Scientists at a pharmaceutical company are exposing bacteria to new "prototype" antibiotics. during antibiotic treatment, many of these bacteria swell and eventually lyse. these new antibiotics likely target which of the following in bacteria? choose the correct answer from the following choices, and then select the submit answer button.
a) mitochondria and energy production
b) nuclei and genetic material
c) peptidoglycan synthesis and cell walls
d) ribosomes and protein synthesis

The correct answer is c) peptidoglycan synthesis and cell walls

Explanation:

The cell wall of bacteria is made up of peptidoglycan layers and lysis of cell occurs when antibacterial or antibiotic works on cell wall like in case beta-lactam antibiotic for example penicillin which causes cell lysis by ceasing transpeptidation reaction.

So this reaction is ceased, bacteria do not able to form new cell walls so holes are created in the cell wall. So due to these holes, the osmotic pressure inside the bacterial cell becomes high due to transfer of molecule inside it which cause cell lysis.

Therefore if new antibiotics cause bacterial cell swelling and eventually cell lysis then the new antibiotic is likely to target the peptidoglycan synthesis and cell walls.

the correct answer is d

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
