Answer:
The correct answer is C) The compound is an allosteric inhibitor.
Explanation:
An inhibitor works in many ways, but this particular one binds to the allosteric site in the enzyme causing a decrease of the enzymatic activity. When this situation happens, the inhibitor doesn't bind to the active site, but it changes the enzyme's shape so it cannot work properly anymore.

The above factors are very essential to an hydrologist to predict floods though other factors such as topography, drainage among others are also inclusive to make the prediction rightly.
Answer:
No atoms are created or destroyed in chemical reactions.
Explanation:
Matter cannot be created or destroyed. When two reactants contact each other, a chemical reaction occurs which breaks the bonds between atoms and rearranges them, forming new bonds which transform them into the product. The same amount of atoms exists before and after the reaction.
Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil
