Cooking improves natural flavour and texture of food. For example roasting groundnuts, frying onions and papads, cooking rice and roasting coffee seeds improve the flavour.

The control of method in order to avoid loss of flavour substances.

The industrial society, when it was finally established in some pockets of the world, was found to be just the opposite of the agrarian society in very fundamental ways.

The marine ecosystem consists of seas, oceans and estuaries. Although it is very vast but it interacts with human life in various ways the oceans are used for navigation, fisheries, aquaculture, and acquisition of water, naval and military exercises. It is also used for discharge and dumping of variety of wastes.

There is no control on natural sources of radiation but earnest efforts can be made to decrease the level of pollution from anthropogenic sources. Preventive measures from radiation can be achieved by following the measures mentioned as follows:

Biofertilizer is the biologically active products or microbial inoculants of bacteria, algae and fungi, which may help biological nitrogen fixation for the benefit of plants.

A colourless, odourless, inflammable, toxic gas present in large quantities in the waste water from mined gases, especially in exhaust fumes from motor vehicles. This is the pollutant which is mostly produced by mankind, who generates more than 70% of its total volume. The toxic effect of carbon non oxide arises from the fact that it combines with the red blood cells pigment haemoglobin so as impedes the combination that normally occurs in the lungs of oxygen with haemoglobin.

High performance liquid chromatography (HPLC) has become a standard and routine method for separation and concentration of analyses. An HPLC system consists of a solvent reservoir, high pressure pumps, sample injection port, separation column, detector, and recorder units. HPLC is the result of attempts to increase the efficiency of liquid chromatography to the same level as that of gas chromatography.

Read the passage below and answer the questions that follow based on your understanding of the passage:

1. Which of the following statement about Fjord is incorrect?

The emissions of air pollutants depend upon the method of combustion and the type of fuel used. The combustion of all fuels results in exothermic oxidation of carbon, hydrogen, sulphur and nitrogen. In case of complete combustion, carbon dioxide, water vapour, nitrogen oxides, volatile and non-volatile trace metals such as Arsenic, Cadmium, Lead and Mercury would be the principal emission.

Biofertilizer is the biologically active products or microbial inoculants of bacteria, algae and fungi, which may help biological nitrogen fixation for the benefit of plants. Biofertilizers also include organic fertilizers (manures, etc.), which are rendered in an available form due to the interaction of micro­organisms or due to the interaction of micro-organisms or due to their association with plants.

Plastic waste management is a collective term for various approaches and strategies used to recycle plastic materials that would otherwise be dumped into landfills, or bodies of water, or otherwise contaminate the environment.

Every community undergoes a series of changes until a group in the area. This is called biotic succession. Succession is a sequence of changes in time of the species which inhabit an area from an initial pioneer community to a final climax community. In other word, the development of community by the action of vegetation on the environment leading to the development of new species is called succession.

Once there lived a lion in Gir Forest. He lay asleep one day. A little mouse came out of its hole and jumped on the body of the mighty lion. The lion opened his eyes and caught the mouse in his paw.

It was winter. It was practically raining every day. It snowed sometimes. A cricket lay starving in his home. He was hungry and could not get anything to eat. So he came out and went in search of some food to satisfy his hunger.
