The central nervous system.
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
Answer:
nucleotides is the right answer
