Halobacterium Lab Investigation Mason Pirio 12/12/13 Period 5 Table Group 3 PS 2- Experiment Design PS 3- Conclusion Writing PS 13- Nitrogen Cycle Abstract- In this experiment we tested to see how well halobacterium grows in different levels of salinity. We found out that the higher salinity in the growth medium the better the halobacterium grows. Background Information- Halobacterium is a bacteria that is found in the great salt lake. Halobacterium is an extremeophile which means it thrives

Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

Alexis Sorensen Kant Final James Griffith 1:30-3:00(T/TH) 11/17/12 Pure Mathematics Immanuel Kant‚ a Prussian philosopher during the 1700s‚ examined the basis of human knowledge and its existence. Through rationalism and empiricism‚ Kant developed an individual model that supported the concept of pure mathematics. Kant’s logic allowed him to prove concepts that appeared unable to be proven. Pure mathematics‚ as an a priori cognition‚ can be considered to be an example of a concept that may

Kimmi Dodia- Biomedical Science- 1019971 Lab partner- Kim Harcourt Lab report- Experiment 1: Microbial Genetics Abstract The objective of this experiment was to introduce the study of bacterial genetics in order to identify the potency of different mutagenic agents. Our primary aim was to demonstrate the different techniques needed to isolate biosynthetic auxotrophic mutants using chemical‚ physical and transposon mutagenesis. The second aim was to plan and execute an experiment designed

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

The Effect of Metal Ions on Lichens Casey Stinnett ESC 1510 October 30‚ 2014 Introduction Lichens are a sybiotic association of fungus (mycobiont) and algae (Pediastrum boryanum . The fungus engulfs the algae‚ then supplies carbs‚ nitrogen‚ and vitamins while the algae photosynthesizes. This unusual relationship enables the lichen to grow in environments where neither fungus nor algae would normally be able to solely survive. They are found on every continent‚ ranging all the way from
