The graph gives the world population between 1950 and 2050. the numbers from today through 2050 are estimates. assume that the projections on the dotted (upper) line are true. what might be one result of the population change?

Basic needs such as food, water will be scarce.

Explanation:

As population increases there will be high demand for resources. The major nececities of life are food, water, and shelter. If the population exceed the available resources, the resources will be scarce and insufficient because the population has exceed the available resources.

When the population is normal food water will be much available because the population of people the will use the resource is equal to the available resources but when there is increase in population, the demand will outnumber the available resources and scarcity set in.

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.
