The correct answer is option c, Cool Air moves upward in the center Warm air moves downward at the edge
Reason:
In a global convection cell less –dense air at the equator rises and flows towards the poles. And from pole, the dense air sinks down and flows back towards the equator. The equator is the center of the earth’s sphere while the poles can be considered to be the longitudinal edges. This movement of air is also supported by the Earth’s rotation known as Coriolis Effect.

The vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
After the fertilisation of the egg by the sperm in a frog, three regions are formed in the zygote. These are:
- Upper animal hemisphere or upper animal pole which shows pigmentation.
- The grey crescent which is a small area with almost no pigmentation. It is present in between the upper animal pole and the lower vegetal pole.
- Lower animal hemisphere or lower vegetal pole which is white in color.
Thus, the vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.

Process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
