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."

Suppose you are handling a P 200-1000 µl micropipette and while adjusting the volume you go over the 1000 range. What would happen and what needs to be done in such situation?
For investigating the effect of pressure (height of a column of liquid), a 50-mL burette wasused with a small length of rubber tubing fixed to the bottom on which a clamp could befitted to start/stop the flow of water (Figure 1). Effluent was collected in a beaker and meanflow rate was calculated (mL/s), and a stopwatch was used to measure how long it took for5 mL of liquid to flow out. For the subsequent sections of the practical, a 25-mL burette wasused, and the top was connected via rubber tubing to a 5-liter reservoir placed on theshelving above the bench. The tubing at the base was connected to the different flowmodules that comprised the different configurations of tubes to be tested. Figure 1: A. Theoretical set-up of the experiment. B.
