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.

Chromosome because each chromosome is made up of DNA tightly coiled many times around proteins called histone that's support it's structure.
Each hemoglobin contains four iron-containing heme groups and four polypeptide chains. Four oxygen molecules can bind each Hb molecule.
True, four hemoglobin chains will contain one heme group, which will bind exactly one oxygen molecule. Since hemoglobin contains four globin chains with four heme groups, four oxygen molecules can bind to one hemoglobin molecule.
<h3>What is
hemoglobin ?</h3>
Blood-carrying protein hemoglobin (haemoglobin BrE) is derived from the Greek word haîma and the Latin term globus. (/hi-m-lo-bn, h-mo-/ abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein found in the tissues of some invertebrates as well as the red blood cells (erythrocytes) of practically all vertebrates (with the exception of the fish family Channichthyidae). The blood's hemoglobin transports oxygen from the respiratory system, including the lungs and gills, to the rest of the body (i.e. tissues). There, the oxygen is released, allowing aerobic respiration to take place and produce energy for an organism's metabolic processes. Every 100 mL of blood in a healthy person has 12 to 20 grams of hemoglobin.
