<span>The unique aspect of norepinephrine release is that , they are released by axon Varicosities. Long postganglionic sympathetic fibers lead from the sympathetic chain to the target organ where they are terminated with bulbous enlargements called varicosities. The modified axon endings release a neurotransmitter, in the case of sympathetic nervous system norepinephrine, into its surroundings. Norepinephrine is known to be neurotransmitter for postganglionic sympathetic adrenergic nerves and functions by mobilizing the brain and body for action. Varicosities can be thought of as a series of small beads strung on a string, each axon has a relatively high number of these endings. The varicosities have no postsynaptic terminal assigned.</span><span />

Which three of the following best describe what would happen if mitosis did not take place?
vaieri [72.5K]

Mitosis refers to the procedure of cell division, in which a cell goes through a carefully mediated nuclear division, which results in the production of two genetically similar daughter cells. The mitosis comprises five active stages, that is, prophase, premetaphase, metaphase, anaphase, and telophase.  

In a single-celled species like an amoeba, it is the process of mitosis by which the cells reproduce. After undergoing through the five stages of mitosis, it is via the procedure called cytokinesis, the single cell dissociates into two similar cells, thus, completing the reproduction.  

During injury, the process of mitosis takes place to substitute the damaged cells. This repair is mainly essential for the blood vessels and skin that safeguards the organs and muscles in the body. Mitosis also assists to substitute the lost blood via a wound.  

Thus, if the process of mitosis would not take place, then the organism would remain a single-cell, asexual reproduction would not take place, and the tissues of the body would not be able to repair themselves.

Stem cells are undifferentiated cells that have the ability to continue to grow and divide in their non-specialized state for lo
strojnjashka [21]

Answer:

The correct answer will be option-D

Explanation:

Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.  

The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.

Thus, option-D is the correct answer.

GrogVix [38]

Explanation:

A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.

Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
