Answer:
300 kcal of energy.
Explanation:
Grass produces 30,000 kcal of energy through the process of photosynthesis. The zebra eat this grass and would acquire 3000 kcal of energy because only 10% of energy will transferred from one trophic level to another. In this way, when the cheetah feed on zebra, it acquire 300 kcal of energy and again 10% of energy is transferred from zebra to cheetah while the remaining release in the atmosphere in the form of heat energy.
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.
