Answer:
1. At the end of S phase- 20 pg DNA
2. At the end of G2 phase- 20 Pg DNA
Explanation:
The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.
During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.
In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.

Answer: Corpus callosum intergate information sent to the brain by the nervous system to the right and left hemisphere.
Explanation: Corpus collasum is found in the brain. Its made up of millions of axons that interconnects the two hemispheres. It passes sensory, cognitive and motor information to the cerebral cortex of the right and left hemispheres accordingly. The right hemisphere receives and controls the left side of the body basically responsible for arts and creativity. The left hemisphere controls the right side of the body and is responsible for logical reasoning, reading and writting.
The corpus collasum is located in the middle of these two hemispheres, its a bridge that passes information to its given hemisphere.
According to uniformitarianism, (C) the rate of geolgic processes remain the same over time, and the processes themselves remain the same.
