Answer:
scientific theory: an explanation of an aspect of the natural world that can be repeatedly tested and proved to be a success every time.
Answer:
The correct answer is option 3.
Explanation:
Desmopressin is one of a man-made vasopressin drug that is used to replace the vasopressin of a low level. Desmopressin assists in regulated hike thirst and high reabsorption of water in the kidney that leads to too much urination.
Desmopressin is used to treat the case of bedwetting in children. The medication is used to increase the reabsorption in the kidneys of an individual.
Thus, the correct answer is option - 3.
when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.
<h3>What does molecular clock mean?</h3>
The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.
Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.
Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).
