Effects of Salted Liver on Planaria (Zoology Experiment)

Abstract This try out tests the behavior of planaria towards a man of season colored versus an young slice of liver-colored. Although eight subjects did non act at all, a total of thirty planarias travel to any the brininessed or un brine-cured slice of liver with a slight favor of sixteen individuals preferring the un salted slice. arrangeation         Planarians cannot regulate their midland pressure against that low of a salt concentration. (Champion) This study tests the sensory(prenominal) and response of planaria. Although this simulation is not what these animals would encounter in nature, it entrust give us a general thought process of their sensitivity and behavior that is common in the wild. My hypothesis is planarian testament be more likely to move toward the salted liver if given a choice between salted and unsalted liver. Methods         For this experiment I apply starved, live planaria that were on average approximately on e half butt in length. Forty-four individual planaria were collected cautiously utilize a wet one-inch paintbrush then transferred to a petri hit change with pocket billiards weewee. Since chlorine and fluorine are found in tap pissing, and are hazardous to planarians, pond water was used throughout the experiment as a mediocre for the animals.

(Jonathan) I then set up a controlled experiment where a pea- surface slice of unsalted raw liver was pip to the location of a petri attend half full of pond water. unitary at a time, a planarian was introduced to the affection of the petri dish. by and by a respo nse was recorded, the planarian was upstage ! from the petri dish and located in a fresh dish with pond water where it remained for the duration of the experiment. This procedure was tested for a total of trinity trials. Next a pea sized slice of liver that was covered with table salt was placed to...
