Answer: B

Explanation:

The question wants to know what the expression is directly dependent on.

The sequence of genetic expression goes like this:

  DNA -> RNA -> protein

If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.

 

The  Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.

Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.

The answer is B because your DNA is what makes you uniquely you and have your own traits.

3. Allele.

4. Meiosis.

5. Gametes.

6. Genome.

7. Mitosis.

8. Homologous Chromosomes.

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.

Match the description of each plants with the group to which the plant belongs. (Match each number to a letter please!)
Hoochie [10]

The right matches are :

A. bryophyte  ==> 3.

B. pteridophyte  ==> 2.

C. gymnosperm  ==> 1.  

D. angiosperm  ==> 4.


These four types of plants are cormophytes.

Bryophyte is a terrestrial plant belonging to the family Bryophyta, which does not have a real vascular system.

Gymnosperms are the first order of didynamy containing phanerogamous plants whose eggs are not enclosed in closed carpels.

Angiosperms are plants whose seeds are enclosed in a closed ovary.

Pteridophytes produce neither flowers nor seeds but are vascular plants.
