Carbonisation is the slow process of conversion of dead vegetation into coal. Scientists believe that about 300 million years ago, dead vegetation was overrun by soil. As more soil got deposited over the it, more pressure was exerted on this humus. Humus, at this stage, is called peat, the inferior quality of coal. As this went deeper and deeper (due to the weight from above), the peat began to experience more and more pressure from above and higher temperature from under. This compressed the peat and better varieties of coal were produced i.e. lignite and bituminous to anthracite (best) coal.

Animal husbandry refers to livestock raising and selective breeding. It is the management and care of animals in which the genetic qualities and behavior of animals are further developed for profit. A large number of farmers depend upon animal husbandry for their livelihood.
Animals provide us with a variety of food products which have high nutritional values. Therefore, they require a lot of care and attention.
Animals are bred commercially in order to meet the high demand for food. Dairy products from animals like cows, buffaloes, goats, are rich sources of protein. These animals are called milch animals as they provide us with milk.

Prokaryotic cells are cells without a nucleus. Eukaryotic cells are cells that contain a nucleus. Eukaryotic cells have other organelles besides the nucleus. The only organelles in a prokaryotic cell are ribosomes. Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

When the image is formed on our "Retina", the light sensitive cells of our Retina gets activated and they generate electric signals. These signals are send to brain by the optic nerves. The brain interprets the electric signals in such a way that we see an image in erect and of the same size as the object.

Cells constitute various components of plants and animals. A cell is the smallest unit of life and is capable of all living functions. Cells are the building blocks of life. This is the reason why cells are referred to as ‘the basic structural and functional unit of life’. All cells vary in their shapes, sizes, and activities they perform. In fact, the shape and size of the cell is related to the specific function it performs.

Rust is a form of iron oxide. It occurs when iron combines with the oxygen in the air causing it to corrode. Rust can affect iron and its alloys, including steel. The main catalyst for rust to occur is water. Although iron and steel structures seem solid to the eye, water molecules are able to penetrate microscopic gaps in the metal. This starts the process of corrosion. If salt is present, for example in seawater, the corrosion will be more rapid. Exposure to sulfur dioxide and carbon dioxide will also hasten the corrosive process.
Rust causes the metal to expand, which can place great stress on the structure as a whole. At the same time, the metal will be weakened and become brittle and flaky. Rust is permeable to air and water, so the metal beneath the rust layer will continue to corrode.
How to Prevent Rust?
Exposure to outdoor conditions will increase the risk of rust, especially if the climate is rainy or humid. The best ways to prevent rust include:
Using rust resistant alloys
Design considerations
Galvanization
Bluing
Organic coating
Powder coating
Regular maintenance
Using Rust Resistant Alloys
The most popular rust resistant alloys are stainless steel and weathering steel.
Stainless steel contains a minimum of 11% chromium. This allows the formation of a protective film of chromium oxide which acts as a shield against rust. The protective film will re-form if damaged. Corrosion resistance can be further enhanced with the addition of nickel.
Weathering steel, also known as “COR-TEN” steel, contains up to 21% of alloying elements such as chromium, copper, nickel and phosphorous. The alloys form a protective rust patina which reduces the corrosion rate with time. COR TEN steel tends to be cheaper than stainless steel.

A temporary arm like projections of eukaryotic cell membrane is called pseudopodia. It is temporarily filled in the cytoplasm organelle of the cell. Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments.

Crumbs are large pieces of aggregated soil present as lumps. They need to be crushed and grounded to make the soil even. This is done while ploughing and tilling of land before land is prepared for sowing. This is done with the help of iron leveller or wooden plank in smaller areas or power tillers in large areas.

Reforestation is the process of regenerating or replanting forest areas that have been destroyed or damaged for the benefits of mankind. Reforestation and afforestation share the same meaning i.e. afforestation is another name given to reforestation. Occasionally forests have the capability to regenerate due to the trees in the surroundings or due to the dispersion of seeds. However, forest lands that are badly degraded cannot be regenerated unless plants have been planted by using native methods.
