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>
A. older fossils are found in deeper layers of undisturbed rock strata.
