A nurse assisting a nursing student with medications asks the student to describe how penicillins (PCNs) work to treat bacterial
Mnenie [13.5K]

Penicillins disrupts bacterial cell wall synthesis.

<h3>How does penicillin affect bacterial cell walls?</h3>
  • Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
  • When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
  • β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
  • Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
  • They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.

Natural selection is the process by which favorable traits tend to increase in frequency over time.
Nana76 [90]

Answer: The statement is true

Explanation:

Natural selection, as its name implies refers to the choice of certain favorable traits such as resistance to diseases, bigger fruit size etc above lesser favorable traits such as easy susceptibility to diseases, small fruit size etc.

Hence, nature allows the traits that will help living organisms survive best in their environment to be passed down to new offsprings while it eliminates all other traits.

Thus, the statement is true
