The demand for environmental scientists and hydrologists is expected to increase because of a(n)
a increased demand for natural resources; need to create environmental laws to protect natural
resources for human consumption; need to develop air quality control systems for big business; need
to ensure proper disposal of human waste
b. increased demand for natural resources; need to enforce environmental laws and regulations; need to
analyze human impact on the environment and to invent ways to restore it; need to ensure proper
disposal of human waste
c. decreased demand for natural resources; need to analyze impact of invasive species on the
environment and to invent ways to preserve it; decrease of man-made reefs and their impact on
oceans; need to develop sanitation systems
d. decreased demand for natural resources; need to enforce environmental laws and regulations; need to
develop sanitation systems; need to create environmental laws to protect natural resources for human
consumption

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.

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.  

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
