A1. Complete the chart on the life stages of fireflies: (2)
|
Fireflies are beetles and go through several life stages, starting out as an egg, then hatching into larvae. At the juvenile stage, they turn into pupae and then, finally adults. Fireflies spend most of their lives in a larval stage, hidden away. There are 2000 different species of fireflies. But they all go through a long juvenile stage and a short adult life, which is mainly about courtship, mating and reproduction. The juveniles living underground or underwater, are very different though-they're hunters, they eat snails and soft-bodied insects and they have very different habitats. Conserving them is essential for human life as fireflies are a key part of the food web. They are predators of agricultural pests. In turn, they are prey for spiders and other insects. They are completely enmeshed in the web of life. In addition, about 70 years ago, scientists unravelled the mystery of fireflies' light-producing talents. Since then, the bio-chemical reactions that fireflies experience have been used in detecting bacterial contamination in foods, testing drugs against cancer, developing drought-resistant crops. They have been used in space exploration. So fireflies give us beauty and inventions. Fireflies carry oxygen, calcium, magnesium and a natural chemical called luciferin. These react together to produce the photons. This is how the fireflies glow. Firefly tourism is growing across the world. In Maharashtra, for example, a particular species monsoon fireflies, emerge before the rains. They're beautiful and a festival is held in Purushwadi, encouraging firefly tourism. Its wonderful that people around the world go to see fireflies in their natural habitat. We need to be cautious. Too many people can disturb adult and larval habitats. Fireflies need darkness to communicate with each other and we need fireflies because they are harbingers of hope. |

उत्तर
A1.
A2. Fireflies are preserved because the biochemical processes they go through are important for detecting bacterial contamination in food and testing anti-cancer medications, among other things. Oxygen, calcium, magnesium, and luciferin are also carried by fireflies.
A3.
- different × indifferent
- experience × inexperience
- bacterial × anti-bacterial
- natural × unnatural
A4. (i) Many people can disturb adult as well as larval habitat.
(ii) to produce
A5. Insect pollinators, such as bees, help with propagation and fruit production. They are also pest predators or parasites. Aside from that, they provide honey. Bees work extremely hard. They frequently work themselves to death. This is a source of inspiration for humans. They teach us to never give up, even when the odds are stacked against us.

It is rare to find someone with good technical and communication skills. You can get far ahead of your colleagues if you combine the two early in your career. People will judge, evaluate, promote or block you based on your communication skills. Since habits form by repeating both good and bad forms of communication, learn to observe great communicators and adopt their styles and traits — in written and verbal forms. The art of listening and learning from each and every interaction is another secret recipe. Develop the subconscious habit of listening to yourself as you speak and know when to pause.
Learning what not to say is probably more important than learning what to say. As your career develops, you will realize that the wise speak less. Speak when you have value to add, else refrain. Poorly constructed emails with grammatical errors are acceptable between friends, but they should be seriously avoided while communicating formally with your seniors. Avoid any communication in an emotional state when might say things you will regret later. One unnecessary word uttered at the wrong time or place can ruin a relationship, career or even your life. Such is the power of words. If such a thing happens, you should immediately apologise, else it may haunt you for life.
Another problem to overcome is speaking too fast. Since our minds are working faster than our speech, we are inclined to speak fast. This does not necessarily mean that the person hearing it will get it any faster. On the contrary, it is always the reverse. So slow down and think before you speak. “When I get ready to speak to people,” Abraham Lincoln said, “I spend two-thirds of the time thinking what they want to hear and one-thirds of the time thinking what they want to hear and one-third thinking what I want to say.” Adding humour and wit is also essential. But realize that not all jokes are funny and observe certain boundaries. Never say anything that could offend. Remember you are not a comedian who must offend as many people as you can to be witty.
2.1 Answer the following questions briefly:
(a) Why is it necessary to have good communication skills?
(b) How can communication skills be developed?
(c) What, according to the writer, should be avoided while communicating?
(d) Why should you be careful when you tend to be humorous?

Read the following extract and answer the questions given below:
That day Reuben fold two sacks, which he took to the rambling wooden factory and sold to the man in charge of packing nails. The boy's hand tightly clutched the small five-cent pieces as he ran two kilometres home.
Near his house stood the ancient barn that housed the family's goats and chickens. Reuben found a rusty baking- soda tin and dropped his coins inside. Then he climbed into the loft of the barn and hid the can beneath a pile of sweet-smelling hay.
It was supper time when Reuben got home. His father sat at the big kitchen table, working on a fishing net. Dora was at the black kitchen range, ready to serve dinner as Reuben took his place at the table.
He looked at his mother and smiled. Sunlight from the window gilded her, shoulder-length blond hair. Five foot three, slim and beautiful, she was the centre of the home, the glue that held it together.
Her chores were never-ending. Sewing clothes for her family on the old Singer treadle machine, cooking meals and baking bread, planting a vegetable garden. milking the goats and scrubbing soiled clothes on a washboru·d. But she was happy. Her family and their wellbeing were her highest priority.
Every day after chores and school, Reuben scoured the town, collecting the burlap nail bags. On the day the two-room schoolhouse closed for the summer, no student was more delighted than Reuben. Now he would have more time to devote to his mission.

Read the following extract and answer the questions given below:
There are some glimmers of hope. I met up young Navdeep. Ahuja who along with another colleague began the innocuously named Graduates Welfare Association, Fazilka. They are bringing about change with the mandate of citizens' participation in governance and are facilitating the creation of physical and social infrastructure across 22 cities in Punjab. They have put in place a network of cycle rickshaws called Eco-cabs which can be booked through a mobile phone. They are also developing car tree zones, food and culture streets in these cities. All this is being done very efficiently and at a low cost. We need many such organizations. However, my idea of a city in 2020 is not a utopian dream. It is achievable. It has streets where people walk on wide footpaths shaded by leafy trees. Streets are usually one-third of a city's area and its most democratic segment. Public space dedicated to pedestrians reduces inequality and should be accorded priority when developing cities. Adjoining the streets should be cycle lanes where bicycles and, rickshaws can sail past smoothly. It'll have a great public transport system with buses, metro and taxis. Parking will be difficult and expensive so people will use public transport rather than cars. There will be parks and gardens and the air will be clean, as pollution levels will have dropped dramatically. And then cities will become areas of graceful living and a charmed way of life.
(1) What is the extract about?

Read the following passage and do the activities.
Galaxies are vast clusters of thousands of millions of stars, planets, gases and dust, which are held together by gravity. There are over one thousand million galaxies, and each is a very long way from its nearest neighbour.
Galaxies were formed during the Big Bang explosion about 15,000 million years ago. When this phenomenon occurred, everything that was in the universe flew out in different directions. Scientists believe that the galaxies were formed from lumps of matter that resulted. However, the process is nowhere near complete. The universe is still expanding, galaxies are still moving away from each other, new stars are still being created.
Galaxies are classified according to their shapes. There are three main types. The most common type of galaxy is The Spiral. This has several spiral arms radiating out from the center. Spiral galaxies have a large cluster of stars in their nucleus. The second type is the Barred spiral. In this type of galaxy, the spiral arms curve away from the opposite ends of a sort of bar going through the middle of the nucleus. These contain large amounts of gas and dust as well stars. The third type of galaxy is electrical. These consist almost entirely of stars and contain very little gas or dust. Some galaxies have irregular, uneven shapes and cannot be classified.
(A1) State whether the following statements are true or false. 02
(1) The most common type of galaxy is the barred spiral.
(2) Galaxies are clusters, held by gravity.
(3) Scientists do not believe in the Big Bang explosion.

‘Your father was my enemy,’ said Frederick. ‘I would have been better pleased by your brave deed if you had told me of another father?’
‘I am proud to be Sir Rowland's son,’ answered Orlando angrily,’ and I would not change my place to be the heir of this dukedom.’
The Duke and his lords went away, leaving Orlando alone with Rosalind and Celia. Celia was angry with her father for speaking so unkindly to Orlando. ‘Would I have done this in my father’s place?’ she said to Rosalind.
‘My father loved Sir Rowland as much as his own soul,’ Rosalind said to Celia, ‘and all the world agreed with him. If I had known that his young man was Sir Rowland’s son I should have begged him with tears not to take so great a risk.’
‘Let us go and speak to Orlando,’ said gentle Celia. ‘I am ashamed of my father’s rude and angry words.’
The two girls went up to Orilando and praised him for his bravery. Rosalind took a gold chain from her neck and gave it to him. ‘I would like to give you more’, she said, ‘but I am not rich.’ Then she and Celia went away.
Orlando, however, could not forget them. He had already fallen in love with the fair Rosalind, but he could not stay at the Duke’s palace. His friends warned him that Frederick was angry and jealous of him. They told Orlando to leave the dukedom, because the Duke meant to do him harm.

Urea is a major product of nitrogen metabolism in humans. It is eliminated from the body mainly by the kidneys through urine. Urea levels in body fluids, such as blood and saliva, rise drastically under certain kidney dysfunctions. Heart failure, hypovolemic shock, gastrointestinal bleeding, and severe infections can also lead to a rise. Thus urea in blood and saliva provides key information on renal function and helps diagnose various disorders. Most methods for estimating urea in body fluids are based on colorimetry. These methods are time-consuming and involve painful blood extraction. Collecting saliva is non-evasive and research has correlated salivary and blood urea levels. Recently scientists from the IIT-D and the AIIMS, New Delhi successfully developed a smartphone-based optical biosensor to detect urea in saliva. To fabricate the sensor, they directly immobilised the urease enzyme with a pH indicator on a filter paper-based strip. As a response to the urea on saliva, the paper strip changes colour. The red, green and blue levels help measure urea concentration. The scientists used the slope method, sensor response change per unit time, instead of the differential method, the difference in sensor response between two-time intervals, to increase sensitivity and eliminate interference by variations in ambient light. The team clinically validated spiked saliva samples and samples from healthy volunteers. The smartphone application with paper strip can even be operated by non-professional with limited training. This saves time and cost spent on bulky spectroscopic procedures. The report can revolutionise the medical screening of large populations. And such mass screening of diseases would boost national health. |
A2. Complete the following sentence using the correct alternatives from those given below :
Two objectives to conduct the research are ___________ .
(i) The colorimetry method used to estimate urea in body fluids consumes more time.

Read the passage given below :
Globalization
Globalization is the way to open businesses, improve technological growth, economy, etc, at the international level for all countries. It is the way in which manufacturers and producers of the products or goods sell their products globally without any restriction. It provides huge profits to the businessmen as they get 1ow cost labor in poor countries easily. It provides a big opportunity for companies to„ deal with the worldwide market.
Globalization helps to consider the whole world 'as a single market. Traders are extending their areas of business by treating the world as a global village. Earlier till the 1990s, there was a restriction on importing certain products that were already manufactured in India like agricultural products, engineering goods, food items, and toiletries. However, during the 1990s there was pressure from. the rich countries on the poor and developing countries to allow them to spread their businesses by opening their markets. In India, the globalization and liberalization process was started in 1991.
After many years, globalization brought about a major revolution in the Indian market when multinational brands came to India and started delivering a wide range of quality products at cheap prices. Prices of good quality products came down because of the cutthroat competition in the market.
Globalization and liberalization of the businesses in India have flooded the market with quality foreign products but have affected the local Indian industries adversely to a great extent resulting in job loss to poor and uneducated workers. Globalization has been a bonanza for the consumers, however, a loss to the small-scale Indian producers.
Globalization has had some very positive effects on the Indian consumer in all sectors of society. It has affected the Indian students and education sector to a great extent by making study books and a lot of information available over the internet. The collaboration of foreign universities with Indian universities has brought about a huge change in the field of education.
Globalization of trade in the agricultural sector has brought varieties of quality seeds that have disease resistati8e; property. However, it is not good for the poor Indian farmers because the seeds and agricultural technologies are costly.
It has brought about a huge revolution in the employment sector by the spread of businesses like cottage, handloom, carpet, artisan carving, ceramic, jewelry, and glassware, etc
(a) What is globalization?
(b) Write any two advantages of globalization.
(c) What was the pressure from the rich countries in the 1990s?
(d) What is the effect of multinational brands entering the Indian market?
(e) How are the prices of quality products affected due to globalization?
(f) How have foreign products affected the local industry adversely?

A1. List the benefits of Yoga (02)
- ______
- ______
- ______
- ______
We give undue importance to our health and the treatment of diseases. A large number of medicines treat only the symptoms of the disease, and not the root cause. In fact, the cause of many chronic ailments is still being researched. It is here that Yoga therapy comes to our assistance. Yoga emphasizes the treatment of the root cause of an ailment. It works in a slow, subtle and miraculous manner. Modern medicine can claim to save a life at a critical stage, but, for complete recovery and regaining of normal health, one must believe in the efficiency of Yoga therapy.
The Yogic way of life includes a code of ethics, regulations, discipline, combined with prayer and meditation. Even a discussion of these subjects helps one relieve mental tensions and change attitudes. Simple Asana has helped to stretch and relax the whole body and release tensions. The sincere practice of Yoga postures is beneficial, for the mind and body.
The continued practice of Yoga has a profound effect on the inner dimensions of life. Yoga aims at developing mental, physical, spiritual, and emotional facilities. Other forms of physical exercises, like aerobics, assure only physical well-being. They have little to do with the development of the soul and mind.
