By breaking down dead organic material, they continue the cycle of nutrients through ecosystems. In addition, most vascular&nbsp;<a href="">plants</a>&nbsp;could not grow without the symbiotic fungi, or&nbsp;mycorrhizae, that&nbsp; increase their roots and supply essential nutrients. Other fungi provide numerous drugs (such as penicillin and other antibiotics), foods like mushrooms, truffles and morels, and the bubbles in bread, champagne, and beer.</p> <p><strong><a href=""></a></strong></p> 2019-01-25T16:11:43+06:00 ##submission.copyrightStatement## Types and Classification of Microb- Fungi 2020-06-06T22:16:12+06:00 Sariani Salaami Muhamed <p>Fungior&nbsp; microbe&nbsp; take&nbsp; a&nbsp; single celled or very complex multicellular organisms. They are found in just about any habitat but&nbsp; many&nbsp; of&nbsp; them&nbsp;&nbsp; live on the land, mainly in soil or on plant material rather than in sea or fresh water. A group called the decomposers grow in the soil or on dead plant matter where they play an important role in the cycling of carbon and other elements. Some are parasites of plants causing diseases such as mildews, rusts, scabs or canker. In crops fungal diseases can lead to significant monetary loss for the farmer. A very&nbsp; a few&nbsp; number of fungi&nbsp; increase&nbsp; diseases in animals. In humans these include skin diseases such as athletes’ foot, ringworm and thrush.</p> <p><strong><a href=""></a></strong></p> 2019-01-25T16:16:22+06:00 ##submission.copyrightStatement## Principles of Nucleophilic Substitution 2020-06-06T22:16:11+06:00 Aliakbar Muhamdi Ameri <p>The work reported in this&nbsp; theoretical&nbsp; paper&nbsp; deals with types of&nbsp; substitution&nbsp; reaction ( sn1 , sn2 , conditions&nbsp; of&nbsp; both&nbsp; reactions , methods&nbsp; of&nbsp; both&nbsp; reactions , diagram&nbsp; of&nbsp; reactions , energy&nbsp; for&nbsp; reactions, types&nbsp; of&nbsp; reactants ,&nbsp; products, rate&nbsp; of&nbsp; reactions , steps&nbsp; of&nbsp; reactions, transition state&nbsp; for&nbsp; reaction)&nbsp; and&nbsp; other reactions.</p> <p><strong><a href=""></a></strong></p> 2019-01-25T16:21:20+06:00 ##submission.copyrightStatement## Agents and Cancer Development 2020-06-06T22:16:10+06:00 Hassan Akbari Rahimi <p>Population (epidemiological) and laboratory studies have led to the discovery of many potential environmental factors in the initiation, promotion and progression of cancer. Starting with Pott's observations in the 18th century, certain occupations have been associated with an increased risk of cancer development. The recognition of increased scrotal cancer in chimney sweeps due to coal and tar exposure was followed by an observation in a British factory that all men distilling 2-napthylamine developed bladder cancer<strong>.</strong></p> <p><strong><a href=""></a></strong></p> 2019-01-25T16:26:46+06:00 ##submission.copyrightStatement## Environmental Causes of Cancer 2020-06-06T22:16:10+06:00 Aliakbar Muhamdi Ameri <p>This&nbsp; work&nbsp;&nbsp; explained&nbsp;&nbsp; most&nbsp; causes&nbsp; of&nbsp; tumor&nbsp;&nbsp; , cancer&nbsp; in&nbsp; cells&nbsp; (&nbsp; environmental , radiation , chem-radiation , other&nbsp; like&nbsp; food&nbsp; ,&nbsp; pollution&nbsp; in air ,&nbsp;&nbsp; water&nbsp;&nbsp;&nbsp; and&nbsp; food ) .Cancer is the second-leading cause of death in the world.
