Obviously if the bacteria need to be viewed with a microscope, they are extremely small. Darla likely does not have access to a microscope at her house, so using the macaroni and string, she made her own way of "seeing" the bacteria, but in a larger way.

D is false because macaroni wouldn't really show any patterns.
