Answer:
The cytoplasm of the egg cell is same as like that of the ordinary cell's cytoplasm.
It has yolk in its center which contains nucleus, nucleolus and germinal spot.
The mammalian ova contains a small amount of nutritive yolk which provides the nourishment to the embryo for a time being.
The cytoplasm of the unfertilized egg contains some unevenly distributed proteins, specifically the cytoplasmic determinants.
These determinants are the substances that plays a major role in the oocyte formation and maturation. Sometimes they are clumped together and then divided heterogenitically.
Answer:
The correct answer is c. "enhance the binding of norepinephrine to its receptors".
Explanation:
Monamine oxidase inhibitors (MAO inhibitors) were the first antidepressant drugs to be developed and cause the accumulation of norepinephrine, dopamine, and serotonin. MAO inhibitors function by inhibiting the activity of enzymes that broke down these compounds. The accumulation of norepinephrine enhance the binding of norepinephrine to its receptors, allowing for a higher effect of norepinephrine.
Answer:
Selective breeding.
Explanation:
Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.
