Toda tribe is a Dravidian ethnic group who resides dominantly in the Blue (Nilgiri) Mountains of Tamil Nadu. Todas show co-existence with other tribal groups of Nilgiri like Kota, Badaga and Kurumba.

Famous geographer Mark Jefferson proposed the concept of the primate city in 1939. Jefferson gave the 'primate city' concept to explain the phenomenon of very large cities that hold such a large proportion of a country's population as well as its economic activity.

According to Jefferson, primate city as being "at least twice as large as the next largest city and more than twice as significant." Examples of 'primate city'are 'Tokyo' in Japan and 'Paris' in France etc.

'New Guinea' is the largest island from the given options but Greenland is the world's largest island.

Sericin is a protein created by Bombyx mori (silkworms) in the production of silk. It constitutes 25-30% of silk protein.

It envelops the fibroin fibres with successive sticky layers that help in the formation of cocoon. Sericin gives lustrous shiny appearance to silk fibre.

Blue baby syndrome (infant methemoglobinemia), is a type of illness where a baby's skin turns bluish. It begins when large amounts of nitrates in water are ingested by an infant and converted to nitrite by the digestive system.

These nitrites bind to the hemoglobin in the body, forming methemoglobin, which is unable to carry oxygen. This syndrome occurs due to a decreased amount of hemoglobin in the baby's blood.

Mitochondria, Chloroplast, Ribosomes and Lysosomes are the cell organelles present in Eukaryotic cell.

In some animals there are two insulin genes; however, in most others, including humans, a single gene is present. The insulin gene present on chromosome 11 in humans. The insulin is synthesized as 'proinsulin', which is modified to make two functional polypeptides.

Pearl is a hard-sparkling object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as a conulariid.

Pearl is composed of calcium carbonate (CaCO₃) in minute crystalline form, which has been deposited in concentric layers.

When accelerated from the rest, the energy is fully kinetic.
So, the Kinetic Energy (KE) = Charge x Potential Difference

= MV² = Q.V

• From the above equation, it is obvious that the velocity of particle is inversely proportional to the mass of that particle.
• So, electron will gain more speed as it has lower mass than proton. Also, the energy is fully kinetic in above case; hence, the electron will have greater energy as a result of greater velocity.

• As it is given in the question that electrical conductivity of wire 1 i.e. made up of copper is greater than wire 2 i.e. made up of aluminium.
• Electrical conductivity is inversely proportional to the resistance. So, the resistance of wire 2 will be higher than that of wire 1.

Angle of deviation: It is the angle made by the reflected ray and the original path of the incident ray (as shown in the diagram)

Angle of Deviation (δ)  = 180° - [ i + r ]  or  180°- 2i (as i=r) 
= 180°- [ 40° + 40°]
= 100°
Therefore, a ray of light will undergo a deviation of 100°

All the statements related to radiations/lights are correct except statement 4.

• The wavelength of infrared is more than that of ultraviolet radiation.
• The wavelength of ultraviolet is smaller than that of visible light.
• The photon energy of visible light is more than that of infrared light.
• The photon energy of ultraviolet is lesser than that of visible light.

Note:

• Order of frequency is as follows: Radio Waves< Microwaves< Infrared Radiation< Visible Light< Ultraviolet Radiation< X-rays< Gamma Rays.
• Order of wavelength is as follows: Radio Waves> Microwaves> Infrared Radiation> Visible Light> Ultraviolet Radiation> X-rays> Gamma Rays.

Whenever Power Conversion occurs in any device or machine then there is an opposition to the energy conversion which is converted to power loss or the power loss may occurs during transmission of power either in mechanical or electrical.

• In a transformer energy is converted to magnetic field and back to electrical energy, thus there exists magnetic losses i.e. hysteresis loss and Eddy current loss and electrical loss i.e. Cooper loss.
• These energy losses are dissipated in the form of heat thus generating heat in transformer.

A person is standing on a frictionless horizontal ground. He can move by a certain distance on this ground by sneezing. This is because of Newton’s ^3rd law of motion. As he sneezes, air from is nose blow out with a strong force, as a resultant of this forward flow of air, there will be an opposite reaction that will lead to backward movement of the person.

Note: Newton’s 3^rd law states that, for every action, there is an equal and opposite reaction.

Bronsted and Lowry proposed the concept of acids and bases in the year 1923.

• As per the concept, acid is defined as a substance which has the tendency to give a proton while base is defined as a substance which has a tendency to accept a proton.
• In the above reaction, water accepts proton, hence it acts as a base.

There are 12 atoms of hydrogen per molecule of glucose, which has a molecular mass of 180g/mol. Hence, the number moles of hydrogen = 12 x 1.50 = 0.10 mol. Hence, the number of hydrogen atoms is found by multiplying this by the Avogadro Constant, 6.02 x 10²³. This will give 6.02 × 10²².

• Plaster of Paris (POP), quick-setting gypsum plaster consisting of a fine white powder (calcium sulfate hemihydrate), which hardens when moistened and allowed to dry.
• It is also known as the Plaster of Paris because for the preparation of POP, the abundant gypsum found near the capital city of France i.e. Paris.
• The chemical formula of Plaster of Paris is 

• Flint glass is considered as the softer glass than any other glass.
• It is clearer and transparent. For making optical glass Potassium and lead silicates are used.
• The main use of flint glass is in the manufacturing of lenses, prisms, and other optical instruments.

Most ozone gas (about 90 %) is located in the atmospheric layer of Stratosphere.

Based on temperature variation our atmosphere can be classified into the following layers mainly;

• Troposphere – From Earth’s surface up to 10 km. Here, temperature decreases with increasing height. We, humans, live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here.
• Stratosphere – From 10 km above the surface to 50 km above the surface. Here, temperature increases with increasing height due to the presence of the ozone layer. Ozone gas is capable of absorbing harmful UV rays and due to the absorption the temperature increases. All the aeroplanes fly in this zone as due to high temperature there is less turbulence and hence smoother flights are possible.
• Mesosphere – From 50 km above the surface to 85 km above the surface. Here, the temperature again decreases with increasing height. Most meteors burn up in the mesosphere
• Ionosphere – Beyond 85 km there is thermosphere layer and Ionosphere is a series of regions in parts of the mesosphere and thermosphere.

Note: Ozone(O₃) is blue in colour and has strong odour while Oxygen(O₂) is colourless and odourless.

The major constituent of biogas are Methane and Carbon dioxide while some traces of H₂S and ammonia are also there.

• It is released when the Cow, Buffalo and Pig manure is processed Anaerobically i.e. in the absence of Oxygen.

• Biogas can be used for Space Heating, Generation of Electricity, Fuel for Cooking etc.

Note: Biogas is a Clean Renewable Energy Source and even it is Economically Friendly.

• Rajasthan and Haryana are theonly states who have made it necessary to hold certain minimum educational qualifications to be eligible to contest Panchayat Elections.
• Karnataka, Gujarat and Chhattisgarh have put a restriction of having a toilet at home to be eligible to contest Panchayat Elections.

Note: Part IX relates to the three-tier Panchayati Raj Institutions and was added to the Constitution by the 73rd Amendment in 1993.

• Delegation is the assignment of any responsibility or authority to another person to carry out specific activities. Hence 1^st statement is wrong.
• In delegation, the manager empowers a subordinate to make decisions i.e. the higher authority is conferring specific authority to a lower authority. Hence, 2^nd statement is also wrong.

The only option left i.e. option 3 is the answer.
Note: The Manager is still accountable even after the delegation.

In 2016-2017 the rate of increase in potato production was more than the onion production in comparison to 2015-2016. Hence, the 3^rd statement is not correct, and rest all are true.

Note: Horticulture is the cultivation, processing, and sale of fruits, nuts, vegetables, ornamental plants, and flowers. Many additional services are also associated with it.

Option two is correct.

• The demographic dividend is an economic benefit resulting from the increase in the working age population.
• For a demographic dividend, a country must go through a demographic transition where it switches from a largely rural agrarian economy with high fertility and mortality rates to an urban industrial society characterized by low fertility and mortality rates.
• India is currently going through the phase of the demographic dividend.

Note: The term, “demographic dividend”, was first coined by David Bloom.

The correct answer is (a) i.e. 1, 2, 3
All are related to Five-year plans of the Planning Commission

• Mahalanobis Model – Second Five-year plan. The essence of the model is a shift in the pattern of industrial investment towards building up a domestic consumption goods sector.
• Plan Holiday – After the failure of the third Five-year plan. The government declared plan holidays (from 1966–67, 1967–68, and 1968–69) and there were annual plans instead of Five-year plans.
• Rolling Plan - The Janta Government terminated the fifth Five-year plan in 1977-78 and launched its own sixth Five-year plan for period 1978-83 and called it a Rolling Plan

Note:Planning Commission is now replaced by NITI Aayog

The correct answer is1 and 2 only
