Answer:

The correct answer is A hormone local regulator synaptic signal.

Explanation:

Hormones are called chemical messengers because they carry chemical and biochemical information from one cell to another cell by a process called signal transduction.

      The hormonal signal transduction is generally mediated by endocrine signaling in which hormone is secreted from one gland and then is transported via the blood stream to binds to the receptor present in the target cell.

To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.

Thus, option "A" is correct.

What is Paramecium Contractile vacuole

"It is a sub-cellular structure (organelle) involved in osmoregulation."

<h3>What is a graph?</h3>

"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."

<h3>What does the graph in the given question depict?</h3>

It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.

But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.

Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.

Compare the properties of the parent and daughter cells in mitosis and meiosis and explain the reason for any differences.
katrin [286]
Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>
