A streak culture was performed on a Tryptic Soy Agar Plate for isolation and purity and then incubated at 37 degrees Celsius for 24 hours. A gram stain was performed to determine whether the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed

Willow changed her perspective on things because before Mai just went with things and didn’t question them but since Willow she saw things more clearer and saw what the world could be instead of what it is.

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s

since they are readily carried about by air currents. Septa = hyphal cross walls which divide the filaments into separate cells. Petri Plate (dish) = a special covered dish in which mold is cultured. Medium = a solid nutrient used for culturing. Agar = a non-nutrient thickening agent which is thicker than gelatin but still quite soft. Smear = a thin film of microbial cells on a microscope slide. Fixing = passing the smear through the flame of the laboratory burner three times in rapid succession

CHORUS OF THE PEOPLE IN THE LANE The tongues in the lane clack-clack almost continuously‚ going up and down the full scale of human emotions‚ human folly‚ ignorance‚ suffering‚ viciousness‚ magnanimity‚ weakness‚ greatness‚ littleness‚ insufficiency‚ frailty‚ strength. They clack on the street corners‚ where the ice shop hangs out a triangular red flag‚ under the shadow of overhanging building that lean precariously‚ teetering across the dingy chasm of the narrow lane.

the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused at a faster rate of 24.8 cm and formed a white smoke near the HCl end that had the molecular weight of 36 g/mole. The water agar-gel setup was made up of a petri dish containing
