Answer:
c. Cold front
Explanation:
Cold fronts are bodies of air with cooler temperatures than the surrounding air. The general effect cold fronts have is that they cause a drastic change in the weather. This is because when they interact with the warmer air, they produce precipitation.
The storm most likely, came with an advancing mass of cold air, which caused the dramatic drop in temperature that was experienced. This is what is known as a cold front.

Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
