Biologists estimate the size of a specimen at high magnification by ____
|
|
using a ruler and measuring it
|
|
|
calculating the field of view then counting how many of the specimen would fit across
|
|
|
calculating the total magnification
|
|
|
making a guess based on prior knowledge
|
Explanation:
Detailed explanation-1: -Divide the number of cells in view with the diameter of the field of view to figure the estimated length of the cell. If the number of cells is 50 and the diameter you are observing is 5 millimeters in length, then one cell is 0.1 millimeter long. Measured in microns, the cell would be 1, 000 microns in length.
Detailed explanation-2: -*To figure the length of one cell, divide the number of cells that cross the diameter of the field of view into the diameter of the field of view. For example, if the diameter of the field is 5 mm and you estimate that 50 cells laid end to end would cross the diameter, then 5 mm/50 cells = 0.1mm/cell.
