Nicole Reardon Biology 1520‚ Section P2 Effects of penicillin and temperature on the growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative

Band Leadership Audition - Short Essay Questions 1. As a leader‚ how will you encourage and motivate other individuals? Motivation is achieved through praise. If students are complimented on their effort‚ they will often perform higher and have a higher sense of motivation. However‚ blind praise yields spoiled results. I will expect excellence out of my peers. I will make sure to voice those expectations‚ and help my peers set reasonable short-term goals to accomplish the exellence we strive

An Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

Out Of Band Signaling There shall be three Out Of Band (OOB) signals used/detected by the Phy: COMRESET‚ COMINIT‚ and COMWAKE. COMINIT‚ COMRESET and COMWAKE OOB signaling shall be achieved by transmission of either a burst of four Gen1 ALIGNP primitives or a burst composed of four Gen1 Dwords with each Dword composed of four D24.3 characters‚ each burst having a duration of 160 UIOOB. Each burst is followed by idle periods (at common-mode levels)‚ having durations as depicted in Figure

to assume that the larger the asteroid‚ the larger the crater. While this is partially true‚ it is not the only factor that controls crater size. This experiment will be exploring the asteroids speed and how this effects a craters size. Aim This scientific experiment was conducted to find how the impact speed/energy of an asteroid affects the diameter/size of a crater. Method A golf ball was dropped into a bucket of sand from heights ranging between 1-5 meters. For every height‚ the golf was

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

Lap-Band System vs. Gastric Bypass Bibliography I choose to do my research on the Lab-Band system. It is the new weight loss surgery that is taking over. The process makes losing the weight a slow process and very minimally invasive. Hospital stays are shorter and the recovery process is faster. History of the Lap-Band System

Marching and Concert Band Marching band and concert band have two completely different concepts. However‚ many high school students consider the word band as being able to play some kind of musical instrument. Being a five year marching band member and playing in concert band for seven years‚ I feel as if I know the difference between these two activities. One of the main differences between marching and concert band is the mental process one must go through to memorize the music and the steps on

Can tegu lizards maintain an elevated body temperature during their reproductive season? Experiment: Dr. Glenn Tattersall and a team of researchers in Rio Claro‚ Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae)‚ by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over
