Under normal circumstances: a. Adult Hb binds to oxygen more tightly than Mb binds. b. Fetal Hb binds oxygen more tightly than adult Hb. c. Adult Hb binds oxygen more tightly than either fetal Hb or Mb binds. d. Mb has the lowest affinity for oxygen of the 3.

b. Fetal Hb binds oxygen more tightly than adult Hb.

Explanation:

This is because Fetal Hb needs to draw oxygen more efficiently from the blood stream of mother which is a very difficult task. The more affinity binds the oxygen from the blood stream that is already bonded with Hb of mother This is the main reasons it has higher affinity than that of an adult Hb.

Additionally, speaking of myoglobin. A myoglobin always has more affinity to bind oxygen that that of a haemoglobin molecule.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy
