Answer:

The correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.

Explanation:

Bacterial cell wall is made up of peptidoglycan which contains NAG and NAM units joined together by β(1-4) glycosidic linkage but the cell wall of archaea are different from the bacteria and called pseudo-peptidoglycan.

The cell wall of archaea is also called pseudomurein which is also composed of two units, N-acetylglucosamine and N-acetyltalosaminuronic acid and these two components are joined together by β (1-3) glycosidic linkage which is different from linkage in bacteria.

Therefore the correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
Nina [5.8K]

Modelling refers to using a diagrammatic representation to present a particular event or biological activity.

The two maps shown are very good for representing/modelling mitosis.

Advantages

  • They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
  • The M phase was also clearly explained in the first diagram.

Disadvantages

  • The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
  • The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.
