When a single cell undergoes many mitotic divisions in the nucleus, producing many daughter cells, it has conducted B) Multiple fission.
Multiple Fission is a type of asexual reproduction in which the parental body divides into many daughter cells simultaneously during the unfavorable conditions to increase the chances of survival of daughter cells.In this, the reproductive unit is whole parental body.
Hope this helps :)
Answer:
The correct answer would be 2,70,000 nucleotide long gene.
The gene refers to the protein coding sequence of the (deoxyribonucleic acid) DNA.
The nucleotide sequence of a gene corresponds to the codon sequence if mRNA. The codon sequence of mRNA then codes for the amino acid sequence of the protein.
The codon refers to the set of three nucleotide which codes for a specific amino acid. For example, CAG codes for glutamine, AUG codes for methionine et cetera.
So, if the polypeptide chain consists of 90,000 amino acids then it must contain 90,000 x 3 nucleotides which are equal to 2,70,000 nucleotides.
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.

Explanation:
The wind and water can break down the landscape and affect its physical formation. Water for example can break down rocks and make a ditch from 1 foot deep to 6 feet deep.
