The organisation of an organism is as follows- Cell~Tissue~Organ~Organ system~Body Basically the cells are made up of atoms and molecules. Therefore if there are life processes then there must be activities at cell level which defines the necessity of invisible molecular movement for life.

The movement of various molecules that cannot be visible with naked eye is invisible movement of molecules. ... Hence, molecular movement is very necessary for life as it provides energy , transport food and water need for respiration and many more.

The Prudential Reason for power sharing is the precautionary measure. This reason for power sharing helps to reduce the possibility of conflict between social groups.
Reserved Constituencies for minorities and women in Assemblies and Parliament is the best examples of prudential reason of power sharing in India.
The Moral Reason of power sharing is the very spirit of democracy. Here, people have a right to be consulted on how they are to be governed. Decentralisation of powers in India is the best example of moral reason of power sharing.

State one prudential reason and one moral reason for power sharing with an example from the Indian context. Answer: Prudential Reason: Power sharing helps in reducing the conflict between various social groups. ... Maintaining the spirit of democracy is considered as the moral reason for power sharing.

A Rapid increase in population is a reason for the overuse of resources. It leads to over-consumption of resources making them scarce.

The increasing population is one major reason for the overuse of resources. The increase in population is multi-fold as compared to the increase in resources as they are limited. It leads to over-consumption of resources making them scarce.

gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects

Human activities which are mainly responsible for land degradation in India, are deforestation, overgrazing, mining and quarrying have contributed significantly in land degradation.

1. Mining: Mining sites are abandoned after excavation work is complete leaving deep scars and traces of over-burdening.
2. Deforestation: Mining and other types of land requirements have led to deforestation which caused has severe land degradation.
3. Over-irrigation:It is also responsible for land degradation. Irrigational water logging leads to increase in salinity and alkalinity in the soil.

Answer. (i) Mining: Mining sites are abandoned after excavation work is complete leaving deep scars in states such as Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha. ... (iii) Overgrazing: Overgrazing in states such as Gujarat, Rajasthan, Madhya Pradesh and Maharashtra is a huge cause of land degradation.

Stephen Hawking was regarded as one of the most brilliant theoretical physicists in history. His work on the origins and structure of the universe, from the Big Bang to black holes, revolutionized the field, while his best-selling books have appealed to readers who may not have Hawking's scientific background. Hawking died on March 14, 2018.

British cosmologist Stephen William Hawking was born in England on Jan. 8, 1942 — 300 years to the day after the death of the astronomer Galileo Galilei. He attended University College, Oxford, where he studied physics, despite his father's urging to focus on medicine. Hawking went on to Cambridge to research cosmology, the study of the universe as a whole.

In early 1963, just shy of his 21st birthday, Hawking was diagnosed with motor neuron disease, more commonly known as Lou Gehrig's disease or amyotrophic lateral sclerosis (ALS). He was not expected to live more than two years. Completing his doctorate did not appear likely. Yet, Hawking defied the odds, not only attaining his Ph.D. but also forging new roads into the understanding of the universe in the decades since.

As the disease spread, Hawking became less mobile and began using a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy caused his total loss of speech. A speech-generating device constructed at Cambridge, combined with a software program, served as his electronic voice, allowing Hawking to select his words by moving the muscles in his cheek.

Just before his diagnosis, Hawking met Jane Wilde, and the two were married in 1965. The couple had three children before separating. Hawking remarried in 1995 but divorced in 2006.

Hawking continued at Cambridge after his graduation, serving as a research fellow and later as a professional fellow. In 1974, he was inducted into the Royal Society, a worldwide fellowship of scientists. In 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world (the second holder was Sir Isaac Newton, also a member of the Royal Society).

Over the course of his career, Hawking studied the basic laws governing the universe. He proposed that, since the universe boasts a beginning — the Big Bang — it likely will have an ending. Working with fellow cosmologist Roger Penrose, he demonstrated that Albert Einstein's Theory of General Relativity suggests that space and time began at the birth of the universe and ends within black holes, which implies that Einstein's theory and quantum theory must be united.

Using the two theories together, Hawking also determined that black holes are not totally dark but instead emit radiation. He predicted that, following the Big Bang, black holes as tiny as protons were created, governed by both general relativity and quantum mechanics.

The main functions of the heart are:

• Pumping oxygenated blood to the other body parts.
• Pumping hormones and other vital substances to different parts of the body.
• Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
• Maintaining blood pressure

The rain change into hailstones .Kencho field were completely destroyed

With rain,heavy winds with high velocity were accompanied and it all started to rain hailstones,Lencho noticed that his field was totally white and he in misery said that a average locust would have left more grain than this.

The field was totally distroyed by heavy rain and flow of wind. As well as sum more problems created by insects also.

The rain drops changed into large hail stones. Lencho's fields was totally destroyed, the flowers were gone from the plants

Rain changed in hailstones .Lenchos field was covered by hailstones but it looked like salt was covered.

It should be technologically accessible, economically feasible and culturally acceptable. Only then, it can be termed as a ‘Resource’. Examples: minerals, forests, fossil fuels etc. Classification of Resources: (a) On the basis of origin: Biotic and Abiotic. (b) On the basis of exhaustibility: Renewable and Non-renewable. (c) On the basis of ownership: Individual (Personal), Community, National and International. (d) On the basis of status and development: Potential, Developed, Reserve and Stock. Biotic Resources are obtained from the biosphere. They have life or are living resources, e.g., human beings, fisheries, forests, etc. Abiotic Resources include all non-living things, e.g., rocks and minerals. Renewable Resources: The resources which can be renewed or reproduced by physical, chemical and mechanical processes are known as renewable or replenishable resources, e.g., water, wildlife, forests, solar energy, wind energy, etc. Non-renewable Resources: The resources which once get exhausted, cannot be remade. They take a long geological period of time, i.e., millions of years in their formation, e.g., minerals, fossil’ fuels, etc. Individual resources: Owned by individuals, e.g., own land, house; Community Owned Resources: Resources which are accessible to all the members of the community, e.g., parks, playground; National Resources: Resources which belong to the nation, e.g., roads, railways; and International resources: Resources which no individual country can utilize, e.g., oceanic waters beyond 200 km. Potential resources: Resources found in a region but not in use, e.g., solar energy in Rajasthan, wind in Gujarat; Stock: Resources available but do not have appropriate technology to access, e.g., lack of technical know how to use hydrogen and oxygen as source of energy; and Reserve: Subset of stock. Can be used for future needs, e.g., water in the dams, forest resources. Sustainable development: Sustainable economic development means that ‘development should take place without damaging the environment and development in the present should not compromise with the needs of future generation’. Land under important relief features in India: Plains-43%, Mountains-30%, Plateaus-27% Land Degradation: Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it. Measures to solve problem of land degradation: Afforestation, proper management of grazing to control overgrazing planting of shelter belts of plants, stabilization of sand dunes by growing thorny bushes, control of mining activities, avoid over-irrigation and overuse of fertilizers and pesticides; Soil erosion: The denudation of the soil cover and subsequent washing down is soil erosion. Reasons for soil erosion include— (a) Human activities like deforestation, over grazing construction, mining defective method of fanning etc.; (b) Natural forces like wind, glacier and water flow. Types of erosion: (a) Gully erosion. The running water cuts through the clayey soils and makes deep channels known as gullies. This makes the land bad land and in the Chambal basin such land is known as ravines; (b) Sheet erosion. When top soil over large area is washed away it is known as sheet erosion. Methods to prevent soil erosion in hilly area: Ploughing along the contour lines-contour ploughing; terrace cultivation; strip farming and shelter belts. Soils and its types: Alluvial soils: Entire northern plains are made of alluvial soil. Also found in the eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers. Fertile soil therefore, fit for agriculture purpose. Regions of alluvial soils are intensively cultivated and densely populated. Rich in potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. Black soil: Black in colour and are also known as regur soils. Ideal for growing cotton and is also known as black cotton soil. Found in the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh also along the Godavari and the Krishna valleys. Made up of extremely fine, i.e., clayey material. Well-known for their capacity to hold moisture. Rich in calcium carbonate, magnesium, potash and lime. Red and yellow soils: Found in the areas of low rainfall in the eastern and southern parts of the Deccan plateau. Also found in parts of Odisha, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats. Develop a reddish colour due to diffusion of iron in crystalline and metamorphic rocks. Laterite soils: Develops in areas with high temperature and heavy rainfall. Found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh, and the hilly areas of Odisha and Assam. Suitable for cultivation with adequate doses of manures and fertilizers. Low Humus content because decomposers, like bacteria, get destroyed due to high temperature. Arid soils: Found in the western parts of Rajasthan. After proper irrigation these soils become cultivable. Lacks humus and moisture because dry climate, high temperature make evaporation faster. Salt content is very high and common salt is obtained by evaporating the water. Forest soils: Found in the hilly and mountainous areas where sufficient rain forests are available. Feature differs based on location. Loamy and silty in valley sides and coarse grained in the upper slopes. Sil in the lower parts of the valleys particularly on the river terraces and alluvial fans are fertile.

The principles of effective communication are-

1. Principle of Simplicity: The message prepared for communication should be simple and easy to understand. Common words and simple sentences should be used.

2. Principle of Clarity: The message prepared for communication should be clear. An ambiguous message will not be able to make effective communication.

3. Principle of Brevity: The message should be concise in nature. The reader may feel disturbed in receiving a long message. So, only necessary information's should be given in the message.

4. Principle of Planing: Before preparing any message the communicator should plan for the message and after that, he should plan for selecting media and process of sending the message to the communicatee.

5. Principle of Accuracy: The facts and information provided in the message should be accurate. Any wrong information in the message may create confusions. As a result, communication failure may occur.

6. Principle of Attentiveness: Effective listening is important in effective communication. So, the receiver should be attentive while receiving any message.

7. Principle of relevancy: The subject matter of communication should contains relevant information. Irrelevant and unnecessary things should be eliminated from the subject matter of communication.

8. Principle of Feedback: Sending of message is not whole thing for effective communication. To be effective a feedback from the receiver is essential.

9. Principle of Time Consideration: The communicator should consider the proper time for effective communication. If communication is not made in time, Its effectiveness is lost.

10. Principle of Language Control: Control of language is important for effective communication. The communicator should be careful in selecting words and forming sentences.
