Mitosis and meiosis are both cell division process except that the former is only done by somatic cells and the latter is done by gametes. In G1 phase or the growth phase of interphase, there is increase in cellular substance without DNA replication therefore DNA will be regarded as x. By the time when S or synthesis phase of interphase is finished, DNA replication is done therefore all phases that follow the S phase will have a DNA of 2x. In this case, the cell in metaphase of meiosis I has double the amount of DNA than the one in G1 phase because this cell already underwent the S phase. In meiosis, after the first division (meiosis I), there is reduction of genetic material into half (hence called reduction division) producing haploid cells. So a cell in the metaphase of meiosis II will have DNA half of that in metaphase of meiosis I thereby regarded as x.

<span>x DNA content in the G1 phase of a cell in the cell cycle is 2n. So 2n = x (given) Similarly the DNA content of the same cell in the cell cycle is 4n. This is equal to 2x (given). In the same way continuing with the lineage that is in the cell cycle, the DNA content will be 2n, which is again x.</span>

How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?
-BARSIC- [3]

Answer:

The correct answer is through anaerobic respiration in the cytoplasm.

Explanation:

Cellular respiration is of 2 types

1 Aerobic respiration Respiration that require oxygen to occur

2 Anaerobic respiration Respiration that do not requires oxygen.

During low oxygen level the body of runner keep up with the demand for energy by undergoing anaerobic respiration which includes Glycolysis.

  During anaerobic condition the functionally active body cells undergo glycolysis and with each glycolysis 2 molecules of ATP are generated which can some how boost the energy supply within runner"s body.

The diagram below represents a flower, the reproductive structure of some plants. Most
Evgen [1.6K]

Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

<u>The structure represented by the letter A in the diagram is the stigma.</u>

The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
