Describe the phases of the cell cycle. be sure to include the name of each phase and what is occurring within the cell during ea
julsineya [31]

Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.

 

<span><span>G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>

The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.

<span>Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.</span>

The endocrine system acts through chemical messengers called- -
3241004551 [841]


The best answer is D.

Hormones are chemical messengers  secreted mostly into blood and also extracellular fluid by specialized tissue of the endocrine system and affect the functioning of other tissues or cells.

Most hormones circulate in blood and come in contact with essentially all cells, but a particular hormone will only affect a limited number of cells, which are termed as target cells to that hormone.

A target cell responds to a particular  hormone because it bears receptors for that hormone.

For example the red blood cells have receptors for the  hormone called insulin which is produced by the pancreas. The red cells are able to take in glucose  when their receptors bind to insulin.
