The right options are;
are disease-causing microorganisms
can be fatal
A pathogens is any substance or organism especially microorganisms that are capable of causing diseases. Pathogens include; bacteria, viruses, protozoa or fungi. Microorganisms are not considered to be pathogenic until they have reached a population size that is large enough to cause disease. Pathogens can be fatal and can be treated. Pathogens are diverse and they occupy essentially every environment.
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.
The right answer is Schwann cells.
<span>Schwann cells, or neurolemmocytes, are peripheral glial cells. With oligodendrocytes, they make myelin sheaths around the axons of neurons, protecting them and increasing the speed of electric nerve impulses.</span>
