I believe the answer is C. the need to acquire energy from other organisms
This is however an educated guess, but I hope this helps! :)
C.
In co-dominance both traits show up, and in incomplete dominance the two traits mix together.
So automatically A, B and D are wrong, since we can see both brown and white colors on the cow separately.
If it were any of those we wouldn't be able to see any of the traits alone they would be a mix.
Answer:Chromosones!
Explanation: Chromosones contain the DNA for your entire body.
Attachment of acetyl groups to histone promotes transcription.
This mechanism is known as histone acetylation and it is a part of gene expression. The lysine residues inside the N-terminal tail from the histone core of the nucleosome are the substrate for enzymes-histone acetyltransferase which transfer an acetyl functional group from another molecule. Acetylation removes the positive charge on the histones and thus decrease the interaction negatively charged phosphate groups of DNA. As a result, chromatin becomes more relaxed structure and transcription is promoted.
