1) They are caused by low salinity in the water.
2) Deep water currents are caused when nutrient rich water goes away from the water surface. The deep current water currents are important because they return the nutrient rich water back to the surface.
3) Waters that sink to the bottom of the ocean are cold, salty, and dense. Warm water on the other hand is not dense, so it floats to the surface.
4) Water that rises to the surface is warm and has a low level of salinity. It is also less dense than cold water.
5) <span>They are caused by low salinity in the water.
Hope this helps :)</span>
The Option C is correct.
- C) A reaction rate can be increased when the specific enzyme for a biological reaction is present.
By increasing the enzyme concentration, the maximum reaction rate greatly increases.
Conclusions:
The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
