A structure-activity-relationship study A. considers the relationship of many enzymes based upon both their structure and activity.

B. makes a series of small structural changes to the drug then compares it to its activity with the enzyme.

C. isolates small portions of the protein to examine how their structure relates to their activity.

When an object falls through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance? (one word answer)

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

If two objects at different te,peraure are in contact with each other what happens to their temperature
