Bisphosphoglyceric acid (BPG) is a byproduct of glycolysis released into the bloodstream when an animal's supply of oxygen is low. Like protons, it decreases hemoglobin's affinity for O2. The effect of high BPG levels would be that:
a. hemoglobin now binds more oxygen at low partial pressures than at high partial pressures.
b. hemoglobin picks up more O2 in the lungs than it would without BPG.
c. hemoglobin loses its cooperative binding of oxygen.
d. hemoglobin releases more of its bound O2 than it would without BPG.
e. hemoglobin holds on to more of its O2 than it would without BPG.

a. hemoglobin now binds more oxygen at low partial pressures than at high partial pressures.

Explanation:

I took regular Biology in 9th Grade, AP Chemistry in 10th Grade, AP Biology in 11th Grade, and DE (Dual Enrollment) Microbiology in 12th Grade. Currently majoring in Biology at the University of Michigan - Ann Arbor.

the answer is c cumulus. cumulus clouds can be seen on a gray and rainy day, because cumulus clouds create thunderstorms. give me brainliest if right.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
