Part I: Pre-Lab Diffusion/Osmosis Pre-Lab Introduction: Dialysis tubing allows molecules to diffuse through microscopic pores in the tubing. Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences. For problems‚ show equations and work with units and appropriate significant figures. Part IA: In the following

In the BIO 14 Lab‚ the organismal system used for the last of three labs this semester is the Mimosa pudica plant. In these three weeks the stimulus-response of these plants will used to conduct experiments on the phenotypic plasticity of Mimosa pudica. Phenotypic plasticity is the ability of an organism to change its phenotypic traits in response to changes in the environment. And while very beneficial in some ways such as by allowing organisms to adapt to a changing environment quickly‚ it also

Environmental Systems Bio-cylinder Lab Report Planning: The question that we‚ as a class‚ were trying to answer was: How long can the organisms survive within a sample-closed ecosystem? To answer this three separate classes had the opportunity to create their own bio-cylinders‚ place a specified number of organisms‚ seal it‚ and observe the cylinder for however long the organisms were able to survive. Each class made small modifications to the number of fish and snails that placed within the

In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

“Comparing Average Rates of Respiration in Mealworms in Light and Dark Environments in a Manometric System” Mohammad Rafi 213552179 BIOL1000 LAB REPORT Oct 28‚ 2014 Hypothesis The biological hypothesis for this lab experiment was that the rate of respiration in mealworms would decrease in mealworms that were exposed to a dark environment compared to those mealworms that were exposed to a light environment. This hypothesis was based on the fact that oxygen levels tend to decrease in

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100‚ 200‚ and 300 years. By manipulating parameters that influence natural selection‚ the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size
