in different situations.
