microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

choose. The study recruited HPS121 students to participate in a limited and extensive choice experiment in context to hotels. There were 661 participants‚ each chose one hotel and where then surveyed using six questions; three demographic and three in regards to difficulty‚ motivation and satisfaction using a 7-point Likert scale. The findings supported the hypothesis and were consistent with past research. Satisfaction and difficulty of choice showed a statistically significant difference with limited

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

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

treat a patient correctly. The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown. Materials and Methods A test tube with an unknown microorganism will be retrieved. Once the test tube is retrieved‚ a steak for isolation will be completed in order to produce isolated colonies of the organism on an agar plate. The unknown test tube with the bacteria is flame sterilized using a Bunsen burner. Once the bacterium test tube

et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

6. FIRST DERIVATIVE ZERO CROSSING METHOD 6.1. ABSTRACT: Simple‚ specific‚ accurate and precise 1st order derivative zero-crossing spectroscopic method was developed for simultaneous determination of PHENYLEPHRINE and EBASTINE from their binary mixture. In this 1st derivative zero-crossing spectroscopic method the amplitudes of the 1st order derivative of the spectra of the binary mixture containing PHE and EBS were measured at 252.2 nm (zero crossing of EBS) for determination of PHE and at 274.8
