The correct answer that would best complete the given statement above would be the first option. Coral reefs are built by a small organism called a polyp. The polyp creates the structure of the coral reef by building a CUP out of a calcium carbonate. The skeletons of these tiny corals s<span>ecreted by the lower portion of the polyp. Hope this answer helps.</span>

Answer: (1) Providing an optimized orientation of the substrate.
(2) Decreasing the ∆G in reaction.
(3) Excluding excess water.
Explanation: The active sites of enzymes increase the rate of reaction because they decrease the activation energy of the reaction,and the physical microenvironment provides an optimal orientation of the substrate relative to reactive functional groups while excluding excess solvent,such as water.
Although some active sites may have amino acids that form salt bridges with the amino acids from a substrate,not all do, so this is not a generic strategy of active site microenvironments

The type of microscope that <span>can produce three-dimensional images of a cell’s surface is the electron-scanning microscope. In this type, beam of high-energy electrons is focused to project the correct projection of the cells.  The projection of the cells are made up of signals of the surface.</span>
