Answer:
Mast cells. (Ans. A)
Explanation:
Mast cells are called the immune system of vertebrate species, they help to regulate some allergic responses, innate & adaptive immunity, and inflammation such as hypersensitivity. These cells circulate the amounts of their granules into the surrounding tissues, while stimulation by an allergen found and the process called degranulation.
Mast cells help to assist and awaken the immune system to local infection. Once these cells are activated, they generate inflammatory responses by secreting chemical mediators which are stored in preformed granules, and after activation occurs synthesizing leukotrienes and cytokines.
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.
