Bacteria: a benefit or a hazard? Bacteria is something we are all reminded of on a daily basis by merely switching on our televisions where we are bombarded with advertisements for both ‘good’ and ‘bad’ bacteria. Contrary to the view of the past when only so-called ‘bad’ bacteria was ever talked about‚ so what has changed? This essay will address the facts about bacteria including methods used in identifying bacteria as well as looking at specific examples of how they can be both helpful and harmful

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

Jennifer Hauss March 4‚ 2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three
