Answer:
<h2>Gray matter: the gray matter is arranged intohorns: The posterior horn extends towards the dorsal root, the anterior horn extends towards the ventral horn, and the lateral horn lies between the posterior and anterior horns.
</h2>
Explanation:
The posterior horn is associated with the sensory nerve cells, the anterior horn is associated with the somatic motor neuron, and the lateral horn associated with the ANS ( autonomic nervous system).
Posterior horn:
Sensory neurons pass through the dorsal root ganglion after that the dorsal root and in the gray matter the neurons synapse to inter neurons in the posterior horn or may continue to the white matter and then enter the spinal cord.
Anterior horn:
The motor portion of the nervous system has two parts; i) the somatic motor system and the ii) autonomic nervous system. The somatic motor neuron stimulates the skeletal muscle with stimulation. The somatic motor neuron cell bodies (part of verve cell) are in the anterior horn of the gray matter.
Lateral horn:
The autonomic motor neuron send stimulation to smooth muscle, cardiac muscle, and glands etc. The cell bodies( part of nerve cell) of the autonomic motor neuron are in the lateral horn of the gray matter.
3. The answer to your question is B. Meiosis. Alleles undergo segregation during meiosis. The alleles will split into 2 daughter cells; one chromosome for each cell.
4. The answer is homologous chromosomes. Gametes have homologous chromosomes. A gamete is a mature haploid cell. It can either be a male or female gamete. Each haploid cell will unite with another haploid cell of the opposite gender for reproduction.
5. The answer is B. IBi or IBIB. This demonstrates the genotype that corresponds to human blood type.
