The identify of the four DNA nucleotides is based on b) covalent bonds.
When a cell is immersed in a hypotonic solution, the volume of the cell will rise as it will cause will be a net inflow of water inside the cell. If the concentration of solutes outside the cell is lower as compared to inside the cell and when the solutes are not able to cross the membrane, then the solution is called hypotonic to the given cell.
The ability of an extracellular solution to induce water to osmotically enter or depart a cell is known as tonicity.
Three terms—hypertonic, hypotonic, and isotonic—are employed in order to evaluate if a solution would cause water to move into or out of a cell:
- If a cell is immersed in a hypertonic solution, it will lose volume because there will be a net flow of water out of the cell.
- A cell will shrink if it is submerged in a hypertonic solution because water will escape the cell.
- Since there is no net water movement in an isotonic environment, the cell's size remains constant.
- A cell will absorb water and swell when it is exposed to a hypotonic environment.

Answer;
-Hemophilia
Explanation;
-Hemophilia is a rare disorder in which an individuals blood doesn't clot normally because it lacks sufficient blood-clotting proteins (clotting factors).
-Hemophilia is an X-linked genetic disorder, which means that it's passed from mother to son on the X chromosome. If the mother carries the gene for hemophilia on one of her X chromosomes, each of her sons will have a 50% chance of having hemophilia.
