What contribution to energy do carbohydrates make?

Most of the carbohydrates in the meals you consume are digested and crushed down inside glucose before accessing the bloodstream. Glucose in the blood is used up within your body's cells and applied to provide a fuel molecule called adenosine triphosphate (ATP) through a sequence of complex processes known as cellular respiration.

Explanation:

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

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
