on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚ then they will regenerate stronger and faster. This is important because it could lead to faster regeneration for the animal and lead to bigger things such as finding a way to incorporate this to human regeneration. Many experiments have been researched

For the seventh experiment we will be performing different type of test to see how different chemical react with each other. The first experiment will be a demonstration the professor will give to the class. the first experiment you will be performing will include a test tube you will add a couple drops of dilute hydrochloric. you will add this to five little pieces of zinc metal. In next experiment you will performed you will put 2 ml of 3% hydrogen peroxide solution in a test tube .you will also

The purpose of Experiment 36 is to identify the anions present in an unknown solution based on the chemical reactions with various chlorides. In this experiment‚ Pb2+ was present in the unknown solution‚ while the presence Hg22+ is in doubt‚ and Ag+ is absent. To begin‚ the first part of the experiment involved analyzing the results from the experiment with the solution with equal volumes of AgNO3‚ Pb(NO3)2‚ and Hg2(NO3)2. Based on the results and observations obtained from the tests with the stock

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

Field Note 117: field radius growth is definitely not linear for linear control voltage increase. Ben sat back from the work bench and took several calming breaths. His sandwich sat on the test plate on top of the field projector array. It was a turkey club...the sandwich that is. The test plate was just a paper plate and the field projector array looked like a vintage ham radio and a movie projector had gotten very intimate. He couldn’t deny the results though. Little fella might have a touchy

The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted
