some people see bacteria as something that is harmful and that causes nothing but illness and infections. Bacteria can actually be helpful as well. It can provide vitamins to your body‚ help digestion‚ destroy bad organisms‚ help make medicines and also help out with the environment. In this research paper‚ it will describe two bacteria that are helpful and sometimes harmful to humans and the environment‚ which are E. coli and Lactobacillus Acidophilus. E. coli E. coli is the bacteria that live in

resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other bacteria. while the ones susceptible to the antibiotics die. This can be caused by unnecessary

Lecture 14 Lecture Gene Complementation in Bacteria In order to perform tests for dominance or for complementation in bacteria we need a way to make the bacteria diploid for part of the chromosome. To do this we need to consider a different extrachromosomal element: Ori T The F plasmid (length 105 base pairs) Tra genes There are some special terms to describe the state of F in a cell: F– refers to a strain without any form of F‚ whereas F+ refers to a strain with an F plasmid. F‚

Question: Suppose a meteor impact blows some extremophile bacteria from the Earth into the depths of a gas giant planet called planet X ‚ where they evolve into an intelligent species which practises physics. Do you think their physical theories would be similar to ours‚ and if so in what ways would they be likely to be similar? Your answer will necessarily involve some speculation‚ but make sure it involves some careful argument as well. Theoretical physics is one of many braches of physics that

approved in the United States; scientist‚ politicians and dairy milk producers have argued for or against its use. The truth is that many studies have been done and the lack of arguments and scientific proof about possible repercussions is the main reason why it is still legal. People still can decide which milk to buy; either treated cow milk or non-treated cow milk. The problem comes when people think that treated herd milk is a potential threat to their lives because they are not well

Cells Now we need to discuss CELLS. You’ve probably heard of cells‚ and may even know of a few‚ such as blood cells‚ nerve cells‚ or skin cells. What are these things called cells? Cells are the smallest living things. You’ll be learning a lot about cells in this course. For now‚ however‚ I’ll introduce you to just a few basic things about them. Cells are extremely tiny organisms that carry out all of the functions of life inside a thin layer of “skin” called (unimaginatively) the CELL MEMBRANE

Absract The aim of the prac was to identify and isolate Staphylococcus aureus and Eschericia coli in milk and salmonella in poultry.It was to investigate bacteriological quality of milk and poultry. Salmonella is areprobably the most important cause of food borne illness globally.Staphylocooccus aureus all cause food borne diseases if consumed in a contaminated milk. For milk a spread plate method was used and for poultry a streak method was applied using different Medias. All food contain a certain
