Populations of organisms that exhibit a high degree of variation have a greater chance for survival than populations of organisms that show little variation. this statement is

always true.

usually true.

rarely true.

never true.

The answer is B. The answer cannot be always true in biology especially with regards to probability statistics such as those in this question. Nonetheless, increased variation in a population provides a wide base for selection pressures of natural selection to act upon. This way, there are high chances of adaptation of the population to an environmental change or calamity.

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.
