Which of the following is a product of dehydration synthesis? a. water (H20)
b. carbon dioxide (CO2)
c. single sugars = monosaccharides

a. water (h2o)

Explanation:

In dehydration synthesis, the monosaccharides are joined by the hydrogen of one and the hydroxyl of another join. water is released. You can sort of think of it as dehydration means to lose water.

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
