Answer:
I.
Explanation:
The woman's father has haemophilia so his genotype must be XhY, so his daughter can only have the following genotype: XHXh. Her husband is not a haemophiliac so his genotype must be XHY. There is a 50% chance that the mother's gamete has the recessive allele for haemophilia. If she has a son that son will have a 50% chance of getting the Xh. This also applies to daughters, but they will get the normal allele XH from their father so the daughter will have a 0% chance of developing haemophilia.
The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
The right side of the heart sends blood out to the lungs to become oxygenated and that oxygen-rich blood comes back to the heart on the left side. Then the left side of the heart pumps the oxygenated blood to the rest of the body.
