Please choose the answer that best completes the blanks of this sentence in the correct order. The plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.

streak, pour

Explanation:

The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
