that people’s bacterial make up influence the amount of fat that one can store in the body. The second part of the article‚ The Bugs in your Gut‚ was about different types of bacteria in ones gut. These gut bacteria have a population in the trillions and they help curb ones appetite and keep off the fat pounds. The bacteria in skinny and obese people are at different levels. An experiment with a obese man who had gastric bypass surgery had a drastic change in the gut flora. A fluctuation different

transformation effect bacteria cells? -Our independent variable were Plasmids‚ the three genes on our plasmid are small and circular‚ self-replicating chromosome in bacteria. -Our dependent variable was florescent‚ ampicillin resistant bacteria. -The control was the plates were the one without plasmids which was LB/AMP/+PGLO‚ LB/AMP/-PGLO‚ LB/-PGLO. These threes represented nutrients and ampicillin‚ plasmids and arabinose. -The purpose to bacterial transformation is to insert DNA into bacteria to change

Garlic and Bacteria Inhibition Does garlic keep vampires away? You can’t prove it scientifically‚ but many people do believe that garlic is good for what ails you — among other things it helps to ward off infection. Emily Koch noticed that her mom‚ who eats garlic‚ has fewer colds than other family members‚ so she decided to see if the stories about garlic are true. You can get a look at her project display in the figure. Figure: Project display for “Garlic and bacteria inhibition.” Hypothesis

Disinfection is a procedure which destroys‚ inactivates or removes potentially harmful microbes- without necessarily affecting other organisms

CU254 Causes and Spread of Infection 1. Understand the causes of infection. 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – a single cell micro-organism that gets its nutrition from its surroundings and can only be seen under a microscope. Viruses - are disease producing agents far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy. Fungi – are included in the plant kingdom but are quite different

experiments. Test bacteria on any surface with the Surface Microbes Science Fair Projects Kit: after hand sanitizer‚ hands‚ disinfectant for example. You can use antibiotics to test the bacteria too. Anytime you want to test how many bacteria are On Top of a surface like a desk‚ skin‚ chicken‚ computer keyboard‚ bread dough‚ a hard piece of chocolate‚ cheese‚ inside of an animal’s cheek‚ etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit

gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls‚ which retains the crystal violet these cells are stained with. Gram negative bacteria stain red‚ because it has a thinner peptidoglycan wall and does

difference between bacteria‚ viruses‚ fungi and parasites? The difference between bacteria‚ viruses‚ fungi and parasites is: Bacteria Bacteria is a single celled organism‚ bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body‚ only 1% of bacteria is actually harmful. It ’s bad or infectious bacteria that cause illness as they rapidly reproduce and produce a toxin that kills or mutates cells‚ bacteria is also self sufficient

through the process of gene transfer. Gene transfer involves the insertion of a gene into an organism. The gene to be inserted is usually contained in a plasmid‚ which is relatively small‚ circular non-chromosomal DNA molecule typically found in bacteria. Once the plasmid containing the gene is inserted into the organism‚ it is absorbed into the organism’s own genetic code. After this occurs‚ the newly introduced gene begins coding for proteins‚ giving the organism a new trait. This process of genetic
