As humans grow, their bodies change. Which of these statements explains how humans grow? A. cells from a cell wall
B. cells undergo mitosis
C. cells increase in size
D. cells merge to become larger

B. cells undergo mitosis

Explanation:

Many organisms increase in size over time. However, it is not because the cells are increasing in size. It is because of mitosis, in which the cell are multiplying in amount, or increasing in number.

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.
