Ozone molecule has one single bond and one double bond.

The molar mass of H2O can be calculated as the following.

M(H2O)= [2 x M(H)] + [M(O)].

And we know that M(H) = 1g/mol, M(O) = 16g/mol.

So, M(H2O)= 2x1 + 16 = 18g/mol,

That means 1 mole of H2O contains 18g.

Hence, one mole of H2O corresponds to 18 grams.

The C.M of Kerala, Pinarayi Vijayan has recently launched e-health program “Jeevan Rekha” to make electronic health records of a population in Thiruvananthapuram.

It is a first-of-its-kind initiative in India to provide a centralised database of healthcare information and efficient service delivery to the people.

The new system would help in creating a good hospital management system and patient-friendly atmosphere in hospitals.

Once data of a patient is centralised, it would help the person get continuous treatment at all hospitals in the state.

A spreadsheet contains both rows and columns.

Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating β-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains. Golden rice was developed to help cope with vitamin A deficiency, a problem that prevails in developing countries, affecting millions (Underwood, 2000; UNICEF, 2000). Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.

The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of β-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice results in Pale Yellow color.
