multiple choice question\nincreased gas diffusion across the rbc membrane and their ability to pass through small blood vessels can be attributed to \n\ntheir biconcave shape\nincreased cholesterol in the plasma membrane\nthe precipitation of hemoglobin along the plasma membrane\nthe flexible nuclear membrane
Answer
Brief Explanations:
Red - blood cells (RBCs) have a biconcave shape. This shape increases the surface - area to volume ratio, facilitating gas diffusion across the RBC membrane. Also, the biconcave shape allows RBCs to deform and pass through small blood vessels. Cholesterol in the plasma membrane affects membrane fluidity but not gas diffusion and vessel - passing ability in the way described. Hemoglobin is not precipitated along the plasma membrane, and RBCs in mammals lack a nucleus and thus a nuclear membrane.
Answer:
their biconcave shape
