(a) The writer is unable to imagine a world without tigers as the power and beauty of these animals is indisputable. They are an integral part of the ecosystem and are a major link in the food chain. (b) We can write to our government regarding the merciless killing of tigers. We can write to the various governments of tiger countries and urge them to protect tigers. Penalties for killing tigers should be strongly enforced. (c) Extremist groups are banning all exotic animal from captivity. This could lead to the end of many species of animals for species whose numbers are extremely low such as clouded leopard. Caring by private owners are rapidly becoming the last havens to preserve them. (d) This is possible because saving tigers from extinction is a global issue but each of us can play a part, by writing to the concerned government to protect these beautiful cats.

A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.  A magnetic field is produced by moving electric charges and intrinsic magnetic moments of elementary particles associated with a fundamental quantum property known as the spin.  Magnetic field and electric field are both interrelated to each other and are components of the electromagnetic force, one of the four fundamental forces of nature.

The poet describes the dragon that it had big sharp teeth and spikes on top. This means that its skin was pointed on the top. On the lower part it had scales which were bony plates to protect the skin. His mouth has been compared to a fireplace because it is assumed that dragons can release fire from the mouth. Even his nose is compared to a chimney which is used to pass out smoke. His feet are like a sharp knife i.e. a dagger

Democracy and economic growth and development have had a strong correlative and interactive relationship throughout history. Democratization of a country from a non-democratic regime is usually preceded by a fall in GDP, and a volatile but expected growth in the long run, While on the other hand authoritarian regimes experience significant growth at the beginning and decline in the long run. The cause of such behavior is that non-democratic regimes, mainly authoritarian ones, are more effective at implementing decisive policies and choices as well as solving ethnic and sub-national conflicts, but are unsustainable in the long run as there is more incentive to extract money from society which in turn leads to less prosperity. Democratic regimes revolve around institutions and policies which lay the foundations, through which principles of liberty and equality are designed and followed, thus directly or indirectly affecting firms or individuals who benefit from the directives and increase their growth, which in turn has a positive impact on economy.

Griffin was lawless because he had committed many anti-social deeds for which he never felt guilty. He set fire to his landlord's house and ran away, he stole ' foodstuffs and clothes from a London store, stole other goods from a theatrical company and also stole money from a clergyman's house to pay his bills.

Despotic rule of Louis XVI: He became the ruler of France in 1774. He had drained the financial resources of France in wars. For the cost of his regular extravagant expenses, he increased taxes which were paid by the third estate.
Division of French society: The French society was divided into three estates; first, second and third estates, respectively. Among them, First and Second Estates had 10 per cent of the total population and were the clergy and nobles. They enjoyed all privileges. Rest of the 90 per cent was of the third estate, which paid all kinds of direct or indirect taxes. This kind of discrimination led to the revolution by the third estate.
Rising prices: The population of France had increased. This resulted into more demand of food grains. So the price of bread rose rapidly, which the poor could not afford to buy. So the gap between the rich and poor widened.
Inspiration of the philosophers: Philosophers like John Locke, Jean Jacques Rousseau and Montesquieu propagated the ideas of having a society where people would enjoy freedom, equal laws and equal opportunities. Their ideas inspired the people of France to realise their dreams.
Role of middle class: The 18th century witnessed the emergence of social groups termed as middle class, who earned their wealth through an expanding trade of the manufactured goods, being exported. There were other professionals also like lawyers, administrative officials who were all educated. They believed that no group in society should be privileged by birth.

Following are the social, economic, political and intellectual causes of the French Revolution:

Social -  In France, the clergy and the nobility formed the first two Estates and were the most privileged classes in the French society. They were exempt from payment of taxes to the State. On the other hand, the Third Estate that consisted of peasants and workers burdened with excessive taxes with no political and social rights. As a result, they were full of discontent.

Economic - As a result of a numerous wars waged by Louis XVI the State coffers were empty. The situation was made even more complex by France’s involvement in the American War of Independence and the faulty system of taxation.

Political - The Bourbon king of France, Louis XVI was an extremely autocratic and weak willed king who led a life of obscene luxury. This led to a lot of disenchantment among the masses who then were leading life of extreme poverty and widespread hunger.

Intellectual - The 18^th century was marked by a conscious refusal by French thinkers of the ‘Divine Rights Theory’. Philosophers like Rousseau, rejected the paradigm of absolute monarchy and promulgated the doctrine of equality of man and sovereignty of people.

Excretion is a biological process by which an organism get rid of excess or toxic waste products of metabolism.

Excretion removes unwanted by-products of metabolism,toxic chemical substances,regulate the ionic concentration of body fluids,regulates water content of body,regulate pH of body fluids.

In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redox equation.

Steps To Balance Ionic Equations

1. Write the net ionic equation for the unbalanced reaction. ...
2. Separate the net ionic equation into the two half-reactions. ...
3. For one of the half-reactions, balance the atoms except for O and H. ...
4. Repeat this with the other half-reaction.
5. Add H2O to balance the O atoms. ...
6. Balance charge.

In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Hydrocarbons are the principal constituents of petroleum and natural gas. They serve as fuels and lubricants as well as raw materials for the production of plastics, fibres, rubbers, solvents, explosives, and industrial chemicals.

Disobedience can have a variety of causes. At times, it is due to unreasonable parental expectations. Or it might be related to the child's temperament, or to school problems, family stress, or conflicts between his parents.

Civil disobedience is the active, professed refusal of a citizen to obey certain laws, demands, orders or commands of a government. By some definitions, civil disobedience has to be nonviolent to be called "civil". Hence, civil disobedience is sometimes equated with peaceful protests or nonviolent resistance.

We have given that
Sum of the first n terms = 4n – n²
⇒ S_n = 4n – n²
Put, n = 1, then
S₁ = 4(1) – (1)² = 4 – 1 = 3
⇒ d₁ = 3
Hence, the first term is
Put n = 2, then
S₂ = 4(2) – (2)²
= 8 – 4 = 4
Hence, the sum of two terms is 4.
Now, second term = S₂ – S₁ = 4 – 3 = 1
Put n = 3, then
S₃ = 4(3) – (3)²
= 12 – 9 = 3
Third term = S₃ – S₂ = 3 – 4 = –1
Put n = 9, 10
S₉= 4(9) – (9)²
= 36 – 81 = –45
S₁₀= 4(10) – (10)²
= 40 –100 = –60
∴ Tenth term = S₁₀ – S₉
= – 60 – (–45)
= – 60 + 45 = –15
Now, S_{n –1} = 4(n – 1) – (n – 1)²
= (4n – 4) – (n² + 1 – 2n)
= 4n – 4 – n² – 1 + 2n
= 6n – n² – 5
∴ nth term = S_n – S_{n – 1}
= (4n – n²) – (6n – n² – 5)
= 4n – n² – 6n + n² + 5
= 5 –2n
