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: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Mallory Charland February 9‚ 2015 Mutations of E. coli Lab Report Advanced Biology Deducing Mutations of the Lac Operon of E. coli Abstract: In this lab we determined a possible mutation in unique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)

4. Results No hypotheses in the discussion section were necessarily falsified‚ but some broad statements were made. For example; “Culture conditions obviously influence the outcome of adaptive evolution.” This statement implies that they have extensive knowledge on all the different aspects of evolution. Many scientists today will admit that we do not fully understand evolution and all the factors involved. To say that the conditions ‘obviously’ influenced that outcome is too broad of a statement

Microbiology is the study of living organisms that are too small to be clearly seen by the unaided eye. The science of Microbiology dates back only to 200 years‚ yet the recent discovery of Mycobacterium tuberculosis DNA in 3000 year old Egyptian mummy reminds us that microbes have been around for much longer. Infact‚ Bacterial ancestors were the first living things to appear on Earth. The First observations: One of the most important discoveries in the history of Microbiology occurred in 1665

kingdom of microorganisms was brought into life 3 billion years ago. Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular. They first have been studied by Anton van Leeuwenhoek by the use of his own design microscope‚ in 1675. However

Mackenzie Skelton October 22nd‚ 2014 Journalism 350 Environmental Scanning Report Every year a new update for the iPhone is released and following that is the release of the actual new and improved phone‚ in this case the iPhone 6 and 6 plus. On September 24th‚ 2014‚ Apple launched the iOS 8.0.1. update‚ available to all phones‚ new and old. This update did the opposite of what it was intended to do by disabling cellphone service on an untold number of iPhones among some other small issues.

Artemia franciscana‚ the organism under study‚ is a well known generalist that has adapted it’s reproductive strategy to allow populations to withstand harsh environmental conditions (Gajardol et al. 2001). More specifically‚ A. franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A.

BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley between them. The organisms found on the south facing slope (SFS) slope of evolution canyon‚ which has harsher environmental conditions

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation
