BRAINLIEST the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.

side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)

a)

Actual diameter = 0.007 mm

Diameter of scaled diagram = 2.3 cm = 23 mm

Formula to use:

Magnification = scaled dimension/actual dimension

Magnification = 23/0.007

Magnification = 3285.714... → x3286

b)

Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose

c)

i.

RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs

ii.

RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;

The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;

The small size also helps in being able to circulate the vasculature effectively and successfully

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
