A cell has 2n=8 chromosomes...how many chromosomes will this cell have in anaphase1,anaphase2,metaphase2?(meiosis)

1 answer:

8 0

The answer is 8 (anaphase 1), 8 (anaphase 2), 4 (metaphase 2).

Meiosis is a cell division which results in a reduction of the number of chromosomes in half and it consists of meiosis I and meiosis II.
Before meiosis I begins, the cell is diploid (2n) and there are 8 chromosomes. In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells, and after that, there are 8 chromosomes and 16 chromatids. After telophase I, there are, however, 4 chromosomes that enter meiosis II.

Meiosis II is similar to mitosis. So, in metaphase II there is the same number of chromosomes - 4 chromosomes. But, the chromosome number must double so in anaphase II there will be in total 8 chromosomes - 4 chromosomes at the one side of the cell and the 4 on the other side. After telophase II, there are 4 chromosomes.

The mass of some corn plants at the end of their growth period was 6 tons per acre. Most of this mass was produced from?

Aleksandr [31]

The majority of mass of any plant is produced from water from the soil and carbon dioxide with sunlight from the air. 6 CO2 + 6 H2O + sunlight ---> C6H12O6 + 6 O2 ... The gluclose (C6H12O6) is a simple sugar that becomes the biomass of the plant. Other minor contributors to the mass are from fertilizers (mostly N, P, and K) and minerals.
