------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

the flies under the ideal conditions. After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to be 0.32 which most likely fall between the two values of 0.148 and 0.455. These two values correspond to a probability values of 0.70 and 0.50‚ and these two values lay to the left of the p- value of 0.05‚ which means the null hypothesis presented

melanogaster: Monohybrid Cross & Sex-Linked Inheritance October 6‚ 2012 Abstract This lab involved a monohybrid reciprocal cross and a sex-linked cross utilizing Drosophila melanogaster fruit flies. After sexing the flies‚ placing them in media‚ and letting them cross breed‚ we analyzed and recorded the phenotypes that were observed. The P1 flies were anesthetized then sexed by observing their phenotypes and equally distributed into the media we made for their copulation

research is using this information to reduce the amount of anoxia related stress humans with pulmonary diseases experience. Methods Each condition was tested with a separate single group of D. melanogaster (cold bath - 8 flies and warm bath – 11 flies)‚ and all of the flies used were approximately 1-9 day old males. Each group of D. melanogaster was held in a container that provided adequate nutrients prior to the experiment‚ and then transferred to a drowning container that held no nutrients.

Drosophila melanogaster: Mutant Fruit Flies Jessica E. Phillips Genetics 3301 April 13‚ 2012 Introduction: Drosophila melanogaster better known as the fruit fly can be found near rotting fruits‚ vegetables‚ or anywhere where there is food that has rotted and or fermented. (Potter‚ 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days

Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

In freshman year‚ I was placed in the honors Biology course. I had a lot of difficulty the first semester and never really attempted to study much. I didn’t want the second semester to be the same as the first semester‚ so I tried a lot harder by studying for every test and doing every assignment that was given. In the end of the semester‚ I earned an A with all of my hard work. In order for students to take an AP class at our school‚ we must apply to the class with an application. Acceptance is
