<span>Archaeas and Bacterias are both Prokaryotes. Both used to be classified in Monera kingdom, but later genetists found that they have actually very different genes, despite they both have a similar metabolism. So they think they have a totally different evolutionary origin and they decided to classify them in 2 different domains. The other domain, Eukarya, includes every other organism (all the ones who are not Prokaryots), which are: plants, animals, fungi and protists.</span>
I believe the answer is D. The organisms would require an outlet for their waste.
Animals<span> give off carbon dioxide which </span>plants<span> need to make food and take in oxygen which they need to breathe. </span>Plants<span> cells have cell walls and other structures differ from those of </span>animals<span>. </span>Plants<span> have either no or very basic ability to sense. </span>Animals <span>have a much more highly developed sensory and nervous system. thats how they're different

Answer:
b. conversion of the beads on a string to the 30 nM fiber
Explanation:
Histone acetylation process adds an acetyl group to lysine amino acid in histone protein. Lysine is usually positively charged and thus is able to make strong bond with negatively charged DNA molecule. When acetyl group is added to lysine, its positive charge is removed. The bond between histone and DNA weakens and the whole structure becomes more open, loose and transcriptionally active.
Beads on a string is formed by wrapping of DNA around histone proteins. This structure further condenses into 30nm fiber leading to more compact and tightly packed chromatin structure. Since histone acetylation loosens up the chromatin, this process does not take place here.
