Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.

During anaphase, homologous pairs of chromosomes are separated into their own haploid daughter cells.
<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>
