Laura Lugo Group: Bianca Jonson Short lab report 10/4/14 Effect of household drugs on circulatory system of Lumbriculus Variegatus (blackworms) Hypothesis & justification part 1: In order to understand a little bit about the effects of common household drugs such as nicotine and caffeine on pulsation rate‚ an experiment was conducted with Lumbriculus Variegattus (Blackworms). In week 1‚ we observed the basal rate of three different worms‚ and then placed the same three worms on different concentrations

My name is Quinlin Beets‚ and I come to you from John Hopkins University where I study marine archaeology. The legend of Atlantis has been one of the oldest and most spellbinding of all the world’s mysteries. It has puzzled civilizations for many years. Civilization first heard about Atlantis in 330 B.C by Plato. Plato was a Greek philosopher. He wrote stories about Atlantis called “Timaeus” and “Critias”. He lived from about 428 B.C to 348 B.C. For two millennia no one thought about Atlantis.

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

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

“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
