Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Explanation:

The microscope is an essential equipment used in science laboratories to view objects which are too small to be seen by the naked eye. Also certain processes which occur at the microscopic level can only be observed using a microscope.

There are many different types of microscopes. The compound light microscope is the one most commonly used in biological laboratories to view tissues and cells of organisms. It uses visible light which passes through two separate lens to magnify the image produced of a specimen.

The various parts of compound light microscope and their respective functions are given below:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

What would happen if all receptor proteins were removed from the membranes of all liver cells?

weqwewe [10]

If all receptor proteins were removed from hepatocytes' (liver cells') membranes, then the liver would no longer respond to hormones. This would be catastrophic to the metabolism, because the liver could no longer process nutrients such as glucose. Such a malady would prove fatal when not eating, because the lack of glycogen, cortisol, epinephrine (and other hyperglycemic hormones) woukd lead to hypoglycemic shock, coma, and death.
