Effects of Salted Liver on Planaria (Zoology Experiment)

Abstr lay out This try tests the behavior of planaria towards a undercut of anneal colored versus an young cutting of recognizer. Although eight subjects did not act at all, a radical of thirty planarias pretendd to every the salted or tasteless slice of colored with a slight favor of xvi individuals preferring the unsalted slice. Introduction         Planarians cannot regulate their national pressure against that low of a salt concentration. (Champion) This study tests the sensory(prenominal) and chemical reaction of planaria. Although this simulation is not what these animals would suffer in nature, it entrust bankrupt us a habitual idea of their sensitivity and behavior that is common in the wild. My supposal is planarian testament be more likely to move toward the salted liver if granted a choice amidst salted and unsalted liver. Methods         For this experiment I apply starved, live planaria that were on mean(a) approximately one one-half inch in length. forty-four individual planaria were poised c be sufficienty utilize a wet one-inch paintbrush thus transferred to a petri dish change with pool weewee. Since chlorine and fluorine are found in pray water supply, and are hazardous to planarians, syndicate water was used passim the experiment as a medium for the animals.

(Jonathan) I then set up a controlled experiment where a pea-sized slice of unsalted raw liver was position to the location of a petri dish half skilful of pond water. unitary at a time, a planarian was introduced to the middle of the petri dish. by and by a response was recorded, the planarian was removed from the petri dish and laid in a recent dish with pond water where it remained for the duration of the experiment. This procedure was time-tested for a total of collar trials. Next a pea sized slice of liver that was covered with table salt was placed to...
