Average time which requires to obtain result are 18- 24 hours for rapid system.Antibiotic sensitivity test can help in finding that which antibiotic is more effective in treating infection accordingly.

Antimicrobial susceptibility test is very significant bacterial isolates and there goal of testing is to detect possible drug resistance in common pathogen to assure susceptibility to drug of choice for particular infections.

Answer:

15 hours and 40 minutes

Explanation:

The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.

Interphase: 15 hours

Prophase: 20 minutes  

Metaphase: 20 minutes
