Biology serve mankind in very fields. As follows 1) In the Field of  Health               Biology serves mankind in the field of health as follows. a. It has helped the men in combating fatal diseases like malaria, smallpox, tuberculosis etc. b. It has provided a cure for some diseases like cancer through radiotherapy and chemotherapy. c. We have been able to bring epidemics under control. d. We have reduced infants mortality rates etc. e. The science of biology serves mankind in coming to our rescue by finding means to increase food production and by controlling the increase in human population. God gives knowledge to biologists,,, that's why they serve humanity 2) In the Field of Agriculture: a. Biology serves mankind in agriculture by hydroponics possible whereby plants can be grown in solution or moist material containing minerals, instead of growing in soil. b. Biology has provided biological control for certain pest of food crops. c. Recently biology has made possible the clo

Phyletic lineage: the simple meaning is the record of living things and plants from their roots to now time Total Number of Species: The total number of species are 1,500,000 of organisms, currently known to science. More than half of these are insects (53.1%) and other 17.6% (2,50,000) are vascular plants. Animals other than insect are 19.9% (281,000) species and 904% are fungi, algae, protozoa, and various other prokaryotes. This list is far from being complete. Various careful estimates place the entire range of species between five and thirty million. Out of there, only 1.5 million number of species have been identified so far. Evolution: According to scientists, life today has come to exist through phyletic lineages of the organisms living in past. This is only a theory and having none of the proofs. According to Religion God or ALLAH created the universe. When he wants this type of species should disappear from the earth. He Does. When He wants this species should create. So He c

To understand this article must read my article Carbohydrates. Oligosaccharides They are derivates of carbohydrates. There function is as follows. They also called disaccharides. They are less sweet in taste. They are less soluble in water. On chemical reaction oligosaccharides yield from 2 to 10 monosaccharides. And they further decompose. The covalent bond between two monosaccharides is called glucoside bond. Important disaccharides are maltose, sucrose and lactose. Polysaccharides: Polysaccharides are the most complex and most abundant carbohydrates in nature They are usually branched. They are tasteless. They are fashioned by many sugar units joined by glycosidic bonds. They have a high molecular weight. They are only sparingly soluble in water. Some important kinds are starch, glycogen, cellulose, dextrin, agar, pectin and chitin. Get True Knowledge

To understand this article must read my article Carbohydrates. Monosaccharides: The definition and function as described. Definition of monosaccharides is that these belong to a family of carbohydrates. And its performance is to supply energy to the body. These are simple sugars. They are very sweet in taste. They are easily soluble in water. They cannot be further hydrolysed into simpler sugars. Aldehydes and Ketones: Chemically the are either polyhydroxy aldehydes or ketones. All carbon atoms in monosaccharides except one have a hydroxyl group. The remaining atom is either a neighbourhood of associate degree cluster|aldehyde radical|group|radical|chemical group} or a keto group. Aldo Sugar: The sugar with aldehyde group is called aldo sugar. Keto Sugar: The sugar with the keto group is called keto sugar. Classification of Monosaccharides These are classified into the following types, depending upon the number of carbons in a molecule. Trioses: these contain three carbon molecules Tet

Carbohydrates The word carbohydrates literally mean hydrated carbon. They are composed of carbon, hydrogen and oxygen and the ratio of hydrogen and oxygen is the same as in water i.e 2:1 There general formula is C^n (H^2O)^n where 'n' is that the number from 3 to several thousand. Chemically, carbohydrates are defined (definition) as polyhydroxy aldehydes or ketones, or complex substance, which on the hydrolysis yield polyhydroxy aldehyde or ketone subunits. Sources of Carbohydrates The source of carbohydrates is green plants. These are the primary products of photosynthesis. Other compounds of plants are produced from carbohydrates by various chemical reactions. Classification of Carbohydrates Carbohydrates are called 'saccharides' derived from the Greek word 'sakcharon' meaning sugar. They are Classified into three groups 1. Monosaccharides 2. Oligosaccharides 3. Polysaccharides Get True Knowledge

There is the importance of water in living things. Water is the medium of life. It is the foremost overabundant compound all told living things. Its amount of living things varies from 65 to 89%. Human tissues contain about 20 per cent of water in bone cells and 85 per cent in brain cells. Water has these significant properties. it's the importance of water. 1. Solvent Property Due to its polarity, water is an excellent solvent for polar substances. Ionic substances when dissolving in water, dissociate into positive and negative ions. It's another importance of water. 2. Heat Capacity There is another importance of water that it had a great ability of absorption of heat. The specific heat capacity of water the number of calories required to raise the temperature of 1g of water from 15 to 16 C is 1 calorie. Because much energy to require to break down hydrogen bonds. 3. Heat of Vaporization Water absorbs a lot of heat because it changes from liquid to gas. The heat of vaporizati
