What is the difference between salinity and density. 5. how does this relate to the deep currents of the ocean?

Salinity is the concentration of salt dissolved in water while density is the ratio of mass over volume. In general, they are directly related - as salinity increases, the density of water increases as well. So in deep ocean, the dense water with higher salinity will sink below less dense water. The density difference will create flow between shallow and deep ocean water.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
