Answer:
0.05 mg/mL ( B )
Explanation:
Given data:
20 mg/ml starch
2% solution = 2g of solute is in 100g of solvent
<u>Determine the new concentration in mg/ml </u>
Dilution equation = C1V1 = C2V2
new concentration ; applying the dilution factor
dilution factor = 1 : 400 ; ( 2 /400 )g = 0.005 g of solute is present in every 100 mL
∴ new concentration = 0.00005 g / 1 mL * ( 1000 mg / 1g ) = 0.05 mg/mL
Hello!
During replication, DNA sequence is maintained in the new strands
The reason for it is the action of DNA Polymerase. This is an enzyme who has the function of "proofreading" the DNA sequence to ensure that all nucleotides are in the right order. This process is so accurate that an incorrect base is introduced every 10⁹-10¹⁰ bases.
