Answer 2

The correct option is, (c) 7 weeks.

• When a human donor gives a pint of blood, it usually requires 7 weeks for the body RESERVE of red corpuscles to be replaced.

The body RESERVE of red corpuscles.

• Red blood cells (RBCs), also known as red cells, red blood corpuscles (in humans or other animals without a nucleus in red blood cells), haematids, erythroid cells, or erythrocytes (from Greek erythros for "red" and kytos for "hollow vessel," with -cyte translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's main means of RBCs receive oxygen from the lungs or the gills of fish and release it into tissues while squeezing through the capillaries of the body.

• Hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red colour of red blood cells, is abundant in the cytoplasm of red blood cells.

Hence, When a human donor gives a pint of blood, it usually requires 7weeks for the body RESERVE of red corpuscles to be replaced.
