Stem cell are important because stem cells represent an exciting area in medicine because of their potential to regenerate and repair damage tissue .
The ecosystem will collapse and fail because every species are needed and play a role in the ecosystem.
The reason why socialist governments often turn authoritarian are:
- Having too much power eventually corrupts the holder.
- When resistance builds, they try to suppress it because they feel socialism is the best way.
<h3>Why does socialism sometimes become authoritarianism?</h3>
Socialist governments tend to have too much power vested in the Executive in order to properly plan the economy. As a result, they often get corrupted because their power is inhibited.
When this corruption leads to inefficiency, authoritarianism is introduced to ensure that the citizens cannot overthrow the government which wants to keep power.

Answer:
Granulosa cells
Explanation:
Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).
The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:
- De Graaf follicles (This is the one shown in the image)
Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of <u><em>granulous cells</em></u>. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.
The oocyte at this point gets surrounded by <u>zona pellucida</u> and <u>corona radiata </u>.
The follicular antro (The highlighted structure) separates the oocyte from the externally located <u>granulosa cells</u> or follicular cells.
Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered. These findings further back with the theory that selection is context-dependent, as dark mice were preferred in some contexts but not in others.
<h3>
What is mutation?</h3>
A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.
In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.
New mutations cause black color.
- Fur color is controlled by many genes (4:29).
- Most genes are identical, but dark and light rock
- pocket mice differ in one gene (Mc1r; 4:55).
