Would You Expect to Find More Dissolved Oxygen in Polar

question 59

• B)There would be more dissolved oxygen in the polar oceans because the colder oxygen would "sink" and dissolve into the water.
• C)There would be more dissolved oxygen in the tropical oceans because the heated oxygen molecules in the air would collide with and mix into the water.
• D)There would be more dissolved oxygen in the polar oceans because the solubility of oxygen in water decreases with increasing temperature.
