The best answer would be:
A. The stage during which the cell carries out normal cellular functions and makes copies of its DNA.
If you'd like to know more about it, read on:
The cell actually spends most of its life in this phase of the cycle. This is the point where the cell grows and makes copies of its DNA in preparation for cell division.
Interphase is divided into 3 steps:
G1 phase - the cell grows larger and it makes copies of its organelles. (also known as the first gap phase)
S phase - the cell synthesizes copies of its DNA that is found in the nucleus.
G2 phase - it grows more and makes proteins in preparation for cell division. The cell even reorganizes its organelles in this phase.
Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):

Answer:
Species accumulate their unique features rapidly, then change little for the duration of the species.
Explanation:
Cloning will not lead to designer babies because clones are a complete copy of the person being cloned. The clone would need to be genetically modified to be considered designer
The immune system has many kinds of white blood cells to fight infections. HIV finds the white blood cells, called CD4 cells. But with cancer the white blood cells are being killed off.
