G6pd deficiency is an inherited condition in which the body doesn't have enough of the enzyme glucose-6-phosphate dehydrogenase, or g6pd, which red blood cells (rbcs) function normally. g6pd deficiency is most common in african-american males. many females are carriers. it is known that africa and the mediterranean basin are high-risk areas for the infectious disease malaria. researchers have found evidence that the parasite that causes malaria does not survive well in g6pd-deficient cells. how can you explain this? a )natural selection favors g6pd deficiency as compared to malaria. b) genetic drift is responsible for greater occurrence of g6pd deficiency in these regions. c) somatic mutations lead to g6pd deficiency in malaria-inflicted regions..

the correct option is option d

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.
