OXYGEN-CARBON CYCLE The carbon-oxygen cycles are actually two independent cycles. However‚ both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis‚ plants take in carbon dioxide (CO2) and absorb water (H2O) with the help

surface areas of 300 - 2‚000 square meters per gram. Charcoals are widely used to adsorb odorous or colored substances from gases or liquids." The problem with charcoals is that its production efficiencies are generally low‚ with as much as 60-80% of energy in the wood lost. Adding to this loss is the poor efficiency of many charcoal stoves‚ some as low as 3%. (http://www.burndesignlab.org/why-stoves/the-problem-of-charcoal/) However‚ the benefits of this study is that we can help the environment

from Penicillium fungi. Penicillin is a historically significant drug being the first antibiotic discovered. Penicillin is a Betalactam antibiotic and is used in the treatment of bacterial infections caused by susceptible‚ usually Gram-positive‚ organisms. Figure1: Core structure of Penicillin: R-C9H11N2O4S History: In September 1928‚ Alexander Fleming accidentally discovered penicillin when he was engaged in studying different kinds of bacteria and molds in his laboratory. He once opened one of

reactive pigment that can absorb the energy from the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started engaging in their photosynthetic reactions‚ large amounts of oxygen were suddenly released in the atmosphere

nation’s schools. allowing college professors to possess guns on campus will only lead to more gun deaths and injuries‚ not less. Federal and state laws that prohibit guns at schools and pose harsh penalties for gun possession‚ in contrast‚ help keep our children and educators safe. College and Universities are generally safe havens from gun violence. Allowing guns

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the

this project is to study the rates of fermentation of the following fruit or vegetable juices. i. Apple juice ii. Carrot juice INTRODUCTION Fermentation is the slow decomposition of complex organic compound into simpler compounds by the action of enzymes. Enzymes are complex organic compounds‚ generally proteins. Examples of fermentation are: souring of milk or curd‚ bread making‚ wine making and brewing. The word Fermentation has been derived from Latin (Ferver which

The creation of these minimal genomes can be helpful and harmful at the same time. There are many opinions out there about the subject‚ I will share some of those and my position on the subject. First let me just start with my personal position on minimal

one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test done was a differential stain (gram stain) to determine the unknown microorganism cell shape and arrangement. The gram staining is done by first putting a sample of the unknown bacteria on a slide and it was heat fixed taking care not to over or under fixed the slide. The slide was flooded with crystal violet and let stand for 30 seconds
