Answer:
a. His father's mother lacks a widow's peak.
Explanation:
To find out if you are homozygous or heterozygous, you need to find out the genotype of your parents. This you do by looking at their phenotype, their grandparents, uncles. After that it's easy to find out if it's homo or heterozygous. Of course, this need not even be done when it is a characteristic determined by recessive alleles, but in the case of a characteristic determined by dominant alleles, such as widow's peak (W), we must visualize the characteristic in the individual's country.
Since the man, shown in the question above, has widow's peak, so that your child knows if he is homozygous or heterozygous, just look at whether the trait is present in this man's parents. If his mother doesn't have widow's peak, we automatically know that the man is heterozygous, and that was his father's estate. However, if this man's mother has widow's peak and his father does, then the man is homozygous.
When you say small dissolved particles I am going to say endocytosis.
Turgor pressure makes a pressure on plasma membrane against the cell wall. The central vacuole in a plant cell is responsible for turgor pressure. When the vacuole loses water the cytoplasm "shrinks". The cell wall surrounds cell membrane of some cell types. If there were no cell wall around the cell, when cytoplasm gains the water, the cytoplasm will swell until plasma membrane burst.
