Life Science Application : The major components of human blood are red blood cells, white blood cells, platelets and plasma. A typical red blood cell has a diameter of approximately 7 × 10-6 metres. A typical platelet has a diameter of approximately 2.33 × 10-6 metre. Which has a greater diameter, a red blood cell or a platelet
Solution:
Given, the major components of human blood are red blood cells, white blood cells, platelets and plasma.
A red blood cell has a diameter of 7 × 10-6 m.
A platelet has a diameter of 2.33 × 10-6 m.
We have to determine a red blood cell or a platelet which has a greater diameter.
The diameter of the red blood cell and platelet is expressed as scientific notation.
We know that the number expressed in standard form can be compared
The number with the larger power of 10 is greater than the number with the smaller power of 10.
If the powers of ten are the same, then the number with the larger factor is the larger number.
We observe that 7 × 10-6 is greater than 2.33 × 10-6
Therefore, a red blood cell has a greater diameter than a platelet.
✦ Try This: A sugar factory has annual sales of 3 billion 720 million kilograms of sugar. Express this number in the standard form.
