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

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

an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was determined in the experiment that the unknown was

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

Werner 05 March 2012 The Unknown Citizen By W. H. Auden Several conflicts are dramatized in The Unknown Citizen‚ the most prominent being: conformity of the middle class‚ government manipulation‚ and the loss of individualism to the standards of an average citizen. The speaker of this poem is non-traditional as the poem is‚ in fact‚ an inscription on a “marble monument erected by the State.” The inscription is dedicated to a “JS/07 M 378”—presumably‚ “The Unknown Citizen‚” although this term

A precipitate reaction happens when cations and anions of certain aqueous solutions react and combine forming
