You freeze an enzyme and then warm it gently without passing the optimum temperature. What will happen to its activity A. The activity will speed up then decrease to zero
B. The activity will speed up
C. Activity will not be affected at all
D. There will be no activity

B. The activity will speed up

Explanation:

As temperature increases, enzyme activity increases (until is passes the optimum temperature)

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
