Answer:
Zona fasiculata.
Explanation:
Zona fasiculata is present in the middle of the adrenal cortex lies beneath the zona glomerulosa. This layer produces the glucocorticoids especially cortisol that regulates the glucose metabolism.
The zona fasiculata layer can be easily determined historically. This layer of adrenal cortex contains the long cords or column cells and the cells are plump with liquid.
Thus, the correct answer is option (b).
The answer is c. Deciduous trees lose their leaves to prevent nutrient and water loss.
Losing leaves is a trees' strategy to survive cold winters. It is known that trees primarily lose water through leaves. In the winter, there is no enough water to replace that lost water. If the trees were not to throw away their leaves, they will soon dry out. Also, before falling the leaves begin, reabsorb all nutrients from the leaves and store it for the cold winter. Thus, losing leaves is important to prevent both nutrient and water loss during the winter.
Gill pouches seems like the most reasonable answer, only because a chordate needs a notochord and a nerve cord.
Answer:
The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.
