Answer:
See details below
Explanation:
STEP 1:
We know already that the capacity to absorb oxygen of the body is not limited by the amount of oxygen available, but by the ability of hemoglobin to bind and transport O2 so Itamin O is useless. There is no an efficient way of extracting oxygen when we talk to GI tract but we know that is transport to our lungs without problems.
STEP 2:
It is required a dedicated O2 binding protein (hemoglobin) indicates that dissolved oxygen by itslef cannot attain the high concentration required. The use of some Vitamin O would make a difference in the amount of oxygen already present in the blood

Answer:
b. a fluid-mosaic of phospholipids and proteins
Explanation:
According to the currently accepted structure, the cell membrane is made up of two layers of amphipathic phospholipids in which proteins are embedded or present. The hydrophobic tails of phospholipids make the core of the membrane. These tails are not covalently attached to each other and are free to move laterally. Likewise, the protein molecules float in the fluid bilayer. This mosaic pattern is not static since the positions of the proteins in the bilayer are constantly changing. The fluid mosaic model to explain the structure of the cell membrane was given by S.J. Singer and Garth L. Nicolson in 1972.
