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.
<span>The question makes it seem that you looked through both types of microscopes at specific samples? As for how they would differ, a light microscope's level of magnification is limited by the physical characteristics of light and therefore can only see objects as small as organelles inside of a cell. A scanning electron microscope, however, does not use light, it uses a beam of electrons to visualize the sample. Electrons are much smaller than the light beam and are able to image much smaller objects, such as molecules and atoms.</span>
Isaac Newton published a comprehensive theory of gravity in 1687. Though others had thought about it before him, Newton was the first to create a theory that applied to all objects, large and small, using mathematics that was ahead of its time.
A divergent boundary is a place where two tectonic plates are pushed apart by the formation of new crust rising up from the mantle. At a divergent boundary you would expect to find:
Rift Valley
Mid-Ocean Ridge
Deap Sea Trench
New Oceanic Crust
