A Given Medium Can Be Either Selective or Differential but Not

Question

A given medium can be either selective or differential but not both.

Accepted Answer

A medium can be both selective and differential at the same time. Selective media allows the growth of only certain types of microorganisms, while differential media shows differences in the appearance of colonies based on their biochemical characteristics. Some media can be both selective and differential, allowing for the growth of a specific group of microorganisms while also differentiating between them based on their metabolic properties.
