A pressure group is an organisation which attempts to influence government policies through protests and demonstrations. Pressure groups are formed when people with similar opinions get together for similar objectives. 

Examples of pressure groups are FEDECOR and BAMCEF.

The major difference between pressure groups and political parties is that unlike political parties, pressure groups do not aim to directly control or share political power.

Organisations that undertake activities to promote the interests of specific social sections such as workers, employees, teachers, and lawyers are called sectional interest groups.

From the example of Mewat, we can infer that movements take up issues which have been ignored by political parties. Political parties may then be influenced by these demands when they frame their own manifestoes. Finally, the party which comes to power ends up implementing steps which fulfil these demands.

The six-year long Assam movement (1979-1985), led by the All Assam Students Union (AASU), was aimed against the infiltration of foreigners from Bangladesh into Assam. At the end of this movement, the State Assembly was dissolved, the government was dismissed, and fresh elections were held. The Asom Gana Parishad, formed out of the AASU, contested and won the elections, forming the Government of Assam. In this example, we see a political party being formed out of a pressure group, which then goes on to form the government.

False. 

Correct : The denominator in a Representative Fraction expresses the actual distance between two places on the ground.

False. 

Correct : A linear consists of a straight line which is divided into lengths.

Verbal scale is stated in words. True.

False. 

Correct : The Distance along a curved line is measured by a divider.

1. Representative Fraction 

The Right option is :

2. Ruler 

3. Both of these

A scale is the ratio of the distance between two places on the map to the actual distance between the same two places on the ground.

This consists of a straight line which is divided into lengths that represent given distances on the earth’s surface. It is usually drawn near the lower portion of the map.

The rivers are curved. To measure length of rivers we use either the divider method or the twine methods.

The three ways used to represent the scale of a map are : 

(a) Verbal or statement scale — The scale is stated in words. The units are usually mentioned in this type of scale, for example, 1 cm = 10 km or 1 cm to 10 km. It means that 1 cm on the map is equal to 10 km on the ground. 

(b) Graphical or linear scale — This consists of a straight line which is divided into lengths that represent given distances on the earth’s surface. 

(c) Representative fraction (RF) — This is a fraction in which the numerator expresses the distance on the map and the denominator represents the actual distance on the ground. It must be noted that the numerator is always 1 and both the numerator and the denominator are expressed in the same unit.

The distance on a curved line is measured using a piece of twine or a divider. In divider method, a divider whose pointed ends are 1 or 2 cm apart is used. Beginning at one end of the feature to be measured, the divider is turned continuously till the other end is reached. The number of turns are counted and then using the scale of the map, the actual distance on the ground calculated. In the twine method, a twine is placed along the feature to be measured from one end to other. The length of the twine is then measured in cm or inches using a ruler or linear scale and then converted into km or miles using the scale of the given map.

The map scale can be represented as : 

(a) Verbal or statement scale — The scale is stated in words. The units are usually mentioned in this type of scale, for example, 1 cm= 10 km or 1 cm to 10 km. It means that 1 cm on the map is equal to 10 km on the ground. 

(b) Graphical or linear scale — This consists of a straight line which is divided into lengths that represent given distances on the earth’s surface.

Unlike political parties, pressure groups do not aim to directly control or share political power.

The two cities in the space of an inch will be found on a map where the scale is used. e.g. 1 cm on map =100 km on ground. Scales are important as without scales distance between places can’t be judged.

Pressure groups are organisation that attempt to influence government policies.

(a) Wangari Maathai

Sometimes people from an organisation and undertake activities to promote their interests or their view points. These are called interest groups. 

The movement led by FEDECOR was supported by the socialist party.

King Gyanendra dissolved the popularly elected parliament in February 2005, in Nepal.

FEDECOR organisation was compensed of local professionals, including engineers and environmentalists.

(d) Organisation.

Spleen, lymph nodes tonsils peyer's patches of small intestine,(vermiform) appendix. (any two) They act as sites for interaction of lymphocytes with the antigen and cause immune response.

Function : spleen - Trap blood -borne microorganisms & worm out RBCs thus filters blood.

Lymph nodes: Trap the microrganisms/antigens (which happen to get in to the lymph and tissue fluid).the trapped antigens activate lymphocytes &cause immune respons.

Correct option is  B) 10√2

A public company is defined as a company that offers a part of its ownership in the form of shares, debentures, bonds, securities to the general public through stock market.

Correct option is  A) 51 cm²

Correct option is (B) 3 : 1

Required ratio \(=\frac{\text{Volume of cylinder}}{\text{Volume of cone}}\)

\(=\frac{\pi r^2h}{\frac13\pi r^2h}=\frac31\) = 3 : 1

Correct option is  B) 3 : 1

As defined by the Section 3 (1) (iii) of Companies Act 1956, private limited company is ; defined by the following characteristics: 

• It restricts the right to transfer its shares. 

• There must be at least two and a maximum of 50 members (excluding current and former employees) to form a private company.

Correct option is (B) 65 cm²

Area of rhombus \(=\frac{d_1d_2}2\)

\(=\frac{10\times13}2=65\,cm^2\)

As per the Section 617 of Company Act of 1956, a Government Company means any company in which not less than 51% of the paid up share capital is held by the Central Government, or by any State Government or Governments, or partly the Central Government and partly by one or more State Governments and includes a company which is a subsidiary of a Government Company as thus defined.

Correct option is  A) PQ × SM

Correct option is  D) 28 cm²

B) Square only

Environmental factors like temperature, water, light, soil, etc., may influence the members of communities in varying degrees. Organisms in response to these factors try to adapt according to their capacities, by maintaining a constant internal environment through homeostasis or migration to a less stressful environment or suspending activities till favourable conditions return.

Besides acting as ‘conduits’ for energy transfer across trophic levels, predators are used in biological control of plant pests. This ability of the predator is based on its regulating the prey population. The natural predators reduce interspecific competition and do not harm the crop plants. 

For example, in an area the invasive cactus can be brought under control by cactus-feeding predator (a moth). Using natural predation, the ecosystem is kept stable without harming any of the trophic levels.

निम्नलिखित कारक अभिक्रिया के वेग को प्रभावित करते हैं – 

a. सान्द्रण (Concentration) – गतिज आण्विक सिद्धान्त के अनुसार आण्विक अभिक्रियाएँ अणुओं के परस्पर टकराने से होती हैं। अभिकारक का सान्द्रण बढ़ने से अणुओं की संख्या में वृद्धि होती है जिसके फलस्वरूप इकाई समय में अणुओं के आपस में टकराने की सम्भावना बढ़ने से अभिक्रिया का वेग भी बढ़ जाता है। 

b. ताप (Temperature) – ताप की वृद्धि से सक्रिय अणुओं तथा प्रभावकारी टक्करों की संख्या में, वृद्धि हो जाती है जिससे अभिक्रिया का वेग बढ़ जाता है। 

c. दाब (Pressure) – दाब बढ़ने से गैसीय अणु निकट आ जाते हैं जिसके फलस्वरूप उनके परस्पर टकराने की सम्भावना बढ़ जाती है अर्थात् वेग बढ़ जाता है। 

d. अभिकारकों के पृष्ठ क्षेत्रफल का प्रभाव (Effect of surface area of reactants) – अभिकारक पदार्थों की भौतिक अवस्था का प्रभाव विषमांग अभिक्रिया पर पड़ता है जैसे- लकड़ी के लट्टे की तुलना में लकड़ी का बुरादा तीव्रता से जलता है। अम्लों के साथ धातुओं की तुलना में धातु चूर्ण अधिक तीव्र वेग से क्रिया करते हैं अर्थात् पृष्ठ क्षेत्रफल बढ़ने पर अभिक्रिया का वेग बढ़ता है।

1. उत्प्रेरक का प्रभाव (Effect of catalyst) – उत्प्रेरक वे पदार्थ हैं, जो रासायनिक अभिक्रिया की गति को प्रभावित करते हैं। इसकी उपस्थिति में अभिक्रिया का वेग अधिक या कम हो जाता है जो उत्प्रेरक की प्रकृति पर निर्भर करता है। 

2. अभिकारकों की प्रकृति पर (On the nature of reactants) – यदि अभिकारक आयनिक है तो उस अभिक्रिया का वेग अनायनिक अभिक्रियाओं के वेग से अधिक होता है।
