Banbir had a naked sword in his hand.

(i) The classification helps us to decide which of the available energy sources need to be conserved to ensure their availability for future generations.
(ii) The classification helps us to look for alternative sources of energy like solar and wind energy. It has, therefore, accelerated the pace of development of technologies suitable for harnessing new sources of energy.

Classification of resources helps us in deciding the kind of resource we should use judiciously and wisely. The resource that is not limited and present in plenty can be used as an alternate for the limited resources. It also helps us to know the importance of using renewable source of energy.

An electromagnet works on the magnetic effect of current.

The conductor experiences a force and the direction of this force is given by Fleming's left-hand rule.

When a current-carrying conductor is placed in a magnetic field, a mechanical force is exerted on the conductor which can make the conductor move.

Panna was a brave and courageous woman. In the time of danger she did not lose heart. She decided quickly what she should do to save the Prince’s life. She did not hesitate to sacrifice the life of her own son. She showed utmost courage and presence of mind. She was ready to do anything to keep her promise. Her resolute mind and loyalty deserve our appreciation.

Renewable sources: wind, tides, Sun, biomass, hydro energy
Non-renewable sources: coal, petrol, CNG

By classifying sources of energy as renewable and non-renewable:

• We can have a knowledge of how many sources are left and the proper ways they can be used so that we can pass them to our future generations.

• We can look for different alternates of the fast depleting non-renewable resources of energy.

As per Flemings left hand rule the direction of magnetic field is down.

The force experienced by a current-carrying conductor placed in a magnetic field is largest when the direction of current is at right angles to the direction of the magnetic field.

Yes, we have seen many types of plants in the garden, out of which some are very small, some are medium sized and some are very big trees.

When the length of current-carrying conductor and direction of magnetic field are perpendicular to each other, the maximum force is experienced by the current-carrying conductor.

1. At present, wheat crop is grown in the farm. 

2. This crop is sown in November – December. 

3. In April – May. 

4. The time duration between sowing and harvesting the crop is 5 – 6 months. 

5. Life span of Jowar, Mustard, Millet and Maize is one year. 

6. Carrot, sugarcane, cabbage, onion. 

7. Neem, pine, banyan, mango, pipal etc.

If the direction of magnetic field and flow of electric current are mutually perpendicular then force experienced by a current-carrying conductor in a magnetic field is largest.

No, some plants are short lived from 4 to 6 month, some are of 1 – 2 years and some are long lived for many years.

Various types of flowering and non – flowering plants grown in garden or pots:

Yes, on the basis of the habitat plants are of two types : 

1. Aquatic plants

2. Terrestrial plants

The process by which leaves of green plants prepare food material in the presence of sunlight, carbon dioxide, water and chlorophyll is called photosynthesis.

Plants are classifed on the basis of their size into three 

The smallest flowering plant is Wolffia. The largest tree in thickness is General Sherman and its scientific name is Sequoia dendron giganteum. The tallest tree is Eucalyptus which is also known as ‘safeda’ in Hindi.

Yes, they perform transpiration.

No, All plants have not similar roots. It is not possible to uproot a big tree.

No, they don’t look alike they are of different size and shapes.

In some cases, the structure of roots is similar and in some cases it is dissimilar.

Yes, the storage of food occurs in the stem also e.g., potato and sugarcane. Stem performs vegetative reproduction.

Carrot and radish are such type of root.

To ensure that people are not cheated by vendors and that they get the right quantity of vegetables for the money paid.

The Urban local government bodies in the city are working towards infrastructural development of the city

To take steps towards creating a healthy society and contain the spread of epidemics.

I will write a letter to the editor and express my views about the same. I will explain why the action may not have the desired effect and suggest an alternative measure.

The corporation wants to ensure that the environment is conserved and preserved and that the environmental balance is not disturbed in the name of progress.

1. Eurythermal animals : Goat, man, cow, crab, bivalves, etc. 

2. Stenothermal animals : Insects, reptiles, snakes, fishes, etc.

3. Eurythermal plants : Roses, daisies, oak trees, some fruits and vegetables. 

4. Stenothermal plants : Croton, Bougainvillea, Frangipani, vines and orchids, some other fruits and vegetables

1. Global temperature rise or global warming is having great impact on natural habitats. 

2. Aquatic habitats like oceans are worst affected as 90% of extra heat enters marine waters. These elevated temperatures cause adverse effects on marine habitat. 

3. Coral reefs are also affected due to increased temperature. It causes bleaching of coral reefs. Fish populations are adversely affected. 

4. Due to rising temperature, the tundra regions and polar regions are showing melting of snow. These habitats are disappearing and the animals from these areas such as polar bears are on the verge of extinction. Increased temperatures also cause desertification of the once green habitats. 

5. Nearly 50% of the species are under threat of extinction due to climate change. Global warming and climate change thus reduces biodiversity. 

6. Every plant and animal species is adapted to a specific temperature conditions. But due to global warming and associated climate change, these species are affected. Some species show migrations to cooler places. 

7. Temperatures also alter the life cycles of plants and animals. When temperatures rise, many plants grow rapidly and bloom earlier in the spring and survive longer into the fall. Some animals leave hibernation sooner.

Different abiotic factors make great variations in the physical and chemical conditions of different habitats. 

The most important abiotic factors are temperature, water, light and soil. These abiotic factors act with the resident biotic factors in that habitat. Biotic components such as pathogens, parasites, predators and competitors keep on interacting continuously. All such interactions cause variations in different habitats.

It is important to take permission from the Municipal authorities before construction of building.

c. The following forest plants controls the light conditions at the ground Tall trees.

The urban local government bodies ensure that proper facilities are provided to the people for rest, recreation and general well being.

The local gemment bodies take steps to ensure that water, a scarce resource, is not wasted.

Waste management is given priority by the local government bodies.

The local government bodies take steps to ensure that all citizens including senior citizens experience safety and security. They want to ensure that the senior citizens lead a life of dignity.

He will not be able to distinguish between red and green signal on road. This may lead to an accident.

a) The judge showed wisdom and intention to search for the truth.

b) 

1. DNA fingerprinting involves identifying differences in some specific regions in DNA sequence called as repetitive DNA. 

2. Depending on base composition (A: T rich or G:C rich), length of segment, and number of repetitive units, the satellite DNA is classified into many categories,(Micro-satellites, mini-satellites etc). 

3. These sequences normally do not code for any proteins, but they form a large portion of human genome. These sequence show high degree of polymorphism and form the basis of DNA fingerprinting. 

c) 

(i) isolation of DNA, 

(ii) digestion of DNA by restriction endonucleases, 

(iii) separation of DNA fragments by electrophoresis, 

(iv) transferring (blotting) of separated DNA fragments to synthetic membranes, such as nitrocellulose or nylon, 

(v) hybridisation using labelled VNTR probe, and 

(vi) detection of hybridised DNA fragments by autoradiography.

There are several problems in cities: Shortage of housing, insufficient space, traffic congestion, problem of waste disposal, increase in crime and a large proportion of slum population.
