I need help with these 4 questions! due NOW WILL GIVE BRAINLIST What effect did the sickle cell gene have on the people who were carriers of the mutation?

Why has the sickle cell gene persisted even when sickle cell anemia is so debilitating?

What are the odds that the child of parents who each carry one normal gene and one sickle cell mutation gene will have sickle cell anemia?

What are the odds that a child of two carrier parents will also be a carrier and, thus, be protected from malaria?

i need an image of the diagram

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.
