C. Florida black bears have less territory and cannot risk a long hibernation.
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.
<span>Eating nonfood items like clay, erasers, and chalk during pregnancy is known by the medical name of geophagy. Pregnant women does crazy things that gives them a weird number of choices when it comes to food cravings. The main reason is to protect her and the baby from harmful microorganisms and toxins and to suffice the lack of vitamins. Clay though has a high mineral content, that is rich in magnesium, copper, iron and calcium. While it may be weird, these minerals are the fundamentals of a human diet especially during pregnancy.</span>
