A gene plz don't report if this is not what your lookin for
Answer:
G₀ being a stage of the cell cycle that is the resting stage, where there is no cell division, the cells that would remain in the G₀ stage throughout life are the neurons (option c).
Explanation:
In the G₀ phase, considered outside the cell cycle, there is cell metabolic activity but no cell division, since cyclins and cyclin-dependent kinases disappear. Some cells, such as neurons, do not undergo cell division throughout the life of an organism, so they remain in G₀.
In some organs, such as the liver, the hepatocyte may remain in G₀ until the organ receives an injury, and may regenerate by cell division. This is not the case of neurons, which maintain a constant quantity throughout life.
The other options are not correct because:
<em> a. </em><em><u>Cancer cells</u></em><em> are characterized by a very active and uncontrolled cell division process.</em>
<em> b. </em><em><u>Liver cells</u></em><em> can remain in G₀, but cell division can be activated when required.</em>
<em> d. </em><em><u>Epithelial cells</u></em><em> are constantly dividing, since it is a tissue that undergoes frequent cell replacement.</em>

Answer:
foreign cells.
Explanation:
Humoral and Cell-Mediated Immune Responses The immune system distinguishes two groups of foreign substances. One group consists of antigens that are freely circulating in the body. These include molecules, viruses, and foreign cells.
