burning use oxidation to release energy. In respiration‚ oxygen combines with glucose to release energy which can be used in the body. Also some heat is produced to keep the body warm. Burning normally occurs in oxygen (in form of O2) to form oxide. However‚ burning can take place in other gases such as chlorine. Also both of these reactions are exothermic - both reactions release heat after reacting with oxygen. Another similarity is that both reactions release energy after oxidation. For respiration

composed of many different types of cells. Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. The free radicals can start chain reaction in the body and cause damage to cells and important chemicals in the body. Free radicals are very unstable

Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Oxygen – is a clear‚ colorless‚ odorless‚ and tasteless gas that dissolves in water. Small but important amounts of it are dissolved in water. OXYGEN: Aquatic Life Depends on it Plants and Animals depend on dissolved oxygen for survival. Lack of dissolved oxygen can cause aquatic

WASTE IN DOWNDRAFT GASIFIER” In the article Partik.N.Sheth and B.V Babu performed studies on gas generation from wood waste in downdraft gasifier. They arranged an experimental setup of downdraft gasifier consisting of four zones drying‚ pyrolysis‚ oxidation and reduction. In downdraft gasifiers pyrolysed gas and moisture generated in drying and pyrolysis zones flow downwards. They fed the biomass in gasifier and oxidized it in the zone where continuous air was supplied from the two inlet air nozzles

The lake was surrounded by all kinds of trees: sugar maple tree‚ camphor tree‚etc. At the center of the lake‚ there were a few huge trunks lied down the peaceful lake. On the trunks‚ there were some ducks “quack” around as if they were planning to have a sunbath party. Around those the ducks‚ there were a few birds hovering

After cutting off his ear‚ he painted this picture‚ depicting an open window for fresh air and bandage probably soaked in camphor‚ to communicate that he is able to care for himself and does not need to be taken to an asylum. He used his art to convey his inner thoughts and emotions and as a post-impressionist‚ he made sure to capture all of his memories and emotions in each

Functions and structure of plant terpenes Terpenes are an enormous class of organic compounds‚ that are produced by a wide variety of plants and fungi‚ especially conifers. Terpenes are also produced by some of the living organisms‚ like swallowtail butterflies. They emit terpenes from their osmeterium. Terpenes are important materials for a plant as components of its body and as a material to protect it from external enemies since it has a strong smell and colorless. Terpenes are found in biological
