This is where the stomach empties partially digested food into the intestine, and the pancreas releases digestive enzymes into these contents. The central section of the pancreas is called the neck or body. The thin end is called the tail and extends to the left side.
for the experiment to be accurate, there is one independent variable (the thing you change), and one dependant variable (the thing changed by the independent variable and what â¦ you measure).
The control variables are all other variables than the experimental variable. Example: If you want to know how speed affects gas mileage, then speed is the only vari-able that should change. The car, tires, road, wind speed need to stay the sameâbe controlled. They are control variables. Experimental Variable âthe vari-able that you are studying (changing) in an experiment.
