The first level of dna organization in a eukaryotic cell is maintained by which molecule?
cohesin
condensin
chromatin
histone

The correct answer would be histone.

Explanation:

Histone proteins are the alkaline proteins mainly found in the nucleus of the eukaryotic cell.

It helps in packaging of chromatin fiber in the form of nucleosome.

The DNA molecule run around the histone proteins to form a bead-on-string conformation.

Five types of histones are involved in DNA packaging at this stage, namely: H1/H5, H2A, H2B, H3, and H4.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
