Answer:

A haploid cell can be described as a cell which contains a single set of chromosomes. For example, the sex cells in humans i.e the egg cell and the sperm cell contains 23 chromosomes each.

A diploid cell can be described as a cell which contains two set of chromosomes or chromosome pairs. For example, all the cells of the human body, except the sex cells, contain 23 pairs i.e 46 chromosomes.

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.

Travka [436]

Answer:

Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends  this information through a(n)  <em>sensory</em> neuron to his CNS. A(n) <em>interneuron</em> picks up  this information and carries it to <em>motor neurons of the CNS</em>, which sends a signal to the muscles in his foot causing his  foot to pull away from the rock.

Explanation:

The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.
