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.

2)Keep more fruits, low-fat dairy products (low-fat milk and low-fat yogurt), vegetables, and whole-grain foods at home and at work. Focus on adding healthy food to your diet, rather than just taking unhealthy foods away. Try to eat a family meal every day at the kitchen or dining table.
3)Biomacromolecules are large biological polymers, such as nucleic acids, proteins and carbohydrates, that are made up of monomers linked together. For example, proteins are composed of monomers called amino acids.
4)The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed
5)Cellular metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. Cellular metabolism involves complex sequences of controlled biochemical reactions, better known as metabolic pathways.
6)Sugars, such as galactose, fructose, and glycogen, are catabolized into new products in order to enter the glycolytic pathway.
