Question

to test the impact of enzyme concentration, we will have 5 tubes. each tubes contains only half the enzyme as the previous tube. well make this by taking 5mls from tube 1 (containing 5ml 0.5% amylase solution and 5 ml water) and adding to tube 2 containing 5mls of water. well then take 5 ml from tube 2 and add to tube 3 containing 5 mls of water. this technique is called making a
a) demonstration control
b) water bath
c) serial dilution
d) calibrated rack

Explanation:

Serial dilution is a technique where a solution is diluted step - by - step, with each subsequent solution having a lower concentration. Here, each tube has half the enzyme concentration of the previous one by repeatedly taking a fixed volume from one tube and adding it to a fixed volume of water in the next tube.

Answer:

C. serial dilution
