Which of the following terms describes the movement of water from the surface to the atmosphere?
lukranit [14]

Answer:

The answer is evaporation.

Explanation:

Runoff is not right because runoff is water that hits the surface of the earth, then runs down into natural bodies of water. It is not condensation either. That is because condensation is when cool water vapor comes into contact with humid, warm air causes water droplets to appear on the surface of what is containing the cool water vapor. Finally, precipitation is when water comes down from the atmosphere to the surface of the earth, therefore this is incorrect. Evaporation however is when water from the surface of the earth turns into water vapor and goes into the atmosphere. Therefore it is the right answer.

) You treat some cells with a proteolytic enzyme that is too large to penetrate the cell membrane (Set 1). Another group of cell
Advocard [28]

Answer:

Proten W

Explanation:

SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).

When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).

Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
