Answer:
There are 4.28×10^10 RBCs in the blood sample.
Explanation:
Concentration of blood = 5×10^6 RBC/10^-6 L = 5×10^12 RBC/L of blood
Volume of blood sample = 8.56 mL = 8.56/1000 = 0.00856 L
Number of RBCs = concentration of blood × volume of blood sample = 5×10^12 RBC/L × 0.00856 L = 4.28×10^10 RBCs
A way to measure plant growth. The issue with an experiment like this, is there is no way of telling if the plant would have grown differently if you had not added the extra fertilizers. To properly test this you must have "control" plants that would grow in the same conditions just without any fertilizer. You have to have multiple plants as subjects to get a good amount of data and then take the averages of each fertilizer and compare them that way.
(Just as a headsup if you are going to do this as a science fair project, don't use raw egg or unprocessed chicken poop. The egg turns the soil into rock and the chicken feces smells horrible and starts to mold. >< )
