Answer:
e) S phase
Explanation:
The cell cycle is divided into various phases. These are in accordance with their order:
1. phase
In this phase, the cell grows in size and doubles its organelles. This phase is in fact a preparatory phase for cell division.
2.S phase
In this phase, the cell doubles its nuclear material (DNA). As cell divides into 2 daughter cells in mitosis, therefore it is necessary for cell to double its genetic material (DNA) which takes place in S phase. This genetic material is equally distributed among the daughter cells.
3. phase
In this phase, the cell further increases its store of proteins and organelles and prepares for the next phase i.e. M phase in which cell divides.
4.M phase
It consists of 2 processes i.e. mitosis and cytokinesis. In mitosis, the cell divides its genetic material (DNA) and in cytokinesis, the cell divides its cytoplasm resulting in 2 daughter cells.
phase
This is an inactive stage of cell cycle. In this stage cell does not divide further but remains quiescent. It performs its normal function in this phase. This phase is not a feature of all cells. Some cells like neurons (nerve cells) enter Go phase and remain there permanently whereas epithelial cells (cells lining body surfaces) do not enter Go phase and continuously divide. Cells enter Go phase after going through phase.
Back to the question,
If interval A contains half as much DNA as interval C then it implies that interval A is phase as in this phase of cell cycle, cell increases its size, and organelles but does not double its DNA content. It is further understood that interval C is phase as it contains double the DNA amount as in interval A. It can be understood that B interval is S phase, as in S phase cell doubles its DNA content and this phase occurs in between and phases.
Lets see...
Exhaustible Resources ~ An exhaustible resource is any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
Inexhaustible Resource ~ An inexhaustible resource is a source that will never run out, like, solar energy. So, Solar energy is out. Wind energy is out. Hydroelectric energy is out. Geothermal energy is out.
So, Biomass energy is not considered inexhaustible.

Available oxygen
Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.
<span>After
digestion, an amino acid not absorbed by the body and not used to build
proteins will first be subjected to removal from its amino group. If they are
not used for protein synthesis, amino acids becomes part of the metabolism
process. The body has the capability to create a subset of amino acids, also
known as non-essential amino acids because we don’t have requirement for them
in our diet. </span>
