top portion of the broth. Lab Results E. coli is MR+ because it does ferment glucose and the has a high acidity produced during the fermentation. E Coli is VP- because it does not make acetyl methyl carbinol‚ a neutral product. E. Coli produces more acidic products S. epidermidis is MR+ and is VP+ because it first changes to acidic products then is able to convert those acidic products into some neutral basic products so it gives both positive results.

Pets as carriers of soil inhabitant microbes into our homes GIZELL VASQUEZ Biology department‚ Pathogenic microbiology‚ Crosby Jones‚ Angelo State University‚ San Angelo‚ TX 76909 There are approximately 78.2 million owned dogs in the United States (1)‚ and according to the United States government the current population of the nation is 308.7 million. The portion of dogs to humans is 4:1. These statistics are of importance because these pets physiologically observed their environment by smell

Systems Biology Systems biology involves the study of an organism as one single system. Instead of analysing all the individual components that make up a cell‚ the cell is instead viewed as an interacting network of genes‚ proteins and biochemical reactions and these are studied as a whole. In 20th century‚ molecular biology was focused upon. A ‘reductionist’ approach was followed‚ in which the individual components‚ such as the cell nucleus or sugar metabolism‚ were studied in isolation. However

Conclusions At the end of Part A in this experiment‚ it can be determined that Sodium Chloride had the highest amount of conductivity tested by all groups. On the graph above‚ the data shows that NaCl (sodium chloride) held the highest amount of electrical conductivity for all groups and on the table it reads the highest numbers across its row. Also as seen in the data above‚ ethanol had the lowest amount of conductivity with sucrose‚ acetic acid‚ ammonia‚ and MgCl2 following in ascending order
