Answer:
Penicillin binds and inhibits bacterial enzyme DD-transpeptidase.
Explanation:
Penicillin is made up of 4 rings of β-lactam and acts by binding to DD-transpeptidase of bacteria. The DD-transpeptidase facilitates the cross-linking of the peptidoglycan cell wall of bacteria. This leads to malformation of the protective cell wall of the bacteria and causes it to lyze and die.

The type of front that is represented by this cross section is the occluded
<h3>What kind of front is an occluded front?</h3>
A warm air mass pushes on a cooler air mass (the warm front) and then another cold air mass pushes on the warmer air mass (the cold front). As cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
With this information, we can conclude that the type of front that is represented by this cross section is the occluded.

- Shrimps: Shrimps are favourite sea food among many people belonging to different areas. Hence, there population is declining due to which they need to be raised artificially.
- Salmon: The salmon is a kind of fish common to almost every nation. Hence, to meet the demands of people they need to be produced in maricultures.
