Functions of astrocytes include all of the following except
Neporo4naja [7]

The question is incomplete. The complete question is as follows:

Functions of astrocytes include all of the following, except

A) performing repairs in damaged neural tissue.

B) guiding neuron development.

C) functioning in action potential transmission.

D) maintaining the blood-brain barrier.

E) creating a three-dimensional framework for the CNS.

Answer:

Functioning in action potential transmission.

Explanation:

Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.

Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.

Thus, the correct answer is option (c).

Which of these definitions have been paired with the correct type of cell?
patriot [66]

Answer:

B. Neurons are cells that conduct electrical impulses.

Explanation:

Red blood cells carry oxygen throughout the body. White blood cells protect against pathogens and aid in blood clotting after injury. Blood cells cannot contract.

Neurons generate and conduct electrical impulses. So this one is correct.

Epithelial cells line the cavities and surfaces of blood vessels and organs, protect underlying tissue, regulate the exchange of chemicals, and secrete various substances. They do not react to stimuli, however neurons do.

Smooth muscles helps the skeleton move, smooth muscle is found in blood vessels and some organs, and cardiac muscle helps the heart beat and pump blood. They are however, not components of blood.

Mitosis is a process used for normal growth and development. Explain how and why a mutation in a BRCA gene may affect the cell c
Romashka [77]

Answer:

The BRCA gene is a tumor-suppressor gene found in the breast; to be more specific, it produces proteins that suppress cancerous activities/abnormal growth in the body. A mutation in a BRCA gene would allow these abnormal growth activities to go unchecked and thus increase the rate of mitosis. Cell cycle checkpoints would significantly be worse at their jobs of checking and correcting for errors during the cell cycle. Tumors would result as well, as cancerous growth continues, and the tumor can become metastatic.
