Membrane potential is determined by the:
A. difference in concentration of ions and charged molecules on the two sides of a cell's plasma membrane
B. concentration of cholesterol in a membrane
C. number and type of phospholipids present in a membrane
D. number and types of ion-channel proteins present in the plasma membrane of a cel

Explanation:

The plasma membrane is a type of selective membrane that plays an important role in regulating the molecules, ions and some other across the membrane. It is made of phospholipid bi layer. The potential difference occurs due to the diffrence between the ions concentration inside and outside of the membrane. The membrane potential plays an important role in the process of membrane polarization, depolarization, and some other conditions.

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
