Answer 1

The false statements about Red Blood Cells (RBCs) are that RBCs are in the shape of a sphere, they survive on average about 220 days, and a normal RBC has a nucleus. RBCs actually have a biconcave disc shape, live for about 120 days, and lack a nucleus when mature.

Step-by-step explanation:

The question addresses false statements about Red Blood Cells (RBCs). Based on the information provided, the false statements are:

d) Normal RBCs are in the shape of a sphere: This is incorrect because normal RBCs have a biconcave disc shape, not spherical.

c) A RBC will survive on average about 220 days: This is false; RBCs live for about 120 days in circulation.

f) A normal RBC has a nucleus: This is false; mature red blood cells lack a nucleus.

On the other hand, statements a) RBCs are produced in the bone marrow, b) Mature RBCs are released into the bloodstream after approximately seven days, and e) RBCs' production is controlled by erythropoietin are all correct.
