Golgi apparatus was discovered in the year 1898 by an Italian biologist Camillo Golgi. It was on of the first cellular organelles to be discovered and observed in detail due to its LARGE size. The term Golgi apparatus was used in 1910 and in 1913 it first appeared in the scientific literature. Golgi Apparatus StructureThe Golgi apparatus is a major organelle in most of the eukarytoic cells. They are MEMBRANE bound organelles, which are sac-like. They are found in the cytoplasm of plant and animal cells. The Golgi complex is composed of stacks of membrane-bound structures, these structures are known as the cisternae. An individual stack of the cisternae is sometimes referred as dictyosome. In a typical animal cell, there are about 40 to 100 stacks. In a stack there are about FOUR to eight cisternae. Each cisternae is a disc enclosed in a membrane, it possess special enzymes of the Golgi which help to modify and transport of the modified proteins to their destination. The flat sacs of the cisternae are stacked and is bent and semicircular in shape. Each group of stacks is membrane bound and its insides are separated from the cytoplasm of the cell.The interaction in the Golgi membrane in responsible for the unique shape of the apparatus. The Golgi complex is polar in nature. The membranes of one end of the stack is different in composition and thickness to the membranes at the other end. One end of the stack is known as the cis face, it is the 'receiving department" while the other end is the trans face and is the "shipping department". The cis face of the Golgi apparatus is closely associated with the endoplasmic reticulum. Golgi Apparatus FunctionThe cell synthesize a huge amount of variety of macromolecules. The main function of the Golgi apparatus is to modify, sort and package the macromolecules that are synthesized by the cells for secretion PURPOSES or for use within the cell. It mainly MODIFIES the proteins that are prepared by the rough endoplasmic reticulum. They are also involved in the transport of lipid molecules around the cell.They also create lysosomes. The Golgi complex is thus referred as post office where the molecules are packaged, labelled and sent to different parts of the cell. The enzymes in the cisternae have the ability to modify proteins by the addition of carbohydrates and phosphate by the process of glycosylation and phoshphorylation respectively.In order to modify the proteins the golgi complex imports substances like nucleotides from the cytosol of the cell. The modifications brought about by the golgi body might  form a signal sequence. This determines the final destination of the protein. The Golgi complex also plays an important role in the production of proteoglycans. The proteoglycans are molecules that are present in the extracellular matrix of the animal cells.It is also a major site of synthesis of carbohydrates. These carbohydratres includes the synthesis of glycoasaminoglycans, Golgi attaches to these polysaccharides which then attaches to a protein produced in the endeoplasmic reticulum to form proteoglycans. The Golgi involves in the sulfation process of certain molecules. The process of phosphorylation of molecules by the Golgi requires the import of ATP into the lumen of the Golgi.

Phenyl methyl ether (anisole)reacts with HI to give PHENOL and methyl iodide and not iodobenzene and methyl alcohol because the lone pair of O are involved in resonace (+ mesomeric effect) with the benzene ring and imparts it a double bond CHARACTER and increases the C-O bond strength with the benzene ring. Moreover, the reaction goes via SN 2 mechanism which prefers the attack of nucleophile I−  from LEAST hindered side of the molecule. Thus it prefers to attack the methyl group. Hence Phenyl methyl ether (anisole) reacts with HI to give phenol and methyl iodide and not iodobenzene and methyl alcohol because I−  ion prefers to combine with the smaller group in order to minimise steric hindrance.

C-C DOUBLE bondExplanation:ethylene ( ethene) is a COMPOUND formed DUE to the double bonding between the carbon atoms.thus, it has c to c double BOND.

Soil is made up of a lot of different STUFF, but you can break it down into TWO categories - organic material, and mineral material. ... This is the stuff that makes soil fertile - the nutrients that plants use. So, soil is far from a PURE substance, and can vary QUITE a bit in composition, depending on geography.

tion:Tearing of paper - Tearing of paper is a PHYSICAL change as it doesn't affect the chemical composition of the paper but it causes change in its SHAPE and size. And also, it is an irreversible change as we cannot get the big piece of paper BACK or join the pieces to MAKE it the original paper again.hope it will help you mark me as brilliant

In the solid-state, the individual particles of a SUBSTANCE are in fixed positions with respect to each other because there is not enough THERMAL energy to overcome the intermolecular INTERACTIONS between the particles. As a result, solids have a definite shape and volume and molecules are most tightly packed in solids.Most solids are HARD, but some (like waxes) are RELATIVELY soft .Many solids composed of ions can also be quite brittle.

Using the relation, ρ=  RT /PM Under the same CONDITIONS, ρ∝M ⇒  M1/ M2=  ρ1/ρ2Given,ρ2 =2*ρ1 MOLECULAR WEIGHT of Nitrogen=M1 ​                                            =28 g mol^−1M2=28*2ρ1/ρ1M2=56 g mol^-1

Expand PVC - expanded polyvinyl chloride It is a LIGHTWEIGHT, yet rigid, expanded foam polyvinyl chloride. PVC is a CHEMICALLY STABLE material that shows little change in molecular structureof mechanical strength. PVC's free deformation is considerably low compared to other plastics, due to its limited molecular motion at ordinary temparature, whereas PE and PP have grater molecular notion in their AMORPHOUS section. Due to its versatile properties, lightweight, durable, low cost and processability, PVC is now replacing traditional building materials like wood, metal, concrete, RUBBER, ceramics,etc. in several applications.

AMING OF CO-ORDIANTION COMPOUNDSIn IUPAC nomenclature, the basic rules are :-The name of ligend is mentioned before the name of central METAL ion.If the co-ordination sphere is negatively charged, the name of central metal ion ends with the suffix 'ate' . Sc - Scandate , Cr - Chromate , Co - Cobaltate The name of negatively charged li ends with 'ido' For EXAMPLE :- Chlorido, Bromido, Iodido The oxidation state of central metal ion is mention inside a bracket.For a similar ligend ATTACHED more than one time, we use the prefix :- Di, Tri , Tetra, Penta , HEXA .Ligend are arranged in alphabetical order of their names but the prefix like Di , Tri etc. are not considered.For BIDENTATE ligend ,we use bis . For example :- bis(ethane-1,2-diamine)* Ligend is not the correct spelling,it is due to some technical issuesSOLUTIONS :- Considering above rules, The IUPAC name of the complexes will be :- [Co(CN)6] ³- => Hexacyanocobalate(iii) ion [Cr(H20)6]³+ => HexaaquaChromium(iii) ion

It is a mixture of hydrocarbons (molecules that contain only carbon and hydrogen and gases (most notably methane, ETHANE, propane, and butane) that exist naturally in rocks beneath the surface of the earth. it is widely USED as a heating source, and in some cases specific portions of the natural gas are used as starting materials in industrial processes. natural gas is the product of the decaying of living matter over millions of years. specific CONDITIONS (including low OXYGEN levels) are necessary for this to occur. the hydrogen gases are trapped in GEOLOGICAL formations known as anticlines. each of the major hydrocarbon components of natural gas is used as a fuel source.before natural gas can be used as a fuel, it must undergo extensive processing to remove almost all materials other than methane. the by-products of that processing include ethane, propane, butanes, pentanes and higher molecular weight hydrocarbons, elemental sulfur, and sometimes helium and nitrogen.natural gas is a versatile source of energy, which can be used by different actors. heating and electricity generation have been the main traditional uses.hope this helps you............. pl
