Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
Enzymes have an attachment site called the active site for the enzyme and substrate <span>to join.

Answer:
This process occurs in two stages: the light reactions and the Calvin cycle. Both stages of photosynthesis take place in chloroplasts. The light reactions take place in the thylakoid membranes, and the Calvin cycle takes place in the stroma.
Explanation:
all living organisms require energy to function.
When the capture starts to increase, the fish population
from 50 capture start to 100 capture start upsurges. At 200 capture start, though,
the population augmented in the beginning up until it touched 300 months where
it significantly dropped.
Numerous environmental factors can affect the populace of
fish. First, when there is a hurricane, the fish population will be affected
because the water will move and change.
Second, pollution. When individuals pollute the ocean, it
affects the fishes’ ability to live.
Lastly, when there is a lot of hunters that feed on fish. This
may cause many fishes to be consumed and their population will be reduced.
Is this science?? Also may I hv options.
