C4 plants occur more commonly in desert conditions because _____. a. they can fix carbon at the lower CO2 concentrations that de
ahrayia [7]

Answer:

a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed

Explanation:

C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.

Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.

<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>

The correct option is a.

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.
