Why carbon have strong attraction force.

Posted by Sanjeev Jha 6 years, 3 months ago

Gouri Patil 6 years, 3 months ago

It has strong attraction forces due to its ability of tetravalency. Tetravalency means it has 4 atoms in its outer shell so its valency is either +4 or -4 . Carbon never donate or gain electrons it always forms a covalent bond means it shares it electrons , and a new propert that is catenation it means that carbon van make chains of many carbon atoms but sulphur and silicon can make chains only upto 7 or 8 atoms.

Aadya Singh ? 6 years, 3 months ago

The heart is roughly triangular in shape. It is made of special muscle cardiac cell. The heart has four Chambers inside it. The upper two chambers are called Atrium and the lower two chambers are called ventricles. The two Atria receive blood from the 2 main veins. And the 2 ventricles transport blood to the entire body and lungs. The left Atrium is connected to the left ventricle through a valve V1 and the right Atrium is connected to the right ventricle to another valve V2. These valves prevent backflow of blood into Atria when the ventricle contract to pump blood out of heart to the rest of body. When the muscles of all the four Chambers of the heart are relaxed, the Pulmonary vein brings deoxygenated blood from the lungs into the left Atrium of the heart. When the left Atrium contracts, the oxygenated blood is pushed into the left ventricle through the valve V1. When the left ventricle contracts, the oxygenated blood is forced into the main artery called Aorta and then go into different body organs except the lungs. The main artery carry blood to all organ of the body. When the right Atrium contracts the ,deoxygenated blood is pushed into the right ventricle through the valve V2. And when the right ventricle contracts, deoxygenated blood is pumped into the lungs through the Pulmonary artery. In the lungs , deoxygenated blood releases its carbon dioxide and observes fresh oxygen from air. So, the blood becomes oxygenated again. This oxygenated blood is again sent to the left Atrium of heart why Pulmonary vein for circulation in the body.

Pepsin and trypsin

Yogita Ingle 6 years, 3 months ago

Enzymes are actually made up of 1000s of amino acids that are linked in a specific way to form different enzymes. The enzyme chains fold over to form unique shapes and it is these shapes that provide the enzyme with its characteristic chemical potential. Most enzymes also contain a non-protein component known as the co-factor.

The biochemical reactions occurring in the body are basically of 6 types and the enzymes that bring about these reactions are named accordingly:

Oxidoreductases: These enzymes bring about oxidation and reduction reactions and hence are called oxidoreductases. In these reactions, electrons in the form of hydride ions or hydrogen atoms are transferred. When a substrate is being oxidized, these enzymes act as the hydrogen donor. These enzymes are called dehydrogenases or reductases. When the oxygen atom is the acceptor, these enzymes are called oxidases.
Transferases: These enzymes are responsible for transferring functional groups from one molecule to another. Example: alanine aminotransferase which shuffles the alpha‐amino group between alanine and aspartate etc. Some transferases also transfer phosphate groups between ATP and other compounds, sugar residues to form disaccharides such as hexokinase in glycolysis.
Hydrolases: These enzymes catalyze reactions that involve the process of hydrolysis.They break single bonds by adding water. Some hydrolases function as digestive enzymes because they break the peptide bonds in proteins. Hydrolases can also be a type of transferases as they transfer the water molecule from one compound to another. Example: Glucose-6-phosphatase that removes the phosphate group from glucose-6-phosphate, leaving glucose and H3PO4.
Lyases: These enzymes catalyze reactions where functional groups are added to break double bonds in molecules or where double bonds are formed by the removal of functional groups. Example: Pyruvate decarboxylase is a lyase that removes CO2 from pyruvate. Other examples include deaminases and dehydratases.
Isomerases: These enzymes catalyze the reactions where a functional group is moved to another position within the same molecule such that the resulting molecule is actually an isomer of the earlier molecule. Example: triosephosphate isomerase and phosphoglucose isomerase for converting glucose 6-phosphate to fructose 6-phosphate.
Ligases: These enzymes perform a function that is opposite to that of the hydrolases. Where hydrolases break bonds by adding water, ligases form bonds by removal of the water component. There are different subclasses of ligases which involve the synthesis of ATP.

Yogita Ingle 6 years, 3 months ago

A bar magnet is a rectangular piece of an object, made up of iron, steel or any other ferromagnetic substance or ferromagnetic composite, that shows permanent magnetic properties. It has two poles, a north and a south pole such that when suspended freely, the magnet aligns itself so that the northern pole points towards the magnetic north pole of the earth.

Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
Directive Property – A freely suspended magnet always points in a north-south direction.

Yogita Ingle 6 years, 3 months ago

Genes are the parts of chromosome that control a particular character inherited by the offspring.

They are the segments of DNA that control a particular or more than one character.

Genes provide the necessary information for the formation of proteins. These proteins formed influence the size, shape, colours etc of the progeny.

So, overall they control the characteristics inherited.

What is the difference between dispersion of light and spectrum of light?

Posted by Rohit Raj Singh Maurya 6 years, 3 months ago

CBSE > Class 10 > Science

2 answers

Yogita Ingle 6 years, 3 months ago

<div>Dispersion:</div> <div>The phenomenon of splitting up of a white light into its constituent colours is called as dispersion. White light contains many wavelengths ( it contains lights of many wavelengths(colours)).Since their wavelengths are different, their speeds are different in a medium, but in vacuum all the wavelengths travel with the same speed. In a material medium, the speed of different wavelengths are diferent. So when a beam of white light passes through a medium, the material medium splits the white light into different components. This phenomenon is called dispersion. </div> <div>When white light passes through a prism, it spreads out into a band of seven colours,VIBGYOR. This band of colours obtained is called spectrum.Dispersion of light results in the formation of a spectrum.</div> <div> </div> <div>Scattering of light:</div> <div>Scattering of light is the deviation of light rays from its straight path. As light propagates through the atmosphere, it travels in a straight path until it is obstructed by bits of dust or gas molecules in the atmosphere. The process in which light gets deflected by the particles in the medium through which the light pases is called scattering. Here it is not the splitting of light on the other hand here the incident beam of light just get redirected after being striked by the atmospheric particles. The blue colour of the sky is due to the scattering of sunlight by the molecules of air . During sunrise and sunset sunlight has to travel greater distance , so shorter wavelengh gets scattered off and removed and only red wavelengths reach us.</div>

Spectrum- the components of seven colours of white light is, spectrum of light. Dispersion-a dividing of white light into its components of seven colours is , dispersion of light
