Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.
Ans.
Chromatin molecules are made up of DNA and histone proteins. Modification of chromatin structure include covalent, post-translational changes in histone proteins, present in chromation. Acetylation and methylation are two important histone modifications that affect structure of chromatin molecules.
Acetylation involves addition of an acetyl group to histones that increases transcription of DNA by loosen the association between DNA and nucleosome.
Methylation involves addition of a methyl group to histones that results in condensation of chromatin molecule and thus, decreases transcription of DNA.
Both acetylation and methylation are reversible processes.
Many chromatin modifications are genetic, means they can pass from one generation to another generation, called epigenetic modifications.
Thus, options B), C), D), E), and F).
What are the options they gave you?
The part anti means opposed. Biotic is basically all the naturally occurring organisms. So an antibiotic would oppose an organism like a virus.

Explanation:
Primates are the third diverse group of mammals after rodents and bats. It is considered that it has diverged from other terrestrial mammals about 65 million years ago.
Defining and identifying the primates on the basis of certain anatomical and behavioral traits is not an easy task. There are almost 400 living species of primates are known.
