Answer:
The correct answer is - 6 chromatids.
Explanation:
Prophase is the stage in the cell cycle that is known for the condensation and disappearance of the nucleolus. In this stage chromosome become more compacts and the sister chromatids are still together and not separated. These sister chromatids are joined together with the centromere.
Centromere do not allow sister chromatids to move away and makes it intact. The number of centromere is the number of chromosme present in the prophase and half of the sister chromatids that means if there us 3 centromere than the number of sister chromatids will be 6.
The Ethics of Using Human Embryonic Stem Cells in Research. Assume for the sake of argument that it is morally impermissible to destroy human embryos<span>. It does not follow that all research with HESCs is impermissible, as it is sometimes </span>permissible <span>to benefit from </span>moral<span> wrongs.</span>
<span>Research partitioning is an adaptive evolution that when
species are have similar preys, they compete with each other and one species is
deemed to extinct in the process however if two species are of different preys,
then they can exist with one another. To exist with one another, organisms
belonging to a same species either compete for the resources or divide it
amongst themselves. This concept is important because it helps in diversified
ecology, where animals and plants of the same species co-exist and creates a
beauty with nature.</span>
