Prokaryotic cells
cell walls contain peptidoglycan
sensitive to traditional antibacterial antibiotic
the characteristics listed above describe the domain
a) archaea
b) bacteria
c) eukarya
d) monera

B). Bacteria

Bacteria are prokaryotic organisms. These have cell walls that contains peptidoglycan which establishes a structural framework of bacterial cell walls. The peptidoglycan is sensitive to traditional antibacterial antibiotic. As, these antibiotics are derived from bacterial strain which is more competent in nature against the infecting bacteria. Therefore, these antibiotics firstly degrade the cell walls of bacteria by degrading polymer chain consist of sugar and aminoacids present in peptidoglycan.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
