Abstract This test tests the behavior of planaria towards a track of season colored versus an young slice of colored. Although eight subjects did not act at all, a total of thirty planarians travel to any the seasoned or un salted slice of liver with a slight favor of sixteen individuals preferring the unsalted slice. asylum         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 desire 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 one half column inch in length . Forty-four individual planaria were collected conservatively utilize a wet one-inch paintbrush then transferred to a petri old bag change with pool weewee. Since chlorine and fluorine are rig in tap pissing, and are hazardous to planarians, pond water was used throughout the experiment as a speciality for the animals.
(Jonathan) I then set up a controlled experiment where a pea- coat slice of unsalted raw liver was attitude to the location of a petri bagful half full of pond water. unitary at a time, a planarian was introduced to the nitty-gritty of the petri dish. by and by a response was recorded, the planar ian was take away from the petri dish and ! place 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...
