Answer
A typical bacterial cell diagram should include the following components: the cell wall, cell membrane, cytoplasm, DNA (indicating the nucleoid region), and plasmid. Each part should be clearly labelled for understanding.

Answer
A significant disadvantage of the overuse of antibiotics is the development of antibiotic resistance in pathogens. When antibiotics are used excessively, bacteria can adapt and evolve, leading to strains that are resistant to traditional treatments, making infections harder to treat.
