PART B

11. Read the following passage carefully and answer the questions given at the end of it: (1*15=15)

The study of control processes in the electronic, mechanical, and biological systems is known as cybernetics. The word was coined in 1948 by the American mathematician Norbert Wiener from the Greek word meaning pilot or steersman. Cybernetics is concerned with the analysis of the flow of information in both living organisms and machines, but it is particularly concerned with systems that are capable of regulating their own operations without human control.

Automatic regulation is accomplished by using information about the state of the end products that is fed back to the regulating device, causing it to modify or correct production procedures if necessary. The concept of feedback is at the very heart of cybernetics’ and is what makes a system automatic and self –regulating. A simple example of a self-regulating machine is a thermostat, which reacts to continual feedback about the outside temperature and responds accordingly to achieve the temperature that has been programmed into it.

The application of cybernetics’ are wide reaching, appearing in science, engineering, technology, sociology, economics, education and medicine. Computers can keep a patient alive during a surgical operation a making instantaneous modifications based on a constant flow of information. In education, teaching machines use cybernetics principles to instruct students on an individual basis. In the home, automation is present in such everyday products as refrigerators, coffeemakers’, and dishwashers’. In industry, automation is increasing its applications, although it is currently appliedprimarily to the large-scale production of single units. In industries in which a break in the flow of production can ruin the product, automatic controls are invaluable. Chemical and petroleum plants are now almost completely automatic, as are industries involved in the production of chemicals and atomic energy. Automation has become the answer when human safety is the number one priority.

  1. Read the following passage carefully and answer the questions given at the end of it: (1x14=14)

Humans have struggled against weeds since the beginnings of agriculture. Marring our gardens is one of the milder effects of weeds- any plants that thrive where they are unwanted. The clog waterways, destroy wildlife habitats, and impede farming. Their spread eliminates grazing areas and accounts for one third of crop loss; they compete for sunlight, nutrients, and water with useful plants.

The global need for weed control has been answered mainly by the chemical industry. Its herbicides are effective and sometimes necessary, but some pose serious problems, particularly, if misused. Toxic compounds threaten animal and public health when they accumulate in food plants, ground water and drinking water. They also harm workers who apply them.

In recent years, the chemical industry has introduced several herbicides that are more ecologically sound. Yet new chemicals alone cannot solve the world’s weed problems. Hence scientists are exploring the innate weed killing powers organisms, primarily insects and microorganisms.

The biological agents now in use are environmentally benign and are harmless to humans. They can be chosen for their ability to attack selected targets and leave crops and other plants untouched. In contrast, some of the most effective chemicals kill virtually all the plants they come in contact with sparing only those that are naturally resistant or have been genetically modified for resistance. Furthermore, a number of biological agents can be administered only once, after which no added applications are needed. Chemicals typically must be used several times per growing season.

PART-B [30 Marks]

11. Read the following passage carefully and answer the questions given at the end of it:

Sun light is usually known as white light, which is a combination of all the colours. When sunlight shines on an object, some of the light is absorbed, whereas the remaining light is reflected by the object. This reflected light gives the colour for that object.

Most flowers in nature are varyingly and brightly coloured. The colour of a flower depends on the absorption and reflection of certaincolours by the petals of that flower. Most o f the plants parts including flower petals contain various pigments such as chlorophyll, carotene, anthocyanin, etc.

These pigments, depending on their concentration, absorb certain wavelengths of a white light, and reflect the other wavelengths, which in turn gives the colour to a plant part. The red rose petals contain anthocyanins, which reflect mostly the red colour with a little blue or violet colour, thus giving the red colour to the rose petals.

The white flowers may have the pigments or air spaces in the petals, which reflect the entire white light shining on them and thus giving the white colour. The black colour is just an opposite phenomenon to white colour. In this ease, the object has to absorb the entire white light shining on it and thus giving the black colour to that object.

The brightly coloured flower is an essential part for most plants, since they have to attract the pollinators. It is rare to have a black coloured flower in nature. Pollination is an important process in a plant’s lifecycle, since its reproduction depends on this process.

Insects such as bees, butterflies, moths, beetles and flies are well known pollinators. The brightly coloured flowers attract the insect pollinators, which ensure their eventual fruit and seed setting. Moths are active during the night time, and hence most of the night blooming flowers which are pollinated by moths produce white or pale coloured flowers. Thus the flower colours, although they are not the only factor in pollination process, have long co-evolutionary relationship with their insect pollinators, and hence most flowers are varyingly coloured, but not black.

(a)Choose the correct answer: (4x1=4)

(i) What is called white light?

1.moon light 2. Day light 3.Sunlight 4. Bright light

(ii) What gives colour to any object?

1.reflected sunlight 2. Refracted sunlight 3.deflected sunlight 4. Absorbed sunlight

(iii) Which of the following is not a pigment?

1.Chlorophyll 2. Chlorine 3.carotene 4.anthocyanin

(iv) Which of the following is not a pollinator?

1.bees 2.butterflies 3. Beetles 4.buffaloes

(b) Mention whether the following statements are True or False: (6x1=6)

(i)The flowers that reflect the entire white light become white flowers.

(ii) Anthocyanins add red colour to the red rose.

(iii)Moths hardly work during the night.

(iv)Flower colour is the only factor in pollination process.

(v)The colour of a flower has vital role in pollination.

(iv) Flowers are not usually black because insects are black.

12. (a)Write a letter placing an order for certain items of sports goods with Bharat Sports Good Company, 12, Anna Salai, Chennai-2. (1x10=10)

(or)

(b) Imagine that you are a general Manager of a company where you need to install air conditioners, and water purifiers. Write a letter inviting quotation for the products.
