 Weeds are unwanted plants. They grow with crops. They compete for nutrients and water with main crop. So weeds are very harmful. Process of controlling the weed is called weeding. Weeding is done manually by using khurpi and by using mechanical machines. Weeds are also controlled by using some chemical substances like 2, 4-D. These chemicals are called weedicide and used to kill and destroy the weed.

Solution: The electrodepositing reaction takes place in an electrolytic solution. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material.

LPG is a liquid fuel , its calorific value is more, it does not produce any smock,

Yogita Ingle 4 years ago

Wood has been a traditional fuel for both domestic and industrial use. However, it produces a lot of smoke that can cause respiratory problems. Also, wood is obtained from trees. Thus, using wood as a fuel causes deforestation. Therefore, slowly wood is replaced by LPG, which is a liquefied form of petroleum gas. It does not give out smoke and other pollutants and is a cleaner fuel. Again, fuel efficiency of LPG is more than that of wood. The calorific value of LPG is 55000 kj/kg, while that of wood is between 17000 to 22000 kj/kg. Hence, LPG is favoured over wood.

There are three zones in flame, viz. outer zone, middle zone and inner zone.

Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.

Middle Zone: This zone is yellow and orange in colour. This zone is moderately hot because partial combustion takes place in this zone.

Inner Zone: This zone is dark in colour. This is the coolest part of the flame because no combustion takes place in this zone.

Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.

In Eukaryotic cells, genetic material is present in the nucleus in chromosomes, which is made up of highly organized DNA molecules with histone proteins supporting its structure.

Chromosome means ‘coloured body’, that refers to its staining ability by certain dyes.

Factors affecting speed of sound.V∝T​ Pressure has no effect on velocity of sound as long as there is no change in temperature. Vmedium​=φB​​ for liquid and gas.V=φV​​ for solidsNewton's formula : V=φP​​ From the above concepts, it is clear that speed of sound does not depend upon humidity. There is very insignificant change in sound velocity with the change in humidity of the medium.

 The digestion of fats in the intestine is aided by emulsification. Emulsification is the process of the breaking up of fat globules into much smaller emulsion droplets. This process is performed by the bile salts. Emulsification greatly increases the surface area where water-soluble lipase enzyme breaks lipids into fatty acids and monoglycerides. Bile salt combines with phospholipids in chyme and emulsified the hydrophobic end with lipid and hydrophilic end with water, and break down the insoluble lipid globule into the simple form by enzymatic activity.
