A patient sample will be analyzed. You are responsible to quantify the bacteria number. The dilution series shown in the Figure ( Dilution.jpg)  is prepared and 1 ml from each tube is plated. Plates were grown 24 hours resulting in colonies in each plate. Which plate you will use to quantify the bacteria in the patient sample? Why did you pick that plate?

Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."
