Question

question 4 (1 point) saved which formula should you use to calculate the size of one cell under the microscope? cell size (μm) = field diameter (μm) + number of cells across cell size (μm) = field diameter (μm) ÷ total number of cells across cell size (μm) = total magnification × field diameter (μm)

Explanation:

Step1: Recall cell - size calculation concept

To find the size of one cell under a microscope, we divide the field diameter by the number of cells across.

Step2: Identify the correct formula

The formula for calculating the cell size (in $\mu m$) is Cell Size ($\mu m$) = Field diameter ($\mu m$) $\div$ Total number of cells across.

Answer:

Cell Size ($\mu m$) = Field diameter ($\mu m$) $\div$ Total number of cells across
