Answer:

option 1

Explanation:

In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.

Why would a vascular system be an adaptation for a plant on land?
Olin [163]

Answer:

Vascular have a system that is intricate and the plant can move water to distribute it to the whole plant. Vascular plants are able to grow bigger due to this ability. Example of this would be a tree or a flower Non vascular plants are usually small plants that are close to the ground.

Explanation:

Bryophytes, which evolutionarily precede tracheophytes, are plants that lack true vascular tissues by which to circulate liquids. These plants include mosses, hornworts and liverworts. Tracheophytes, which comprise about 93 percent of all land plants, all possess vascular systems that permit the internal circulation of liquids and nutrients.
