The large population of microbes that contribute to the gut microbiota and have an important role in food processing are called:
postnew [5]

The large population of microbes that contributes to the gut microbiota and have an important role in food processing are called <u>Commensal microorganisms</u> .

The human body is host to trillions  of microbes or bacteria. Most of these are useful but may become harmful when out of control.

The microbiota consists of a wide variety of bacteria, viruses, fungi ,and other microorganisms present in a singular environment such as the human digestive tract.

<h3>Gut microbiota : </h3>

The gut microbiota is vast and complex collection of microorganisms that profoundly affects human health gut microbiota are present in the digestive tract of vertebrates including humans.

The function of gut microbiota in body function includes harvesting energy from digested food, protecting against pathogens, regulating immune system and strengthening biochemical barriers of the gut and intestine changes in microbiota composition can affects these functions.

The normal gut microbiota have specific functions like host nutrition metabolism, maintenance of structural integrity of the gut mucosal barrier, helps in immunity, protect against pathogens.

<h3>Commensal microorganisms:</h3>

Commensal microorganisms are those type of microbes that reside on either surface of the body or at mucosa without harming human health . commensal bacteria are 10 times more than the cells present in our  body.

Example - Streptococcus oralis and Streptococcus salivarius .

Commensal microorganisms plays an important role against pathogens including respiratory pathogens. It acts on the host's immune system to induce protective response that prevents colonization an invasion by pathogens. On the other hand these bacteria can directly inhibits the growth of respiratory pathogens by producing antimicrobial products .it also competing for nutrients and adhesion sites. Provides the host with essential nutrients.

<h3>What are microbes ?</h3>

Microbes are tiny living things that are found all around us and  are too small to be seen by eye. They live in soil, water and in air. The human body is the home of trillions of microbes.

Answer:

1. Sex chromosomes.

2. Genotype.

3. Allele.

4. Meiosis.

5. Gametes.

6. Genome.

7. Mitosis.

8. Homologous Chromosomes.

9. Crossing over.

10. Gremlins cells.

11. Zygote.

12. Somatic cells.

13. Independent assortment.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

The various terminologies used in the field of genetics includes;

1. Sex chromosomes: The chromosomes that determine your biological sex -X and Y.

2. Genotype: The set of alleles an organism inherits.

3. Allele: Versions of a gene that arise through mutation.

4. Meiosis: Cell divisions that occurs in sex cells.

5. Gametes: Egg and sperm cells.

6. Genome: The complete set of genes in an organism.

7. Mitosis: Cell division that occurs in all body cells.

8. Homologous Chromosomes: The matching chromosomes a person inherits from their mother and father.

9. Crossing over: A process that increases genetic diversity during meiosis.

10. Gremlins cells: Cells that divide to produce gametes.

11. Zygote: The cell formed when an egg and sperm meet

12. Somatic cells: Body cells (hair, skin, brain, bone, etc.)

13. Independent assortment: The random lining-up of homologous pairs at the cell's middle.
