Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.

Hypothesis
Fact: Something that is always the case (ex: The plant has grown)
Hypothesis: Something that is based upon some evidence (If the plants grows in sunlight, then that's the only thing it needs to survive
Law: Something that explains why something happened (The plant grew while in sunlight, so it needs the sun to survive)
Theory: A hypothesis that has been proven through evidence (When I only fed the plant fertilizer, it didn't grow, but when I fed it fertilizer and gave it sunlight, the plant blossomed more and more)

Answer:
rate of ripening
Explanation:
Every experiment that an experimenter carries out includes a dependent variable and an independent variable.
A dependent variable is a variable in the research which depends on another. It is dependent and its value changes if the independent variable changes.
In the context, a scientist investigating the rate of ripening of tomatoes with relation to the light and its effect on tomatoes. Thus the independent variable here is the intensity of light and the dependent variable is the ripening of the tomatoes.
