Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write a 1-page

Chemotherapeutic Agents of Control: Introduction: Chemotherapeutic agents are chemical substances used to treat various forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory.

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

Different kind of sand paper was used to grind and make smooth the spacmens and finally polishing cloth with diamond suspension was used to remove the extra scrachs . to diffrantiate the grain boundaries it was etched by nital solution. Finally the first observation was taken made by optical microscope and scanning electron microscope.

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

HUMAN PHYSIOLOGY REPORT DAPHNIA Aim The aim of this experiment is to investigate the effect of temperature and various substances on the heart beat of Daphnia‚ a water flea. Introduction Daphnia belongs to a group of small‚ freshwater crustaceans of the order Cladocera commonly called water fleas. They are very suitable for laboratory studies due to the nature of their transparent exoskeletons. Hence‚ it is possible to watch Daphnia hearts without dissecting them. Daphnia is ectothermic and

then placed the worm on the petri dish‚ with the spring water. Using a razor blade‚ the worm was cut in half into two sections of 6mm in length and 5 mm in length. The worms were measured using a ruler‚ and examined under a microscope. I tried to measure the worms under the microscope‚ next to the ruler‚ to obtain the best measurement but as the worms moved sporadically and were not always fully extended this proved tough to do. So instead it was necessary to just eye ball the measurement of the worms
