Glucagon and Insulin are both hormones that regulate blood sugar levels and they are both produced by the pancreas.
When sugar levels in the blood are high the pancreas secretes insulin from its beta cells and releases it into the blood stream. Insulin causes the red blood cells, fat cells and muscle cells to absorb sugar from the blood .
When sugar levels are low, the pancreas secrets glucagon from its alpha cells which stimulates the liver to release the glucose that is stored in its cells.
Thus these two hormones work in the body to keep sugar levels balanced.
The endometrium is the inner lining of the uterus. During the ovulation period, this wall thickens as it prepares the uterus for the eventual fertilization of an egg cell. It is composed of a basal layer and a functional layer, in which the latter sloughs off/sheds off during menstruation.
Therefore, it is the ENDOMETRIUM layer <span>of the uterus undergoes dramatic changes in thickness and structure during the uterine cycle responding to hormones.</span>
Water vapor is the basic ingredient
Answer:
Option (D)
Explanation:
The tropical rain forest and tropical dry forest lies on the tropical regions of both the hemisphere. These are the regions on and around the tropic of cancer and tropic of capricorn. In the tropical rain forest, the rate of precipitation is higher than the rate of evapo-transpiration, so the temperature remains relatively cooler. Whereas, in the tropical dry forest, the rate of evapo-transpiration is more than the rate of precipitation, as a result of which the temperature remains comparatively high.
The tropical dry forest is very good for agricultural purpose, as it contains nutrient rich soil. So it has been destroyed to a greater extent for agricultural use, grazing of animals.
Whereas, the tropical rain forest is not suitable for the agricultural use because the soil here are affected by the rainfall, that washes away the nutrients, making the soil less fertile.
Thus the correct answer is option (D).
