The absolute number of molecules of drug required to elicit a response
In areas where the walls are frequently washed, conduit should be mounted with a 1/4 inch air space between the wall and the conduit.
Conduits are the structures that are hollow and cylindrical like a pipe, channel or tube through which any material can pass. The material can be electrical wires, gases or even water. Therefore, the functions of conduits is to mediate the transport of materials from one place to another.
These conduits can be rigid or flexible depending upon their use and the material to be transported. Care should be taken when these conduits are embedded inside the wall that they are not very close and in contact with the wall otherwise the conduits may get damaged.

Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

"Marsh" ecosystem has the "greatest biodiversity".
Option: C
<u>Explanation</u>:
Marsh or Wetland ecosystem is highlighted as “biological super systems” as it is responsible to manufacture giant volume of meal that favors large amount of biodiversity, which is rich as rain forests and local reefs. The combination of important nutrients, shallow water and large primary productivity is basic source for Earth's food web. For example such food web is supported by birds, shellfish, fish, amphibians and insects. This ecosystem helps filtration of pollutants and soil runoff from the upstream sources which in return support river, ocean and bays in cleaning downstream.
