This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

conducted on 13th August 2008 in Machines Dynamics Laboratory. The experiment was conducted in groups of four‚ and was supervised by lecturer Mr. Mohd Azahari Johan. Conducting this experiment is for fulfilling the requirements of Applied Mechanics Lab (MEC 424). A pendulum is defined as body so suspended from a fixed point as to swing freely to and from by the alternate action of gravity and momentum. It is used to regulate the movements of clockwork and other machinery. Therefore‚ a compound

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

INTRODUCTION This scientific report is to discuss the results of an experiment being conducted on the effect that antibiotics have on the growth of bacteria. This will be done through the use of microbiology. Microbiology is a science in the department of biology‚ particularly microorganisms. These include; bacterium‚ fungi‚ protozoa‚ algae and viruses. This is an important subject to study as microorganisms can be found everywhere‚ covering all matters of different surfaces even including the human

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

We began the lab by first obtaining two sterile microcentrifuge tubes‚ one was label “GFP+” while the other one was “GFP–” because this one served as a control meaning nothing goes inside this one.

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion
