4.5 DISCUSSION The bioluminescent bacteria grow well and produce good glowing in the SWC agar media compared to the LA agar media. In LA agar media‚ the production of light was very deem. It also took much time to solidify and the agar media was too soft and forms hole‚ therefore good streaking couldn’t be done. There might be error in the composition of the LA agar media ingredients. However‚ when SWC agar media used‚ there was good growth of bacteria and bright production of light. When comparing

For this experiment you will need 39 agar plates‚ sterile cotton swabs‚ a concentrated amount of Escherichia coli (E. coli)‚ three different levels of antibiotic (Ampicillin: 1mg‚ 5mg‚ and 10mg)‚ a bunsen burner‚ metal tweezers‚ an incubator‚ 27 broths‚ and a ruler which should all be provided through your laboratory. For the first generation‚ you will be using 12 plates. Three of the plates will be labeled G1 control‚ three of the plates will be labeled G1/1 mg‚ three plates will be labeled G1/5

Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3‚ 1.5g Potassium Phosphate Dibasic (K2HPO4)‚ 30ml 50% Glycerol‚ ~965ml water and 20g agar. The mixture‚ post- autoclave‚ was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle‚ and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

The Blues is a musical form and genre‚ which originated in South America within the African-American communities. It originated near the end of the 19th century‚ and was rooted from spirituals‚ work songs‚ field hollers (which are very similar to work songs‚ but some do not have lyrics)‚ shouts and rhymes. The blues form in jazz‚ rhythm and blues and rock and roll; and each is characterised by a specific chord progression‚ the most common being the twelve bar blues. The blues notes‚ are played or
