The answer is; chromosomes.
During interphase, the chromosomes are usually hard to visualize even under a microscope becaue they are long thin threads called chromatin. During the initiation of mitosis, the chromatin undergo structural changes that condense and shortens them and they becomes visible to even a light microscope.
Answer:
The binding of ACh to the muscarinic receptor indirectly affects the permeability of K⁺channels. This can produce hyper polarization in some organs if channels are opened, and depolarization in others if channels are closed.
Explanation:
For example, in the heart it is the beta-gamma compound that fixes to the K+ channels of heart muscle and sources them to exposed. This leads to K+ dispersion out of the cell and the cell converts into hyper polarized consequential in a reduction in heart rate. In contrast, in smooth muscle of the stomach the alpha sub unit fixes to K+ channels producing them to close. This decreases the external diffusion of K+ and the cell converts depolarized ensuing in smooth muscle contraction.
Basaltic magmas tend to be fairly fluid (low viscosity).
So, C.
The aorta is the main artery of the body which makes sense why it would be thicker than the other vessels in the human body. The aorta is of vital importance because it is responsible for distributing oxygenated blood to all parts of the body.
