"B. organisms that use the same resource" is destined to cause the most competition between those organisms, since resources are scarce and almost always limited.
Answer:
The correct answer is "Histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction".
Explanation:
Histone acetyltransferases (HATs) are regulators of gene activation and deactivation, achieved by the transference of an acetyl group from acetyl-CoA to histones. HATs function by the premise that histones in general have a net negative charge that allow them to bind to DNA. Acetylation of histones, decreases their positive charge and weakens the histone-DNA interaction. Therefore, most of the times histone acetylation increases gene expression, because the acetylated gene is free from the histones and is able to be encoded.
During the phase of anaphase, each pair of chromosomes separate into two identical, independent chromosomes.
During the last phase of telophase the sisters chromatids reach opposite pole. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes and at each end. Hope it helped :)
