Answer:
The correct answer is: B. pure culture.
Explanation:
- Sputum sample contains varied types of bacteria.
- When this sample is cultured on a growth medium all the different types of bacteria grow on it.
- A single distinct colony of bacteria is formed from by multiple divisions of a single bacterial cell.
- In the given growth medium distinct colonies of bacteria are formed.
- Each such colony is formed from a single bacteria.
- When such a single distinct colony is inoculated in a separate medium and bacteria is grown in that, then a Pure culture of bacteria is generated.
- A Pure culture can be defined as such a culture which is comprised of single type of bacterial cell, formed from a single bacteria.

Answer:
Explanation:
The total solution formed after mixing the components will be
20 μl + 20 μl + 40 μl + 120 μl = 200 μl
The smallest size tube that will hold the entire reaction is:
Firstly convert 200μl to ml
1000 μl = 1 ml
200 μl = X
X = 200 x 1/1000
X = 0.2 ml
The smallest size tube (from the options provided in the question) is 0.25 ml.
The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.
The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
