Detailed explanation-1: -So when the red blood cell is drawn 100 times larger than its actual size, the drawn size is 8 * 100 = 800 m = 0.8 mm.
Detailed explanation-2: -(b) The average diameter of a real red blood cell is 0.008 millimetres. On the photograph, the diameter of the red blood cell is 100 millimetres. (c) Some blood capillaries have an internal diameter of approximately 0.01 millimetres.
Detailed explanation-3: -The size of RBCs range from 4-7 mm, the largest erythrocyte is found in the dog (7mm) and the smallest in the goat (4 mm).
Detailed explanation-4: -A typical red blood cell has a diameter of approx 7×10−6metre. A typical platelet has a diameter of approximately 2.33×10−6 metre.
Detailed explanation-5: -A red blood cell is approximately equal to the plant cell in size. Given: The size of a red blood cell is 0.000007 m and the size of a plant cell 0.00001275 m.
