Answer:
Norepinephrine
Explanation:
Nerve cells and circulating hormones are the one responsible for vasoconstriction of the vessel walls, as they do not enter the tunica media of the blood vessel, the nerves do not synapse directly on the smooth muscle cells. Instead, they release the neurotransmitter, norepinephrine, which diffuses into the media and acts on the nearby smooth muscle cells, which result in contraction of the entire muscle cell layer and thus reducing the radius of the vessel lumen.
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.
