WebJul 1, 2024 · In response to climate change, global averaged oxygen concentration changes by −0.95 mmol m −3 in the upper 1000 m of the ocean from 1970 to 2010 (Fig. 4A and table S4). The reduction is attributed to lowered oxygen solubility associated with seawater warming and decreased oxygen supply due to ocean stratification ( 6 , 7 ). WebAssuming that the concentration of oxygen in the both waters is the same, why does a freshwater fish die if it is released in the ocean? Explain why substances such as sodium ions and chloride ions do not move freely across our cell membranes. In terms of concentration, which direction do solute molecules move during diffusion?
