Plants grow from the seeds, and the seeds are covered by a natural coating known as seed coat. Water is very helpful to develop a seedling from the embryo of a seed and further helps the seedling to break the seed coat. This process is known as germination. Some seeds have very hard seed coat, [...]

Most of the people rely only on weighing scale to know if they are overweight. But body mass index (BMI) is better way to know about your total body fat according to your weight and height. By calculating body mass index you can easily conclude or get the idea that how much weight you have [...]

Exterior coating of Statue of Liberty is made up of copper metal which protects the statue. Copper can easily react with other elements. The Statue of Liberty is green in color because a process called oxidation has happened.
In this process copper reacts with oxygen in the air and forms a pinkish oxide compound or we [...]

Learning about the body language is a skill. If we can interpret the body language of others then we can better understand what he feels and thinks, whether his words are matching with his words or not. To interpret body language you have to observe a person from top to bottom. So let us take [...]

You must have heard the term body fat percentage. It is the percentage of fat present in your body. If your body weighs 160 pounds and you have 10 percent of fat then your body contains 16 pounds of fat tissues and 144 pounds of lean tissue or fat free tissue like bone, muscle, organ [...]

Plastics bags are made up of polyethylene in its low density form (LDPE). This polythene is derived from natural gas, crude oil and non-renewable sources.
Blown film extrusion or “tubular film extrusion” is one of the most common ways to make a plastic bag. The plastic resin pellets of different types are taken from storage bin [...]

Grass has green color because it has a pigment like other plants called as chlorophyll. This pigment is found in organelles (little factories) in a plant cell known as chloroplasts which is involved in the process called photosynthesis (a process by which plants make their food). In this process carbon dioxide and water make glucose [...]

Plastics are used in many products. It provides protective surface for countertops and cabinets also. Plastic surfaces can be easily cleaned. Things required to clean plastics are:-
Kitchen cleaner spray
Mild detergent
Warm water
Sponge
Nylon bristled brush
Mild glass cleaner
Soft cloths
Plastics do not absorb stains so it has to be wiped off. First of all mix the detergent with water [...]

Plastics can be joined or welded together in many ways. One is with electrical welding leister. Generally the plastics products used in cars, bikes and other vehicles are thermoplastics so they can be easily molded or welded. Some manufacturer marks code for material identification like ABS, PP. Leister 100.726 can easily weld the cracks, working [...]

Plastics are used in wide range of things. So it is produced in a very huge amount and its convenience is undeniable. Recycling of plastic is very important because it is made from the oil which will cause the regular depletion of this limited resource. With the recycling of plastic we can save oil and [...]

Polymers are primarily made up of carbon, hydrogen and oxygen. They are the long chains which repeat themselves again and again.
Many steps are evolved in the production of plastics
Polymerization
Most common raw material required for the manufacture of plastics is oil and natural gas but they are also processed from corn and other biomass. First of [...]

Plastics are a type of polymer or synthetic which is much like resins found in plants and trees. Polymers are made up of carbon string and other substances. The units in every string are called monomers. These monomers when goes through chain linking reaction then carbons join with each other forming polymer. According to dictionary [...]

Global warming is the trapping of heat on the earth surface due to the rise in temperature caused by transportation, burning of fossil feul, emission of gases from the factories etc. It affects in many ways to all the living beings on the earth.
Natural disaster
Global warming can cause more serious, frequent and strong storms, tornadoes, [...]

Global warming is the increase in temperature of earth due to greenhouse gases like carbon dioxide CO2 which causes nine to 26 percent of greenhouse effect, water vapors has 36 to 70 percent and methane CH4 has four to nine percent. These gases are useful up to a limit to make planet habitable but excess [...]

The main causes of global warming are greenhouse gases which are released into the atmosphere through various human activities. We can take many steps to reduce global warming.
On roads
Carbon dioxide is released into the air by the burning of fuels which contribute in the climate change. This can be reduced by improving fuel efficiency of [...]

Global warming is one of the burning issues nowadays. It is the natural warming of the atmosphere (as well as natural cooling). These days global warming refers to the gradually increasing temperature of the earth due to the greenhouse gases like carbon dioxide, methane and nitrogen that are accumulating in the earth’s atmosphere and increasing [...]

The word vitamin is made from the words “vitamine” which means “vital amine”. These are the organic compounds found in a small amount in the food and perform a particular function in cells and tissues. Vitamins react with enzymes and produce the energy from the food and also help in many chemical activities of the [...]

Protein performs many functions in our body. Our body is 45 percent of proteins. It is a very important substance for our bodies which help in growth, repair and protection. Functions of proteins are very much dependent on the molecular structure.
It performs many functions in the body
1) It acts as the enzymes which are catalysts [...]

Protein is a group of complex organic molecules which consist of carbon, oxygen, hydrogen, nitrogen, sulfur and also have the one or number of amino acids chain. The word synthesis means that when smaller molecules come together to form a larger molecules. Similarly protein synthesis is a process in which small amino acids molecules put [...]

Protein word is taken from a Greek word “prota” which means “primary importance”. Jons Jakob Berzelius, a Swedish scientist gave it a name in 1838 but the important role of protein was fully appreciated after 1926.
Proteins are the primary substance of living organisms as it provides the molecular machinery to the cells of living organisms. [...]
