Yes, it could be.
But there are also many other things it could be the result of.
<u>Answer:</u>
The sequence of the bases in DNA is most important because it provides the instructions for the traits of an organism.
<u>Explanation:</u>
- 'Deoxyribonucleic Acid (DNA)' is an instruction carrier. DNA stores the information and passes it from one generation to another.
- It stores all the information that helps in growth, development and different characteristics developments.
- So, the 'sequence of DNA bases' is important to be transferred during the reproduction that transfers the characters from parents to children.
Answer:
B. MacConkey is both a differential and a selective medium.
Explanation:
Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.
For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.
Differential media allow to differentiate between selected microbes by visual observation.
For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
