Answer:

b. aggregate abnormally to form fibers and cannot adequately carry oxygen

Explanation:

The sickle cell hemoglobin is an abnormal form of hemoglobin. As the sickle cell hemoglobin release oxygen to the interstitial fluid, it forms long, stiff, and rod-like fibers. These aggregates of hemoglobin tend to bend the erythrocyte into a sickle shape. The sickled erythrocytes rupture easily and do not move easily through blood vessels. Sickled cells tend to stick together and form clumps which in turn cause blockages in blood vessels. Therefore, the presence of sickle cell hemoglobin adversely affects the ability of RBCs to carry oxygen.

the fish need the oxygen for respiration, breathing through their gills.

Explanation:

The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.

more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.

temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.
