Answer:

The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.

Explanation:

In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.

After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.

The other options are not correct because:

A. Eyepiece is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.

C. Coarse Adjustment is the rough magnification, used for the initial approximation of the image.

D. Objective lens enlarges and defines the image of the sample on the slide.

In multicellular organism the energy is stored in the body in the form of _____ carbohydrate fats glycogen protein

Anastasy [175]

In multicellular organism the energy is stored in the body in the form of Glycogen.

The cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.

Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide (CO2) and water.

Other molecules, such as fatty acids and proteins, can also serve as energy sources when they are funneled through appropriate enzymatic pathways.

Answer:

Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function.

Explanation:

Hypertrophy is the term used to describe an increase in cell size. If the enough number of cells in some organ hypertrophy, the whole organ will also hypertrophy.

Compensatory hypertrophy is an increase in size of an organ or tissue after the organs and tissues are either damaged, removed, or cease to function. It can take place in a number of human organs and tissues such as the liver, the kidneys, the heart, the spleen, the lungs, the pancreas etc.

why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity

mixer [17]

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

EXPLANATION:

Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
But the polysaccharide like cellulose cannot be absorbed by our body.
Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
Thus, cellulose degradation requires a complex enzyme and cellulose.
