Answer:

E.

Explanation:

A fetus is able to extract O2 from its mother's blood because fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin. Thus making it alot easier for the hemoglobin to bind to oxygen. This causes the oxygen-dissociation curve to move towards the left of the maternal oxygen-dissociation curve.

Answer:

E. Fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin.

Explanation:

Hemoglobin is a protein found in the blood which is responsible for binding to oxygen for efficient circulation to other parts of the body.

Fetal hemoglobin is usually at a high level and it’s produced around 6 weeks of conception. The fetal hemoglobin has a higher affinity for Oxygen than that of the maternal hemoglobin and it helps in carrying oxygen from the bloodstream of the mother to cells and tissues of the fetus.

Guppies, like all species, must be able to both sur<span>vive and reproduce in order to avoid extinction
