2. (2 pts) 02 Transport. The Arctic cod is one of the only vertebrates that does not have red blood cells or hemoglobin. Oxygen transport in their blood is possible without a carrier protein because: (a) They are really slow swimmers so they don't need much oxygen (b) Gas is more soluble at lower temperatures (c) Gas is less soluble in lower temperatures 3. (2 pts) Bohr Effect. (choose all that apply) Regarding the Bohr effect, it (a) Is an additional mechanism that tunes Oz loading and unloading in hemoglobin (b) Occurs in both hemoglobin and myoglobin. (c) Improves 02 binding to hemoglobin at high partial pressures of CO2. (d) Assists in unloading of O2 into tissues during high metabolic activity
