The Poona Pact refers to an agreement between Mahatma Gandhi and Babasaheb Ambedkar on behalf of depressed classes and upper caste Hindu leaders on the reservation of electoral seats for the depressed classes in the legislature of British India government. ... They finally agreed upon 147 electoral seats. The Poona Pact is significant in that it initiated a pattern of political compromise between “caste” Hindus and the Depressed Classes in the allocation of legislative representation and government jobs. The pact made the entire country morally responsible for the uplift of the depressed classes. As the concessions agreed to in the Poona Pact were precursors to the world's largest affirmative programme (reservation in legislature, public services and educational institutions) launched much later in independent India. Babasaheb Ambedkar and Mahatma Gandhi was signed 84 years ago on September 24, 1932. The agreement was signed by Pt Madan Mohan Malviya and Dr. B. R. Ambedkar and some Dalit leaders at Yerwada Central Jail in Pune, to break Mahathma Gandhi's fast unto death.

Six single bonds between Carbons and Hydrogens, three single bonds between six Carbons and Hydrogens ( alternatively) . Three double bonds present between carbons ( alternatively in hexagonal ring). So a total of nine single bonds, three double bonds are present in benzene ring.

Frédéric Sorrieu, a French artist, brought out a series of four prints in 1848. These prints depicted his dream of a world made up of ‘democratic and social Republics’. The first of the four prints, depicts all the different people of Europe and America, irrespective of age, *** or class, marching and saluting to the statue of Liberty as they pass by it. The Statue of Liberty bears a torch symbolizing Enlightenment in one hand and the Charter of the Rights of Man in the other. While on the earth in the front of the statue lie the shattered remains of the symbols of absolutist institutions like crown, sceptre; in the background the depictions of religious images and symbols guarantee divine approval. The word 'Fraternity' proclaiming Universal Brotherhood is written in the background. Sorrieu's Utopian vision had the peoples of the world grouped as distinct
nations, identified through their flags and national costume. This represents the different people of the world grouped under their own nations with symbols of their nationalism like flag and national costume.

The small intestine is where most chemical digestion occurs. After the stomach empties the food and juice mixture into the small intestine, the juices of two other digestive organs mix with the food to continue the process of digestion. One of these organs is the pancreas. It produces a juice that contains a wide array of enzymes to break down the carbohydrate, fat, and protein in food. Other enzymes that are active in the process come from glands in the wall of the intestine or even a part of that wall.

The liver produces yet another digestive juice—bile. The bile is stored between meals in the gallbladder. At mealtime, it is squeezed out of the gallbladder into the bile ducts to reach the intestine and mix with the fat in our food. The bile acids dissolve the fat into the watery contents of the intestine, much like detergents that dissolve grease from a frying pan. After the fat is dissolved, it is digested by enzymes from the pancreas and the lining of the intestine.Digested food broken down in the small intestine is the size of molecules and can now pass through the villi into the blood stream through the process of diffusion.

Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change. As already noted, this part of the process varies with different types of nutrients. Finally, all of the digested nutrients are absorbed through the intestinal walls. The waste products of this process include undigested parts of the food, known as fiber, and older cells that have been shed from the mucosa.

Bending of light at the boundary of two medium is called refraction.
The light bending ability of that particular medium is called refractive index.
Refractive index is defined as ratio of sine of angle of incidence to sine of angle of refraction.
It is denoted by n or μ.
Thus, refractive index is given by,

Absolute refractive index: When the light is going from vacuum to another medium, then the value of refractive index is called the absolute refractive index.
Relative refractive index: When the light goes from one medium ( other than vacuum or air) to another medium then that refractive index is called relative refractive index.

Unity is identified in three ways: compositional unity, conceptual unity, and gestalt unity. Variety is an opposing principle that supports and contrasts with unity by introducing dissimilar elements and ideas. Unity is a measure of how well each element of your design works together. It describes the overall design, and whether it's components work together in harmony to communicate a single idea. Unity is the most important Principle of Design because it brings your design together as one cohesive unit. 

The development does not mean the same for everyone. The goals can be different for different people. For one development can be progressing while for the other it can be destructing. Clearing of forests or destruction of old houses for making new malls  and plaza are few examples.

Voltmeter is used to measure potential difference.It is always connected in parallel across the points where the potential difference is to measured so one end of the voltmeter is connected to the point A of a resistance AB and the other end to the point B,and also it has a high resistance so that it takes a negligible current from the circuit.

Voltmeters have high resistance, so in series, they would greatly decrease the current going to the circuit.

Ammeters are very low R, so in parallel, the current would bypass the circuit, all go through the ammeter, and blow out the ammeter.

• Electric generators are based on the principle of electromagnetic induction and converts mechanical energy into electrical energy.
• An electric generator consists of a rotating rectangular coil placed between the two poles of a permanent magnet.
• The two rings R1 and R2 are internally attached to an axle. The axle may be mechanically rotated from outside to rotate the coil inside the magnetic field.
• Outer ends of the two brushes B1 and B2 are connected to the galvanometer to show the flow of current in the given external circuit.
• When the axle is rotated, arm AB moves up (and the arm CD moves down) in the magnetic field produced by the permanent magnet. Let us say that the coil ABCD is rotated clockwise. By applying Fleming’s right-hand rule, the induced currents are set up in these arms along the directions AB and CD. Thus, an induced current flows in the direction ABCD. If there are more turns in the coil, the current generated in each turn adds up to give a large current through the coil.
• After half rotation, CD and AB reverse direction, and thus, CD starts moving up and AB starts moving down. As a result, the directions of the induced currents in both the arms change. Such a current which changes direction after equal intervals of time is called an alternating current. Thus, this device is called an AC generator.
• To get a direct current, a split-ring type commutator must be used. The generator is thus called a DC generator.
• The difference between direct and alternating currents is that the direct current always flows in one direction, whereas the alternating current reverses its direction periodically.
  

Spore formation is a type of asexual reproduction found among most of the non-flowering plants and eukaryotic organisms like fungi and bacteria.
Spore formation also called as sporulation involves reproduction of new plants by producing numerous microscopic spores.
These spores are present inside the spore-producing asci which break open under favorable condition to release the spores.
Sporogenesis is usually as a result of meiotic cell division.
A typical spore of a rhizobium consists of a stalk called hyphae, spore-containing sac called sporangium, and the spores inside the sporangium.
Motile spores are called as zoospores and nonmotile spores are called aplanospores.
