Answer:
The answer is the tilt of earth.
Explanation:
Because the tilt of earth affects the angle of the sun's rays and causes the seasons in temperate regions. Even though the earth is far away from the sun, the northen hemisphere is tilted toward the sun, so the solar energy is more concentrated in this area.
The cerebrum/cortex - they're the same thing named differently
That is because gene expression is a process in the synthesis of proteins and without proteins our organisms could not function properly. Almost all things that occur in our body are results of proteins being synthesized and these proteins travel through our body activating other processes. When not synthesizing proteins, different types of RNA are synthesized.
