Considered to be most sensible life form, humans are able to experience everything happening around, be it witnessing the beauty of the nature or the trails of destruction of t...

-Esssentiality of Chemical Reactions  Chemical Reactions has the utmost importance in our life. Through these reactions we respire, plant grow, produce fruit, matter decomposes, human beings reproduce, grow, heal and think. Elements are the basic entity of matter in the universe. Each element is chemical and it chemically combines to form bonds like Oxygen combine to form O2 makes life feasible on earth. Chemical Reactions are at heart of every biological process in universe. From development of life on earth to the nuclear fusion in the distant stars. Even our ability to think, exploration of ideas are the result of Chemical Reactions.           IS THAT ALL? NO It gives power to our Gadgets through lithium Chemical Reaction. Bio and Electrochemical Reactions enable brain to store memories and promote thinking. To produce new antibodies for countering of drug resistant bacterias. Conversion of energy from one form to othe...

Decomposition Reactions play crucial role in our life. Numerous of these reactions are taking place in our surrrounding without our knowledge. In these reactions compounds are split into two or more than two constituents. These reactions are often undesirable but not always. Decomposition Reactions ranges from digestion to explosions. In digestion where starch decomposes into simpler sugars like like glucose whereas in explosions, chemical explosives that are compounds or substance generates lot of gas and heat upon the application of heat and pressure. Decomposition Reactions are also carried out by electricity that is used to extract several metals from their mineral ore. Well photography is just one of the amazing gifts of Science and Technology in which Silver halides are used in that are only silver with chlorine, bromine and iodine. 2AgCl ------> 2Ag + Cl2 2AgBr ------> 2Ag + Br2 2AgI    ------> 2Ag + I2 The light senstivity of these compounds ...

Arthropoda which is mostly insects are the largest phylum in Animal kingdom. Insects also have wide range of predators. Majority of them cannot even survive to their adolescent. Most of the deaths are caused by predation. In order to deal with this situation insects have developed wide variety of defense mechanism. Defense that withstood with them while they are hiding, escaping etc. Like in the female Ants, Bumblebees, Honey bees and Wasps have ovipositor, which is long thin hollow structure used to lay eggs. However, in some species, this tube has developed into a sting with a gland at its base. When insect is provoked it injects toxin into the victim. In insects like Bumblebees and Wasps has smooth sting with no barbs whereas Honeybees have barbed stings and this breaks off in the victim when it penetrates the skin of victim and this led to death of bee. Insects secreted toxins are venom(a poisonous substance). Ant secretes formic or methanoic acid. Honey bee veno...
