Laterite soils are found mainly in the states of Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and the hilly regions of Orissa and Assam.
In the hilly areas of Karnataka, Kerala and Tamil Nadu this soil is suitable for the growth of tea and coffee.

Red laterite soils of Tamil Nadu, Andhra Pradesh and Kerala are more suitable for crops like cashew nuts.

There is a great change in the caste system because of various factors such as:

(1) occupational mobility

(2) urbanisation

(3) breaking down of old notions of caste hierarchy

(4) increasing literacy rate

(5) breaking social order and power of landlords

For maximum number of columns, we need to find highest common factor i.e., HCF of 612 and 48.

Now, 

612 = 48 × 12 + 36

48 = 36 × 1 + 12 

36 = 12 × 3 + 0

HCF of 612 and 48 is 12. 

Maximum number of columns in which they can march is 12.

Let 5 + 2√3 be a rational number.

5 + 2√3 = \(\frac{p}{q}\), where p and q are co-prime integers.

2√3 = \(\frac{p}{q}\) - 5

= \(\frac{p - 5q}{q}\)

√3 = \(\frac{p - 5q}{2q}\)

Here, \(\frac{p - 5q}{2q}\) is rational as p and q are integers. 

But it is given that √3 is irrational.

LHS is irrational and RHS is rational.

Which contradicts our assumption that 5 + 2√3 is a rational number.

5 + 2√3 is an irrational number.

Triangular numbers are figurate numbers that can be represented by an arrangement of dots in a triangular shape.

Figurate numbers are the broader idea of any number that can be represented by dots in a geometric shape.

100th Number in the Triangular Number = 5050

(a) what she was doing in the kitchen. 

(b) she was busy helping Ramya. 

(c) what work Ramya had there. 

(d) was eating jalebis that mother had made for the guests.

(i) Cr²⁺ is reducing as its configuration changes from d⁴ to d³, a more stable half filled t_2g configuration while Mn³⁺ is oxidising as Mn³⁺ to Mn²⁺results a more stable half filled d⁵ configuration.

(ii) It is due to greater number of unpaired electrons in (n–1)d and ns orbitals at the middle of the series.

Alkyl amine is more basic than ammonia because the ^+I effect or electron donating nature of alkyl group increases electron density on ‘N’ atom in alkyl amine.

(i) Detergents: Detergents are cleansing agents which have all the properties of soaps, but actually do not contain any soap e.g., sodium dodecylbenzene sulphonate. These can be used both in soft and hard water as they give foam even in hard water. Detergents are mainly classified into three categories:

(i) Anionic detergents
(ii) Cationic detergents
(iii) Non-ionic detergents

(ii) Food Preservatives: These are the chemical substances which are added to the food materials to prevent their spoilage due to microbial growth and to retain their nutritive value for long time. Sodium benzoate, sodium metabisulphite are some common preservatives. Preservatives prevent rancidity and kill or inhibit the growth of microorganism.

(iii) Antacids: These are the chemical substances which neutralize the excess acid and raise the pH to an appropriate level in the stomach. Sodium hydrogen carbonate or a mixture of aluminium and magnesium hydroxide are some common antacids.

(i) Haloalkanes dissolve in organic solvents because the new intermolecular attractions between haloalkanes and organic solvent molecules have much the same strength as ones being broken in the separate haloalkanes and solvent molecules.
(ii) An equimolar mixture of a pair of enantiomers is called racemic mixture. For example, butan-2-ol. A racemic mixture is optically inactive due to external compensation.

(iii) Of the two bromo derivatives, C₆H₅CH(CH₃)Br and C₆H₅CH(C₆H₅)Br, the intermediate obtained from C₆H₅CH (C₆H₅) Br is more stable than obtained from C₆H₅CH(CH₃) Br because it is stabilised by two phenyl groups due to resonance. Therefore, C₆H₅CH (C₆H₅)Br is more reactive than C₆H₅(CH₃) Br.

Management of cattle farming is known as animal husbandry. It includes various tasks such as giving food to cattles, animals, shelter, breeding, health, disease control and proper economic utilization. Animal farming includes cow, buffalo, goat, sheep, camel, poultry, and fisheries. Due to increasing population, demand for milk, eggs, meat etc is also increased. Now farmers take up animal husbandry on commercial basis so it needs scientific management practices. cattle farming is done for milk and agricultural work. By poultry we increase meat an eggs production. fisheries is a cheap source of protein food.

A cell is the basic unit of life for all living organisms. Cytosol and cytoplasm are two components of a cell. Cytosol is the intracellular fluid present within the cytoplasm. Cytosol is often confused with cytoplasm but one must realise that both are different entities.

The difference between cytosol and cytoplasm-

Intensive insulin regimens attempt to mimic the body’s normal pattern of insulin secretion, and deliver replacement insulin using the concepts of basal and bolus insulin coverage.

When you are intensively managed with insulin your medical provider will prescribe an insulin regimen for you, but these are the general principles:

Your insulin regimen will include:

1. A basal or background insulin dose
2. A bolus insulin dose to cover the sugar or carbohydrate in your food
   This will be presented as an insulin to carbohydrate ratio (I:CHO). The I:CHO tells you how many grams of carbohydrate can be covered by one unit of rapid acting insulin
3. A high blood sugar correction bolus insulin dose to bring your blood sugar back into the target range. This will be presented as a correction factor. This correction factor refers to how much your blood sugar will drop after 1 unit of insulin rapid acting insulin.

With the exception of ADP, all acute porphyrias are inherited in an autosomal dominant fashion and are of low penetrance. Furthermore, VP and HCP may also present with skin lesions similar to cutaneous porphyrias.

The two types of immunity are active immunity and passive immunity. 

Active immunity: Immunity developed in the host body due to production of antibodies in response to antigens. 

Passive immunity: When ready-made antibodies are directly given to protect the body against foreign agents.

The valve between left atrium and left ventricle is known as mitral valve or bicuspid valve. It allows blood to flow from left atrium to left ventricle but not in reverse direction.

Democratic style of leadership is one in which the leader develops action plans and makes decisions in consultation with his subordinates. He encourages subordinates to participate in decision making.

Meenakshi Chemicals Ltd. will require more working capital because time gap between placement of order and delivery is very high.

Stability of Dividend.

Types of plans Sarita is discussing in the above lines are:
(a) Policy  Policy is a general guideline which brings uniformity in decision making for achievement of predetermined objectives.
(b)Procedure  It consists of sequence of routine steps on how to carry out activities. It details the exact manner in which any work is to be performed.

(i) The discussed objectives of management are: 

(a) Organisational objectives:- These are the economic objectives of a business. These are related to survival, profit and growth of business. The management must strive to ensure survival of the organisation. For this, it must earn enough revenue to cover costs. The management has to ensure that it makes a profit, because profit provides a vital incentive for continued operation of an enterprise. Further, the management must exploit the growth potential of organisation to remain in the industry. 

(b) Social objectives:- These objectives involve creation of benefits for society. For example, giving employment to the disadvantaged section of society, using environmental friendly methods of production, providing amenities to community etc. As every organisation is a part of society, these obligations have to be fulfilled. 

(ii) The two values which company wants to communicate to the society are: 

(a) Care and concern for employees and society at large:- They decided to open schools and crèches for the children of its employees. They decided to give employment to the people of nearby villages as few job opportunities were available in that area. 

(b) Environmental concern:- They are promoting the use of a non-conventional source of energy, i.e. solar energy. Solar energy is easily available everywhere and does not cause pollution. The company is conserving environment by making solar lanterns.

Level of competition affects the working capital requirement of an organisation as higher competition requires larger stocks to meet urgent orders from customers which results into requirement of more working capital.

Developing planning premises.

It is a short term unsecured, negotiable promissory note with a fixed maturity period which is issued by large and creditworthy companies to raise short term funds at lower rates of interest than the market rates.

Principles of management help managers in taking scientific decisions as they are based on objective assessment of the situation and emphasize on logic rather than blind faith.

Laissez Faire’ style of leadership is one in which the leader gives complete freedom to the subordinates and depends largely upon the group to establish its own goals and work out its own problems.

Standardisation and simplification.

Principles of management provide useful insights into reality by enabling the managers to learn from past mistakes and conserve time by solving recurring problems quickly.

The principle of management which is being violated in this case is Unity of Command. Consequence will be that salesman will be confused regarding whose instructions should he follow. Therefore, it may be difficult to carry out the order of two persons when they are contradictory.
