Answer:
The characteristic of water-soluble hormones are:
1. They dissolve in water and do not dissolve in fat or oil
2. They are produced from amino acids that are soluble in water
3. They will be unable to pass through cell membranes that have fatty molecules
4. They are receptor-specific. That is they bind to a receptor that fits them on the target cell.
<u>Option A</u>) A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.
<h3>
What mutation causes lactase persistance?</h3>
A mutation in a single nucleotide, in which thymine replaces cytosine, in the region that controls the expression of the lactase gene is what causes the lactase persistence trait.
This mutation first occurred in Hungry, and then it spread out to other regions of Europe, Africa, and Asia.
This mutation allowed humans to digest milk during adulthood.
According to this information, we can assume that the correct option is A). A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.

Answer:
1.) 80 chromosomes in each of the daughter cells. 2.) Two daughter cells are produced. 3.) The daughter cells are identical.
Explanation:
1.) In mitosis, a parent cell divides to form two daughter cells through the mitosis phases creating the same amount of chromosomes for each daughter cell as the parent cell.
2.) The parent cell divides to form the two daughter cells in cytokinesis.
3.) The daughter cells are direct replicas of the chromosomes in the parent cell unless there is a mutation in the DNA when it is being copying.
