Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.
Answer:
B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.
Explanation:
Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.
<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>
The correct option is B.
C. Nonexplosive, producing large amounts of lava
Answer:
what exactly do you need help with? like whats the question?
Answer:
Logically, if you are transporting an inhabitant of one aquarium to another, the conditions must be similar if not identical. When conducting experiments, the conditions must also be quite similar in order for tests to be accurate. Perhaps the inhabitants of the aquariums must need to same conditions in order to survive as well. I hope this helps!
