Answer: explained below
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed.
The concept to be used in order to determine the diameter of the second cell in the photograph is that of the ratio and proportion. The ratio of the first set of measurements should be proportional (equal) to the ratio of the second set.
Ratio of first set of diameters,
r = diameter of Cell A / diameter of Cell B
r = 12 micrometers/20 micrometers
r = 3/5
If we let D be the diameter of the cell B in photographs,
r = 3/5 = 15 cm/x cm
The value of x from the equation is 25. Hence, the diameter of cell B is 25 cm.
