Final answer:
In hemocytometer counts, we use scientific notation to represent the number of platelets. The scientific notation for platelets would be in the form of 1.5 x 10^5 to 4 x 10^5 platelets per microliter.
Step-by-step explanation:
In hemocytometer counts, we use scientific notation to represent the number of platelets. Platelets, or thrombocytes, are actually cell fragments found in blood. According to the information provided, there are about 150,000 to 400,000 platelets per microliter of blood.
So, when counting platelets using a hemocytometer, the scientific notation would be in the form of 1.5 x 10^5 to 4 x 10^5 platelets per microliter.
