The answer is A because in the process of mitosis and meiosis chromosomes are single-stranded groups that are condensed to chromatin when the process of division of cells chromosomes replicate to make sure that the new daughter cells received the correct number of chromosomes
<span>Climax community=when the ecosystem reaches its mature state. After every disturbance, the ecological succession will culminate in the climax community. For example, ecological succession triggered by fires in Yellowstone Park culminates in pine forests. Pioneer species are the first species to colonize an area after a disturbance occurs. They reproduce quickly and survive in harsh conditions. For example, lichens.</span>

The Hardy-Weinberg equation is:

where p generally represents the frequency of the homozygous dominant population.
The q usually represents the frequency of the homozygous recessive population, and the 2pq term represents the frequency of the heterozygous population.
The mass percent of oxygen in Barium perchlorate is is 38%.
The molecular mass of Barium perchlorate (Ba(ClO4)2) is 336.2282 g/mol.
Percent composition of Oxygen will be = [(Molecular mass of Oxygen X 8)/ Molecular mass of Barium perchlorate] X 100%
= [(15.99 X 8)/336.2282] X 100% = 38%
