What happends to an enzyme when it is exposed to temperatures above or below its optimal temperature

structure begins to break down (denature)

The particles with high kenetic energy

Explanation:

The first particles to evaporate from a liquid are those with the highest kinetic energy. When a liquid absorbs thermal or sound energy, its molecules speed up giving them higher kinetic energy. Typically, the particles or molecules at or just under the surface of the liquid escape into the gas phases first

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

c is the correct answer hope this !
