If the field of view is .45 mm in diameter and three cells can fit lengthwise across the field of view, how long is one cell?

150 microns

Explanation:

0.45mm is converted into microns by multiplying by 1000

0.45*100=450 microns

Therefore if 450 microns= 3 cells

                                      ? =1 cell

1*450/3= 150 microns

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
