An observation
A conclusion
A generalization
A hypothesis
Answer:
An observation
Explanation:
The statement; "After the gas was put into the jar, the limewater gradually changed to a milky white color." is an observation.
A observation rs to any event that occurs immediately after a particular chemical/ physical test is performed.
In this case, the test is that the gas was put into a jar containing limewater and an observation was made immediately

Explanation:
DNA acts as a map for living things.
Answer:
Explanation:
Heterochromatin in terms of accessible of the cell's machinery is termed as the region whereby the nucleosomes are tightly packed toghether such that the cell's transcriptional machinery is unable to access this regions. Examples of regions where this is found is at the centromeres, the telomeres and some other few regions in the chromosomes.
Euchromatin in terms of accessibility is the region wherein the nucleosomes are loosely packed such that the cellular processes machines is able to get access to the DNA.
The cell makes DNA in highly compatible state accessible by understood some epigenetic mechanisms such as modification of the histone tails. An example is acetylation; this allows addition of an acetyl group to specific regions on the tail of particular histones that allows for the unwrapping of the history from the DNA making them accessible. This is carried out by some enzymes known as histone acetyltransferases (HATs). Another example is phosphorylation: this does the same as acetylation.
