Enid Mary Blyton was the English children's writer published 59 new books in 1955.

Bilater monopoly occurs in a market where a single seller i.e, a only one monopoly and a single buyer i.e, one monopsony exists.

Polarity :: 

The polarity of a molecule defines its other physical properties such as melting point, boiling point, surface tension, vapor pressure etc... Simply, polarity occurs when the electron distribution in a molecule is asymmetric. This results in a net dipole moment in the molecule. One end of the molecule is charged negative while the other gets a positive charge.

The polarization of a molecule greatly depends on the shape of the molecule. A diatomic molecule like HF mentioned above has no issue of shape. The net dipole moment is only due to the uneven distribution of electrons between the two atoms. However, when there are more than two atoms involved in making a bond, there are many complexities.

The water molecule is of bent shape. Therefore, when the two pair of electrons shared by oxygen with two hydrogen atoms is pulled towards oxygen, the net dipole moment results in the direction of the oxygen atom. There is no other force to cancel out the resultant dipole moment. Hence, the water molecule is highly polar.

Ammonia molecule is of a pyramid shape and the electronegative N atom pulls the electrons towards itself. The three N-H bonds are not in the same plane; hence the dipole moments created do not get canceled out. This makes ammonia a polar molecule.

However, the dipole moments sometimes get canceled due to the shape of the molecules, making the molecule non-polar. Carbon dioxide is such a molecule.

Ribosomes comprise a complex macro molecular machine, found within all living cells, that serves as the site of biological protein synthesis. Ribosomes link amino acids together in the order specified by messenger RNA molecules.

TON is the word which is the unit of weight. In forward it has weight of 1000 kgs and in backwords NOT which has no weight.

An atom that loses or gains electrons is called as ion. Gaining of electron is negative charge and is called as Anion and lossing of eectron is called Cation.

The Ministry of Women and Child Development has launched #Childline1098 childline contest to spread awareness on human trafficking. 

Human trafficking is the trade of humans for the purpose of forced labour, sexual slavery, or commercial sexual exploitation for the trafficker or others.

The WCD Ministry has invited people to share images of the logo of Childline 1098, the nationwide emergency helpline for children in distress, that they spot at unique locations and send it with a tagline to win a cash price, in a bid to spread awareness on trafficking.

The contest has been organised to mark 'World Day against Trafficking in Persons' on July 30.

The Childline has been operating at 450 locations, including 76 key railway stations, across the country.

Complimentary angles are those two angles whose sum is 90 whereas two angles whose sum is 180 are called Supplementary angles.
