Answer:
Bacteriostatic
Explanation:
The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.
The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.

Answer: Rinsing with alcohol during the washing step stripped the bacteria off the glass slide.
Explanation:
The step that is being wrong in the whole experiment is that the student is washing the bacteria on the slide with alcohol.

This was the wrong step opted by the student if he finds any alternative solution to this then the bacteria can be observed in the microscope.
