Kristen Magliola 9/9/13 BIO: 414L Lab Report: SOC Medium I. Purpose: To make liquid and solid media for microbial growth II. Background: There are four different types of media used to grow microbes. They consist of Enriched media‚ Nutrient media‚ Selective media‚ and differential media. Enriched media is a growth media supplemented with complex biological molecules. This type of media is used for blood‚ coagulated blood‚ amino acids‚ etc. Nutrient media provides nutrients necessary

Lab 1 : Scientific Method 20 Table 2: Water quality vs. fish population 1. Based on the information in Table 2‚ (in the lab manual) what patterns do you observe? 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What are the independent and dependent variables? 5. What would be your control? 6. What type of graph would

Lab 1: Determining the pK a of PNP PNP or paranitrophenol is an organic compound that undergoes changes when the pH is manipulated of the solution. PNP is also an acid/ base indicator. The compounded starts off as internal conjugated ring with the hydroxyl group and the nitro group single bonded to the aromatic ring. This occurs at the pH of 5. At this point the aromatic compound is colorless and is in the ultraviolet range. However‚ as the pH begins to increase the hydroxyl group deprotonates

Purpose: We are doing this experiment to find the best ratio of potassium nitrate to powdered sugar for a model rocket motor that will create the most thrust. We are also testing if adding fins will affect the flight distance of the rocket. Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson‚ who has experimented with the best ratio of powdered sugar to potassium nitrate‚ has stated that “The 1 to 3 ratio is best for creating the most amount of thrust

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Maintaining Focus in Despair Class: GS2745 Date: 09/23/13 Unit#: 1 Lab#:1 I can recall a time where I had to maintain focus and persistence in spite of obstacles that I was facing at the time. This is in fact‚ in recent history as I was going through a combination of events that seems to have come out of nowhere. I am a full time student‚ and set to graduate in two quarters. Around the end of Spring quarter and beginning of the Summer Quarter‚ I lost my job. In addition to that‚ I was

RESULTS Aphid survival experiment Aphid survival rate varied with both of different combinations of predators-aphids and various times in presence or absence of ants (Table 2). GLM results showed that the interaction of ‘time × different combinations of predators and aphids × ant’ (F = 0.211; df = 10‚ 317; P = 0.995)‚ ‘ant × time’ (F = 0.490; df = 2‚ 317; P = 0.613) and ‘different combinations of predators and aphids × time’ (F = 1.639; df = 10‚ 317; P = 0.095) on the survival rate were not significant
