The correct answers are A. The cell membrane is very selective, D. The cell membrane is a protective layer surrounding a cell, and E. The cell membrane allows waste to leave the cell.

Explanation:

The cell membrane is a membrane composed of lipids and proteins that surround and define every cell. This membrane had an important role because it regulates the substances and particles that enter and exit from the cell. The cell membrane is very selective as just certain substance can go out an in; for example, the cell membrane allows oxygen to enter into the cell and waste to leave the cell as this preserves the balance in the cell and it is necessary. Moreover, the cell membrane protects the cell from outside isolating it and avoiding nocive particles enter. According to this, it is true this structure is very selective, it acts as a protective layer and also it allows waste to leave the cell.

In your own words, explain why a virus such as the rhinovirus, which relies on close contact to spread, might evolve to favor le
Zielflug [23.3K]

Rhinoviruses are transmitted through the air or via contact. We might expect this sort of transmission to require a fairly healthy host (one who gets out and comes into contact with others) and, hence, to select against virulent strains. If we take precautions and try to stay away from people or avoid any contact with people, more hand-washing stations, increased attention to sanitization, and isolation of patients will help to reduce the transmission of the disease and, in the process, may favor the evolution of less virulent strains of the virus.

Katena32 [7]

Answer:

<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone

<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis

Explanation:

Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
