The Spot-Overlay Ames Test was used in the lab to find the mutagenesis of Diet Coke and ThermaFlu. Along with these substances three mutant strains of salmonella were also tested. TA 1535‚ TA 1537‚ TA 1538 all lacked the ability to grow the amino acid histidine unless reverted back by the potential mutagens. After the first week of testing‚ results showed that both of the potential mutagens‚ Diet Coke and ThermaFlu were in fact mutagenic. This was established if colonial growth was at least twice

Discussion Questions 1. Why do different metals have different characteristic flame test colours? The photons emitted during the test precisely match the quantum energy difference between the excited state and the ground state. For different elements the spacing between the ground state and the higher energy levels is different. So different elements have different flame test colours. 2. Most salts contain a metal and a non-metal. Look at the compounds we tested and determine whether it is

The tube that contained my unknown material was tube number twenty. I did a gram stain‚ oxidase test‚ and used three different medias to narrow down and identify my unknown organism. The first step I took in identifying was a gram stain. This gram stain would reveal whether my organism is gram positive or gram negative which would narrow my choices from fifteen options down to six. After completing the gram stain‚ my unknown was the color pink. This revealed my unknown as being gram negative.
