Research analyzing the relationship between fitness and mortality indicates that the largest drop in premature mortality is seen between which two fitness groups? a. the average and excellent fitness groups b. the low and moderate fitness groups c. the high and excellent fitness groups d. the moderate and good fitness groups

Research analyzing the relationship between fitness and mortality indicates that the largest drop in premature mortality is seen between b. The low and moderate fitness groups. The low fitness levels in this group is the leading cause of premature mortality. The death of people without living their life to the average life expectancy of the total population is premature mortality. The low fitness groups face death of infants and aged individuals.

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.
