    franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

    The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

    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

For example‚ a young adult in good health is expected to have the following FEV values:•FEV-0.5-50-60% of FVC•FEV-1-75-85% of FVC•FEV-2-95% of FVC•FEV-3-97% of FVCIn general‚ a normal result is 80-100% of the predicted value. Abnormal values are:•mild lung dysfunction-60-79%•moderate lung dysfunction-40-59%•Severe lung dysfunction-below 40% (SSO‚ 2). In the Schneider ’s Physical Test‚ the subject final test score number

    Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

    Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object
