Answer:
When selecting the proper microscope to view a sample, you should choose a simple microscope to look at a fresh lung tissue (whole organ), a compound microscope to observe the patterns of cells on a slide, and an electron microscope to study individual organelles within cells in great detail.
Explanation:
Many types of microscopes are available, they are used by researchers, medical technicians and students on a daily basis upon their need.There are different kinds of microscopes.
The simple microscope is generally considered to be the first microscope ,it provides information about biological specimens. Its magnifying power ranges between 200 and 300 times. it can easily be used to magnify a whole tissue.
With two lenses, the compound microscope offers better magnification than a simple microscope,the second lens magnifies the image of the first is high magnification, which allows users to take a close look at objects too small to be seen with the naked eye, observing pattern of cells.
Electron microscopes uses electrons rather than light for image formation, creating a magnified image, and samples are scanned in a vacuum so they must be specially prepared. An electron microscope offers a high degree of both magnification and resolution, making it useful to study cells in detail.
The answer is withdrawal symptom. This is caused by the abrupt discontinuation or decrease in intake of medications or recreational drugs, in this case, alcohol. It begins with substance dependence where the body of the subject adapts to a state of repeated alcohol administration. WIthdrawal offsets the body of its balance hence cravings and withdrawal symptoms.

Channel proteins that form a narrow passageway in gap junctions are known as <span>connexons
</span><span>Connexons are assemblies of six proteins that form a pore or a narrow passageway between the cytoplasm of two adjacent cells.
These passageways allow the bidirectional passage of iron and signals between the cells. </span>
