Alcohol, ketone, alkene functional groups are present in 
cortisone.

Nitrogen bonds with carbon and hydrogen molecules and shows 
sp2 hybridisation.

The nitrogen is bonded to three CH3 groups and has a lone 
pair, so the hybridisation is sp3

enantiomeric excess= Aobs/Amax x 100
So ee is 50 %.so it is mix of 75 % of S and 25
% of

Three geometrical 1-bromo-1-methylcyclopentane(A),1-bromo-2-
methylcyclopentane(B) and 1-bromo-3-methylcyclopentane (c)
A is having only one isomer,B have 2 stereo isomersand C 
have 2 stereo isomer so total five isomers

Two positional isomer A and B & two Stereoisomer of each
so,total 4 isomers

In agricultural economics, system of cultivation using 
large amounts of labour and capital relative to land area. 
Large amounts of labour and capital are necessary to the 
application of fertilizer, insecticides, fungicides, and 
herbicides to growing crops, and capital is particularly 
important to the acquisition and maintenance of high-
efficiency machinery for planting. Intensive agriculture is 
an agricultural production system characterized by the 
significant use of inputs, and seeking to maximize the 
production. It is sometimes also called productivist 
agriculture. It relies on the use of chemical fertilizers, 
herbicides, fungicides, insecticides, plant growth 
regulators, pesticides. It is associated with the 
increasing use of modern practices and agricultural 
mechanization. An example of intensive farming can be seen 
in places such as the Philippines, on rice farms.Intensive 
agriculture made it possible to greatly increase 
productivity during the twentieth century, and helped 
ensure a proper and stable food supply for the growing 
population while at the same time decreasing the amount of 
land needed. Agricultural productivity gains allowed for 
the reduction in the farming population, mostly in 
developed countries. Increased per-acre productivity has 
allowed millions of acres of land in the United States that 
was once farmed to return to a natural state. 
Intensification of agriculture from the sixties to the 
eighties is also known as the green revolution. Developing 
nations often could not profit from the advantages of 
modern agriculture particularly because of poor climate and 
lack of funds.

One chromosome of a pair is called homologue.In Homologous 
pair two identical chromosomes are present. Each one 
chromosome in a Homologous pair is called Homologue.

Accession number (bioinformatics), a unique identifier 
given to a biological polymer sequence (DNA, protein) when 
it is submitted to a sequence database.
