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<span>, 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, <u>4 chromosomes that enter meiosis II</u>.
</span>
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.
<span>A: Some energy will be used to do work and some will be lost as heat.</span>
D; because the cells dna is not in the nucleus
Answer :
Plants take in carbon dioxide from the atmosphere, water from the soil and light energy from Sun.
Photosynthesis occurs.
Oxygen and energy are produced.
There are 21% of oxygen in the atmosphere.
<span>On the left, they drain into the renal vein
which in turn drains into the inferior vena cava. By contrast, all the
lumbar veins and hepatic veins usually drain directly into the inferior vena cava.</span>
