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.
Answer:
I believe a layer deep underground would have older things, because the ground could erode over time causing the fossil to sink into the ground.
