Answer:

a = increased temperature increases the kinetic energy of the gas molecules.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi

Naya [18.7K]

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:

Primordial follicle

Primary follicle

Secondary follicle and

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 granulous cells. 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 zona pellucida and corona radiata .

The follicular antro (The highlighted structure) separates the oocyte from the externally located granulosa cells or follicular cells.

What does that leave as the source for the energy that is now in the fold molecules?

Ivahew [28]

Answer:

Explanation:

chaperonins

Members of the Hsp60 family (also called chaperonins) facilitate the folding of proteins into their native conformations. Each chaperonin consists of 14 subunits of approximately 60 kilodaltons (kd) each, arranged in two stacked rings to form a “double doughnut” structure

Compare and contrast the traits of viruses and bacteria. Is a virus considered a living thing? Explain your answer in 3–5 senten

kkurt [141]

Answer:

Bacteria are single-celled organisms that live in different environments, including cold and hot, and they can also live on or inside the human body.

Most types of bacteria are harmless, on the contrary, they help in the process of digesting food, attacking other microbes and fighting cancer cells, and less than 1% of bacteria are bacteria that cause diseases.

As for viruses, they are very small organisms, smaller than bacteria, consisting of DNA and a protein that coat them, and unlike bacteria, a virus does not reproduce without its presence in the cells of living organisms.
