Greenhouse gas Greenhouse effect schematic showing energy flows between space‚ the atmosphere‚ and Earth’s surface. Energy exchanges are expressed in watts per square meter (W/m2). A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth’s atmosphere are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚

Amylopectin The absorbance value(x) read from cuvette containing starch and water represents the total amount of starch-iodine complex. The absorbance value(y) read from cuvette containing starch‚ water and α-amylase at the respective temperature or pH represents the amount of starch-iodine complex which is left after the enzyme has hydrolyzed the starch.In order to get the amount of product;P (maltose and glucose) formed‚ need to subtract the (y) value from the (x) value.

Introduction The following critical interpretation of popular culture is based on the song called “Where is the Love” by the band Black Eyed Peas which was written in 2003. An interpretation of the message that the author is trying to convey in the song is the idea that there is massive discrimination and hatred amongst people in the United States. Furthermore‚ the song suggests that US citizens are ignorant of the world around them and that love‚ which can be viewed as human kindness and civility

Effect of Different Microwave Doses on Vicia faba Germination‚ Growth and Genetic makeup Problem: Some areas are affected by high frequencies of microwaves; this affects plant growth‚ germination and genetic makeup‚ which leads to a loss in crop yield‚ including one of the major crops of high economic importance‚ the Vicia faba. Abstract: Plants and their stresses have been of very great importance lately. Since there are many kinds of stresses‚ we only studied one‚ but a very important

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of colors depending on its pH level was

Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic.
