Arctic <u>cod</u> , fish that produces antifreeze proteins in its blood.
Answer:
Gills
Explanation:
In order to remove oxygen from the water, they rely on special organs called "gills." Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.

How Do Fish Breathe
<span>The
answer is more than 6 METs, MET measures by oxygen used by the body. Vigorous-intensity exercise is a physical
activity done with a large amount of effort. It is the intensity at which you
have a substantially higher heart rate and rapid breathing. </span>
I think if the whale population decreased the surface fish populations would decline due to reduced populations of algae. This can be simply explained by the fact that, if the whale population is decreased, it means that the nitrogen rich feces that is supply nutrients to the algae would also decrease and therefore decrease the population of the algae and as a result the population of of the surface fish would also decline.
