the prevalence of this disease is 1 in 365 african-american births in the us. estimate the genotypic frequencies in this population if the locus was in hardy-weinberg equilibrium.
based on your knowledge of this disease, do you think the population would be in hardy-weinberg equilibrium? why or why not? if not, what evolutionary force do you think would have the largest effect?

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
