Biology

mr Goodwill [35]3 years ago
8 0

Answer:

There is a great difference between light and scanning electron microscope. The source of illumination is light rays in light microscope while in scanning electron microscope electrons are the source of illumination.

The resolving and magnification power of scanning electron microscope is much greater than that of a light microscope. The magnifying power of a light microscope is 1000X and of electron microscope is 10,00,000X.

In light microscope image is seen through the eyepiece while in scanning electron microscope it is seen on a fluorescent screen. Even small specimens up to 0.1 micrometers can be seen by scanning electron microscope which is not possible to see by light microscope.

All of the following are major functions of proteins except 1.control of biochemical reactions. 2.support for organs or tissues.
Galina-37 [17]

Answer:

<h2>5.storage of energy</h2>

Explanation:

  • Proteins are important biomolecules that are a type of macromolecule.
  • This macromolecule is made up of a monomer that is called amino acid.
  • There are many functions of the protein molecules in living organisms.
  • They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
  • Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
  • Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
  • They also play an important role in the immune system.
  • The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.

KengaRu [80]

Answer:

B. False

Explanation:

No; only a small percentage of variants cause genetic disorders—most have no impact on health or development. For example, some variants alter a gene's DNA sequence but do not change the function of the protein made from the gene.
