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).
Hence, all the other variables that could affect the DV to change must be controlled. These other variables are called extraneous or confounding variables. Extraneous variables â These are all variables, which are not the independent variable, but could affect the results (e.g. dependent variable) of the experiment.n an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. â¢ Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) â assumed to have a direct effect on the dependent variable.
