What causes air movement between the land and the ocean? A. radiation current

B. convection current

C. connection current

D. conduction current

B.convection current

Explanation:

Convection current causes the movement of air between the land and ocean.

Convection is a form of heat transfer prominent in fluids, liquids and gases.

In this case, temperature and density differences plays very vital roles in moving heat.

The surface is a good conductor of heat and the air around it heats up. This makes the is air less dense and it rises. The air above is colder and denser and it replaces the rising warm air. The continuous cyclic exchange sets up convection currents.

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
