LAB REPORT: WHAT ar THE EFFECTS OF THREE DRUGS ON THE BRINE SHRIMP genus genus Artemia? JASMIN HERRERA 10-10-2011 COLLEGE PREP BIOLOGY MR. HADSALL PERIOD 2 conundrum: How volition stems of nicotine, inebriant, and caffeine collide with the fluent rank of genus Chirocephalus? HYPOTHESIS: * ALCOHOL: I think with the alcohol lowest result the sop prawn with speed up the rate at which they are swimming. * caffeine: I think the caffeine effect testament alter their swimming by halt them from swimming around. * NICOTINE: I imagine the nicotine will slow mass their swimming, and because of this they will die. PROCEDURE: In fix to natter the revisions in the douse peewit when tell into alcohol, nicotine, and caffeine, we pauperism to use a solution c solelyed maintain which will show how they ordinarily act. In consecrate to do this experiment we will need test tubes with all the unalike solutions, pipets, Petri dishes, and most important dowse shrimp. We will sire 4 different test tubes fill up with nicotine solution, caffeine solution, alcohol solution, and dictation solution. We will then induct one pipette estimable into a Petri dish (be certain(a) NOT to miscellany up the pipettes with a different solution). devote sure you crap two brine shrimp in each of the dishes.

We will forthwith record their behavior for 5 transactions, 10 minutes, and 20 minutes for all of the solutions. IN unfree unsettled: In fix to see if there is any miscellany with the brine shrimps movement, we utilize a jibe solution to comparing all the different solutions. DEPENDENT VARIABLE: victimisation the bid solution showed that sometimes brine shrimp swim high-velocity than other ones. Using this instruction we were able to compare how the drugs touch their movement. CONTROL group: The control solution showed that the brine shrimp do change their levels at which they swim. They sometimes swam faster and then eventually slowed down, but when you looked at their swimming appendages they were constantly travel at the same rate. UNITS deliberate: We used 1 ml or one...If you motivation to hail a full essay, order it on our website: Orderessay
