Bacteria

Cyanobactria, Earths atmosphear was with out Oxigen in between Two - Three million years this bacteria make Oxigan with the help of photosynthasis. Blue green pigment help to synthasis oxigen. Population of bacteria and Incressed and all life of other dead cause of over oxigen consentration. The Oxigen concentration incress in the atmosphear is also called as the time of Oxigen bombing time. methain was a green house gass but the Overoxigen cause production of carbon dioxide. The methain react with the Oxigen to form Carbon di oxide, Afer some millanium Oxigen leavel reach the twenty one persentage and more complex form of Life. Endosymbiosis occuared and internal Photosynthasis. This type of cell became plants. 728

Caffeine and Humen body

Caffeine is a adinosin Incressing chemical. No glycongen is stored in the Body and become more active. Brain signaling will be less if we do not use caffeine. It can also boost Dopamin in the cell. Adinosin resepters are Innumarable so there will be no effect to the caffeine in the body so we need to have more caffeine. Six thousand years ago the Tea was cultivated in china. 379

Electronegativity

The power of an atom in a molicule to attract electrons to itself. Linaus Pauling "The nature of Chemical Bond". A non polar covalent bond and polar covalant bond are diffrent vause of polar co valant bond do have partial negative charge. The tendancy of an electron to be free from bonds. 291

Atom

Atom is undevidable and it can view only on Electron microscope. Helium is One angstrom.Probability distribution can be found in the case of atom. Do have Neutron , Proton and Electron. 188

Cellular Respiration

ATP is formed by the combination of ADP and a Phosphate group. ATPase relese energy in the reaction with Phosphate group. Cellular respiration is the formation of energy from the Glucose.With one mole of glucose and Three mole of Oxigen we can produce six mole of carbon and six mole of water and energy.
