If the chemical enzyme pepsin was mixed with some proteins in a test tube in a laboratory, which of these outcomes would you predict? a)pepsin would probably not break down proteins in the test tube because enzymes cannot exist outside of the human body. b)pepsin would partially break down the protein molecules but would not work well due to the absence of dna in the test tube. c)pepsin would probably not break down proteins in the test tube because pepsin is designed to work at very acidic ph ranges. d)pepsin would break down the protein molecules equally well in the laboratory as in the human stomach since it is a stable chemical.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
