Answer:
B) decreased chromatin condensation
Explanation:
The addition of acetyl groups to the histone tails results in a less packed state of chromatin. The acetylation of multiple Lys residues in the amino-terminal domains of histones H3 and H4 reduces the affinity of the entire nucleosome for DNA. It occurs since acetylation reduces the total positive charge present on histone proteins. Histone proteins are positively charged and pack the negatively charged DNA around them. Therefore, increased acetylation results in decreased condensation of chromatin. The loosely packed DNA is accessible by RNA polymerase and transcription factors for gene expression.

Answer:
C. The maximum number of individuals of a particular species that an environment can support
Explanation:
Picture a graph, a logistic function, it's called, where it levels off at a horizontal asymptote in the positive quadrant. That's a visual representation of the carrying capacity. It's the maximum population the environment can support.
Clearly, there are limits to this. Scientists wonder what Earth's carrying capacity is, and if/when we will exceed it.
