Answer:
Glucose
Oxygen gas
Explanation:
Glucose is a non-metallic carbohydrate substance. It is the monomeric unit of the digestion of complex carbohydrate.
This compound is very important to all lives. The energy needed to power the activities in the body are derived from the compound.
It is made up of carbon, hydrogen and oxygen atoms.
Also, oxygen gas is used by animals for their metabolic processes. The gas combines with glucose to release chemical energy for use in the body. This molecule is purely made up of two atoms of oxygen that are covalently bonded together.
Anytime we breathe, we take in oxygen for use in our body
<h3><u>Answer;</u></h3>
b). Activation of an upstream guanine nucleotide exchange factor
<h3><u>Explanation</u>;</h3>
- <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
- The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.

During the S phase in the cell cycle, the chromosomes are replicated so that there are two copies. These copies are necessary so that each daughter cell created during the M phase will have an identical copy of the DNA.
Therefore, the answer is A: The DNA must be replicated.
The chromosomes joining, cell membrane expanding, and cytoplasm separating all happen during the M phase (mitosis).
