The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots
lactase persistence:
Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.
The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

Answer:
inactive proteins can be activated by phosphorylation
Explanation:
Proteins are regulated after translation by the non-covalent binding of small molecules. These molecules include amino acids or nucleotides. A change in the conformation and thus, the activity of the protein is usually achieved when this occurs.
Proteins could also be regulated by phosphorylation which is the addition of phosphate groups of specific amino acids on the protein.
The parent plant produced asexually because offspring from asexual reproduction are genetically identical to the parent.
Ok here we go:
Science starts with observing which leads to hypothesis, which is tested by experiments.
The other two i am not sure of. Hope i was a help to you. One thing you can do to figure out the other two is google: "what type of science includes medicine and envirnmental science", and do the same for the other one.
