Answer:

Mutation

Explanation:

The main cause of variation within a population is usually through genetic mutation.

Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.

Most times, environmental influences are paramount to causing genetic mutation within a population.

Other times, it might be due to competition and some other internal factors.

Mutation can be transferred from parents to offspring in most cases.

<h3><u>Answer;</u></h3>

peptidoglycan

The molecular basis of the Gram stain is the amount of<u> peptidoglycan</u> in the bacterial cell wall.

<h3><u>Explanation</u>;</h3>
  • Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
  • Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
  • The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.
