Briefly write what you learn about Santosh Yadav’s parents.
Answer:
Santosh Yadav’s parents were affluent but conservative people. Her father was a wealthy landlord from Joniyawas village of Rewari District in Haryana.

They yielded to their daughter’s demands because they loved her dearly, and knew that she was sensible enough to have chosen a correct and a rational path. Thus, Santosh got full support from her parents, which in the long run helped her reach to the top.

Question 2.
Write a brief note on Santosh’s journey from her local village school to the Nehru Institute of Mountaineering at Uttarkashi.
Answer:
Born in an affluent but traditional and conservative landowners’ family in a small village of Rewari district in Haryana, Santosh was a rebel from early childhood. The local village school, but when her parents insisted she get married at the age of sixteen, she refused as she wanted to get a proper education first.

She got admission in Delhi school, despite her parents’ reluctance to send her there and informed them politely that she would earn by working part time. Santosh persuaded her parents to send her to Jaipur for higher studies after finishing high school. She got admission in Maharani College, Jaipur. She got a room in Kasturba Hostel which faced the Aravalli hills. She used to see the villagers going up the hill and disappearing.

This aroused her curiosity about the mountains. One day, when Santosh went near the hills, she met some climbers. They encouraged her to take to climbing. This whetted her interest in climbing and she saved money and took admission in Nehru Institute of Mountaineering at Uttarkashi.

Answer:
Born to conservative parents, Santosh did not want to let the norms of the patriarchal, gender-biased and rigidly conventional society dictate her life. Though her name means contentment, Santosh was not always content with her place in a traditional way of life and wanted to live life on her own terms. In fact, she believed that if she chose a correct and a rational path, others would have to change and align themselves to her choices, not her.

She wore shorts instead of traditional dresses as a child. Santosh resisted the pressure to get married at the young age of sixteen, declaring that she would not marry at all if denied proper education. Defying tradition, she got enrolled in a school in Delhi.

When her parents refused to pay for her schooling, she informed them that she would work part-time to manage her school fees. Seeing their daughter’s determination, her parents had to give in. Taking up mountaineering as her career was also an independent decision. However, she tried her best not to hurt her parents and wrote a letter of apology to her father for not having sought his permission before joining the Nehru Institute of Mountaineering in Uttarkashi. Thus, despite all odds, Santosh chose for herself a path which was absolutely unthinkable and unheard of for girls in an orthodox society.

And the right moment came when she turned sixteen. At sixteen, most of the girls in her village used to get married.

Santosh, too, was under pressure from her parents to do the same. Instead of giving in, she opposed her parents’ decision to marry her off at the early age of sixteen and got herself enrolled in a school in Delhi. When her parents refused to pay for her education in the city, she told them politely that she would earn money for her fees by working part-time. She politely but firmly made it clear that she was determined to overcome all obstacles.

Finally, her parents had to surrender. Her decision to take up mountaineering as a career was also handled very boldly by her. She took admission in Uttarkashi’s Nehru Institute of Mountaineering without seeking the permission of her parents leaving them with no choice but to accept her decision. Thus, Santosh rebelled against the orthodox, conservative system in a quiet but firm way.

Although both girls were supported by their respective parents, Santosh, at times, had to struggle to make her conservative family agree to her decisions, while Maria’s parents were willing to make any sacrifice to help Maria succeed. However, both the young girls had to sacrifice the loving and protective environment of their homes in order to train for their passion.

Both the women had unwavering determination, physical and mental strength, and undivided focus on their goals. They both rose to the number one position in their respective areas within a short span of four years. While Sharapova moved from the frozen Siberia to the plains of Florida, Yadav moved from the plains of Rewari to the frozen Mount Everest. But both of them are devout patriots and their love for their country remains constant.

Question 2.
Write two points of difference between asexual and sexual types of reproduction. Describe why variations are observed in the offspring formed by sexual reproduction.  [NCERT Exemplar]
Answer:
Asexual Reproduction:

  1. Single parent is involved.
  2. No fusion of gametes occur.
  3. Progeny is genetically identical to the parent.
    For example, Fission in Amoeba

Sexual Reproduction:

  1. Two parents are involved.
  2. Fusion of gametes occurs.
  3. Variations occur in the progeny.
    For example, Human beings

Fusion of gametes occurs during sexual reproduction. The gametes contain the same number of chromosomes but their DNA is not identical so variations arise among the offsprings.

Question 3.
Distinguish between pollination and fertilisation. Mention the site and product of fertilisation in a flower. Draw a neat, labelled diagram of a pistil showing pollen tube growth and its entry into the ovule.   [NCERT Exemplar]
Answer:
Pollination: The transfer of pollen grains from the anther to the stigma of a flower is called pollination.

Question 4.
Distinguish between a gamete and zygote. Explain their roles in sexual reproduction.  [NCERT Exemplar]
Answer:
The sex cell or germ cell in sexual reproduction is called gametes. There are two types of gametes, male and female. A male and a female gamete fuse with each other during fertilisation to form a zygote.

The gametes possess characters of their parents in their DNA and their fusion brings characters of both parents into one zygote cell. Zygote is the first cell of the next generation which divides to form an embryo which subsequently grows into a new individual.

Question 5.

Question 57.
Give a chemical test to distinguish between :
(i) Ethane and ethene
(ii) Ethanol and ethanoic acid
(iii) Soaps and detergents.
Answer:
(i) Ethene decolorises the yellow colour of bromine water while ethane does not.
(ii) Ethanoic acid gives a brisk effervescence with sodium hydrogen carbonate while ethanol does not.
(iii) Soaps form curdy white precipitate or scum with hard water while detergents do not form any precipitate.

Question 58.
(a) What are homologous series of compounds ? List any two characteristics of homologous series.
(b) What would be observed by adding a 5% solution of alkaline potassium permanganate drop by drop to warm ethanol taken in a test tube ? (c) Write the name of the compound formed during the chemical reaction. How would you distinguish experimentally between an alcohol and a carboxylic acid on the basis of a chemical property.
Answer:
(a) Homologous series represent different families of organic compounds into which these are divided. Two characteristics of homologous series are listed.

  1. All the members in a particular homologous series of family have the same characteristic functional group. For example, in organic acids, the functional group is carboxyl group (—COOH).
  2. Any two consecutive members in a particular family have the same common difference of CH2 in their molecular formulae. For example, the first three members of the family of alkanes are : CH4 (methane), C2H6 (ethane) and propane (C3H8).

(b) On adding a 5% solution of alkaline potassium permanganate to ethanol, it will be oxidised to ethanoic acid.
The pink colour of the solution will get discharged upon warming.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 27
(c) A carboxylic acid gives a brisk effervescence when an aqueous solution of sodium hydrogen carbonate (NaHCO3) is added to it. This is due to the evolution of CO2 gas. However, alcohol will not give any reaction.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 28

Question 59.
(a) How are carboxylic acids different from mineral acids from ionisation point of view ?
(b) Describe an activity to show how ethanoic acid reacts with sodium carbonate. Name the gas evolved. How can it be tested ?
(c) State the principle on which the cleansing action of soap is based.
Answer:
(a) Carboxylic acids (organic acids) are less ionised in solution as compared to mineral acids (HCl, HNO3, H2SO4 etc.) Due to this reason, these are weaker acids than the mineral acids.
(b) Take a small volume of ethanoic acid in a tube. Add a few drops of sodium carbonate (Na2CO3) solution prepared in water to the tube. A colourless gas with brisk effervescence will evolve. When the gas is passed through lime water, it will become milky.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 29
(c) The cleansing action of soap is based on its tendency to act as a bridge between water and oil drops containing dirt particles. As a result, oil and water get mixed. They form a stable emulsion also called micelle. This helps in removing oil drops containing dirt particles from clothes. The clothes become clean.

Question 60.
(a) Distinguish between esterification and saponification reactions of organic compounds.
(b) With the help of a labelled diagram, describe an activity to show the formation of an ester.
Answer:
(a) In the esterification reaction an acid reacts with alcohol in the presence of cone. H2SO4 to form an ester with a pleasant or fruity smell. For example,
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 30
Saponification is quite different from esterification because in this case an ester reacts with an alkali (NaOH or KOH) to form salt of acid and alcohol. For example,
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 31
(b) For the activity,
Esters can be easily formed in the laboratory also. Take equal volumes of ethyl alcohol and glacial acetic acid (say 2 mL) alongwith a few drops of concentrated sulphuric acid in a test tube. In the mean time, warm water in a beaker as shown in the figure. Keep the test tube in warm water for some time. You will experience a pleasant smell. This shows that ethyl acetate (ester) has been formed in the reaction.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 32
Esters as pointed, are pleasant smelling compounds. These are therefore, commonly used as flavouring agents and also in perfumes. When an ester is reacted with water in the presence of a dilute acid like dilute HCl, acid and alcohol are formed as the product. The reaction is called ester hydrolysis.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 33
Ester hydrolysis is the reverse of esterification reaction.
When an ester is reacted with an aqueous solution of base like NaOH or KOH, the product is an alcohol and salt of the acid. For example,Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 34

The reaction is known as saponification reaction because it is the basis for the formation of soap.

Question 61.
An ester has the molecular formula C4H8O2. Write its structural formula. What happens when this ester is heated in the presence of sodium hydroxide solution ? Write the balanced chemical equation for the reaction and name the products. What is a saponification reaction ?
Answer:
For the molecular formula C4H8O2, two isomeric esters are possible which differ in structural formulae.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 35
Both will react with sodium hydroxide upon heating to form the sodium salt of the acid and alcohol.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 36
Both the reactions are the examples of saponification reactions. In these, an ester reacts with an alkali upon heating to form corresponding salt and alcohol.

Question 62.
Two carbon compounds ‘A’ and ‘B’ have the molecular formula C3H8 and C3H6 respectively. Which one of the two is most likely to show addition reactions ? Justify your answer. Explain with the help of a chemical equation, how an addition reaction is useful in vegetable ghee industry.
Answer:
The compound ‘A’ with formula C3H8(propane) is a saturated hydrocarbon and corresponds to general formula CnH2n+2. The compound ‘B’ with formula C3H6 (propene) is an unsaturated hydrocarbon and corresponds to general formula CnH2n. It has a double bond (C=C) and is therefore, unsaturated.
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 37
The compound ‘B’ will take part in the addition reactions. As a result, double bond will change to single bond. For example,
Carbon and its Compounds Class 10 Important Questions Science Chapter 4 image - 38
The addition reaction is quite useful in the hydrogenation of oils i.e., to convert edible oils like ground nut oil and cotton seed oil which are unsaturated in nature into solid fats which are of saturated nature.

His First Flight Summary in English

‘His First Flight’ written by Liam O’ Flaherty is a story of a young seagull who is afraid of flying. A family of seagulls lived on a ledge. A young seagull is left alone as he is afraid to fly and is one among the slow learners. All that this young seagull needed was motivation. By way of punishment, his family left him alone on the ledge and flew away. They upbraided him, taunted him for cowardice and even threatened to let him starve. He remained hungry for twenty-four hours and was unable to shed off his fright of flight. He cried begging his mother to bring him some food.

She picked up a piece of fish in her beak and flew across him and stood just in front of him. The piece of fish in her beak was almost within the reach of his beak. The young seagull was mad with hunger. He dived at the fish. The next moment he found himself falling outwards and downwards into space. Instinctively, he spread his wings and flapped them. He soared upwards and all his fear is gone. It was a joyous moment for his family. He forgot that he was ever afraid of flying.

His First Flight Summary Questions and Answers

Question 1.
For how long had the seagull been alone?
Answer:
The seagull had been alone for twenty-four hours.

Question 2.
Why did the seagull not go with the rest of his family?
Answer:
The seagull did not go with the rest of his family because he was afraid to fly.

Question 3.
(i) What were the ways the seagull had thought of to join his family?
(ii) Did he try any one of them?
Answer:
(i) The seagull thought of joining his family without having to fly. He ran from one end of the ledge to the other. The ledge ended in a steep fall in precipice. He thought of walking upto them but there was a deep chasm between him and them.
(ii) No, he didn’t try anyone of them.

Question 4.
Did the seagull think the sea was like a land? Pick out the words from the text that suggest this.
Answer:
Yes, the seagull thought the sea was like a land. He landed on the sea. When his legs sank into it, he screamed with fear and tried to rise again flapping his wings. This clearly indicates that he thought the sea was like a land.

Question 5.
(i) When did the seagull’s flight begin?
(ii) Where did it end?
Answer:
(i) His flight began when he was falling outwards and downwards into space. His wings spread outwards. Now, he was not falling headlong. He was moving gradually downwards and outwards.
(ii) His flight ended floating on the sea.

Question 6.
When did the seagull get over his fear of the water?
Answer:
The seagull thought the sea was like a land. When he landed on the sea, his feet sank into it. He was seized with fear. He was too tired to rise again. His belly touched the water and he sank no further. Now, he was floating on the sea. He had got over his fear of the water.

Question 7.
Do you sympathise with the seagull? Give reasons.
Answer:
Flying is a natural instinct of birds. But the young seagull develops a fright of flight. We sympathise with him because he has to suffer a lot before he gets over his fear of flying. He has to bear the taunts of his family. He has to go without food for twenty-four hours.

Question 8.
How did the seagull express his excitement when he saw his mother bringing food for him?
Answer:
The seagull was very hungry. When he saw his mother bringing food for him, he was greatly excited. He expressed his excitement by uttering a joyful scream. He leaned out eagerly. He tapped the rock with his feet. He tried to get nearer to her as she flew across. ‘

Question 9.
How did the young seagull’s parents teach him the art of flying?
Answer:
Birds have a natural instinct to fly. However, some birds, like the young seagull in the story are afraid to fly. Then their parents teach them how to fly. The seagull’s parents fly about with their children curveting and banking and soaring and diving and thus, perfecting them in the art of flying.

Body Movements Class 6 Extra Questions Long Answer Type

Question 1.
What is a muscle? Explain how it helps in movement.
Answer:
A muscle is the fibrous tissue in the body that has an ability to contract (when asked to do so by the brain). When a muscle contracts, it shortens (becomes smaller). Muscles are attached to the bones of our skeleton through a long fibre called tendon.

Muscle always work in pairs. When one muscle of a pair contracts, then the other muscle of a pair is relaxed. A contracted muscle can come back to its original position only when the other muscle of the pair contracts.

Question 2.
How many types of joints are there? Explain each of them.
Answer:
The main types of joints in the human are:

  1. Hinge joint
  2. Ball and socket joint
  3. Pivot joint
  4. Fixed joint

(i) Hinge joint: A hinge joint is the joint which allows movement in only one direction, i.e., forward and backward.
(ii) Ball and socket joint: In the ball and socket joint, one end of the bone has a round shape like a ‘ball’ which fits into a ‘socket’ (hollow space) in the other bone. Such joint allow movement in all directions, e.g., shoulder and hip joints.
(iii) Pivot joint: In a pivot joint, a cylindrical bone turns in a ring-type bone. The pivot joint allows movement in forward and backward and right and left, e.g., neck joint.
(iv) Fixed joint: In some joints, the bones are held so tightly together that they cannot move at all.

Question 3.
What is skeleton? State its functions.
Answer:
The skeleton consists of skull, backbone, ribs, breastbone, shoulder bones, hip bones, arm bones and leg bones. The human skeleton consists of a strong backbone which has skulls at its top end.

Following are the functions of skeleton:

  1. The skeleton holds the whole body together and gives it a shape.
  2. It protects many delicate internal organs of the body from damage.
  3. It provides numerous points for the attachment of the muscles of the body.
  4. Along with muscles, the skeleton helps in the movement of body parts and locomotion.

Question 4.
What is dislocation and fracture of bone? What precaution should one take when one gets a fracture?
Answer:
Any careless sudden movement a jump, fall or knock may cause an injury to the skeleton. It may be a dislocation or a fracture. In case of dislocation the bones at the joint are dislodged from their normal position. The ligaments may be torn apart or injured causing pain and swelling.

A fracture is a break in the bone. The break may be of a hair line crack or serious break in one or more points. Fracture also causes pain and swelling. In all these cases, the patient should soon be taken to a doctor or hospital.

Following precautions should be taken when one gets a fracture:

  1. Never try to reset the bones on your own.
  2. Place the injured part in a comfortable position.
  3. Care should be taken to avoid jerk or movement of the injured part.

Question 5.
How a bone is formed? What kind of food should we take for proper growth and upkeep of bones?
Answer:
Before our birth the skeleton forms a soft and elastic piece of cartilage. Some of these cartilages, not all, are changed to bones. With the deposition of a substance containing calcium and phosphorus, the bones become hard and strong.

When a baby is born, its skeleton is soft. With the growth and development, bones become hard. At old age, the bones become hard and brittle.

For proper growth and upkeep of bones we need to take food which are rich in calcium and phosphorus, vitamins and proteins. Milk, curd, fruits, vegetables and eggs contain the needed nutrients.

Question 3.
How many bones are there in a newborn baby? How it becomes 206 bones by adulthood?
Answer:
There are approx. 305 bones in a newborn baby. Most of the bones fuses together to form single bone by the time of adulthood. So, it become 206 bones by adulthood.

Question 4.
What do you understand by brittle bone?
Answer:
By the time a person grew older, his body may reabsorb calcium and phosphate from the bones instead of keeping these minerals in the bones. Thus bones become weaker and can break easily without any obvious injury.

Question 5.
What do you think will happen if our body have as many number of movable joints as the number of bones?
Answer:
Too many numbers of movable joints can also make our work difficult. We may not walk or do our daily chores properly and easily.
