Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source.

Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal). Geothermal power plants require high-temperature (300°F to 700°F) hydrothermal resources that come from either dry steam wells or from hot water wells.

A:B = 200 : 169
A:C = 200 : 182
 CB = CA×AB 

182200×200169

=> 182:169

When C covers 182 m , B Covers 169 m
When C covers 350 m , B Covers 169182×350
=> 325 m

So C beats B by (350 - 325) = 25 m.

Uttar Pradesh is the most polluted state in India, with 15 of its cities among 30 cities with highest levels of toxic air in the country. Prime Minister Narendra Modi’s constituency Varanasi turned out to be the worst polluted city of UP. Countrywide, it came sixth.

Other towns and cities in UP on the list are Hapur, Bareilly, Firozabad, Kanpur, Agra, NOIDA, Allahabad, and Mathura where PM10 levels were way above permissible limits.

Kerala is the least polluted state in the country, India. In all the 14 districts of the state, NAAQ(National Ambient Air Quality Standards) standards are complied with and had lower concentrations of PM10. However, all the cities surpassed the PM10 standards prescribed by WHO.

The report - Airpocalypse II - is based on air pollution related data collected from Central and State Pollution Control Boards and Committees.

India was one of the main centres of world trade and industry. Peter the Great of Russia was led to exclaim: “Bear in mind that the commerce of India is the commerce of the world and ... he who can exclusively command it is the dictator of Europe.”

By trial and error method,

P=0, Q=9, R=0 satisfies the values.

Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation.

Mutations are changes in the DNA. A single mutation can have a large effect.

1) mutation - an alteration in DNA sequence, various types

2) intragenic recombination - results in entirely new associations of genes not present in either parental genome.

Two forms of intragenic recombination:

a) crossing over
b) independent assortment
3) reticulation – acquisition of genetic material from unrelated or relatively unrelated sources (e.g., hybrid species, horizontal gene transfer).
