foundations of material science

Metallic surfaces exposed to acid rain are readily corroded. Textile fabrics, paper and leather products lose their material strength or disintegrate by the acid rain. Building materials such as limestone, marble, dolomite, mortar and slate are weakened on reaction with acid ra..

Materials to be transported include digested food, respiratory gases, hormones, excretory products, etc. The digested food includes sugars like glucose, amino acids, fatty acids and their derivatives. Blood which is the vascular tissue in man is over 90% water. Thus, only the water-solub..

Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substan..

Inorganic material derived from parent (material) rocks Organic material derived from dead and decayed materials Biological system - such as bacteria, fungi, algae, protozoa and other soil animals such as nematodes, earthworms etc. The air and wate..

Materials such as paper, some kinds of plastics and glass can are being recycled. Collect plastic, paper, glass and metal items and give them to people who recycle these materials. This decreases the volume of refuse and helps in the conservation of natural resources. A recove..

Question: Which are the materials transported in plants? Answer: The materials transported across the plant body are water, minerals, food and metabolites like the hormones and vitamin..

The exchange of materials between the cells and the blood is done directly. There are few blood vessels but they are not extensiv..

Circulatory System - The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particularly the more advanced forms, have a higher metabolic rate...
