How does histone acetylation affect chromatin?

a. it loosens the chromatin and allows increased transcription.

b. it allows dna to become resistant to damage.

c. it the histones have a greater affinity for dna.

d. it inhibits dna replication by making it more difficult to separate the dna strands.

e. it causes the chromatin to become more condensed in preparation for metaphase.

a. It loosens the chromatin and allows increased transcription.

Explanation:

Histone acetylation makes DNA resistant against damage. Histone acetylation loosens and make changes in the structure of chromatin and make it exposed to the different DNA binding proteins which will cause activation of transcription and other functions of cell

ur answer is e & d

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
