Political theory deals with the ideas and principles that shape Constitutions, governments and social life in a systematic manner. It clarifies the meaning of concepts such as freedom, equality, justice, democracy, secularism and so on. It probes the significance of principles such as rule of law, separation of powers, judicial review, etc. This is done by examining the arguments advanced by different thinkers in defense of these concepts. Though Rousseau or Marx or Gandhi did not become politicians, their ideas influenced generations of politicians everywhere. There are also contemporary thinkers who draw upon them to defend freedom or democracy in our own time. Besides examining arguments, political theorists also reflect upon our current political experiences and point out trends and possibilities for the future.

The political theory deals with the ideas and principles that shape constitutions, governments and social life.

We study certain values and principles and ideals also which inspired people and guided policies like democracy, freedom, equality, etc.

Politics:

• Politics may have different ideas to be argued upon.
• Politics is associated with the satisfaction of wants.
• Politics is sometimes considered to be what politicians do. But it associates them with teams due to their false commitments, etc.
• Politics promotes the interests of an individual by all means.

Political Science:

• It is a scientific study of political ideas and principles.
• Political Science shapes the government and public opinion in a well-mannered way.
• Political science examines the defections, false commitment and false promises made by politicians.
• Political Science examines the validity of concepts of equality, justice, freedom, democracy, secularism, etc.
• The philosophers in political science can generate the new ideas to mould the society.

Explanation: The Earth's axis is an imaginary line joining the North Pole and the South Pole. This axis is tilted at an angle of 23½° with respect to the plane of the Earth's orbit. This tilt is also known as the inclination of the Earth's axis.

HRD Minister Ramesh Nishank announced a major CBSE syllabus reduction for the new academic year 2020-21 on July 7 which was soon followed by an official notification by CBSE on the same.

Considering the loss of classroom teaching time due to the Covid-19 pandemic and lockdown, CBSE reduced the syllabus of classes 9 to 12 with the help of suggestions from NCERT.

The CBSE syllabus has been rationalized keeping intact the learning outcomes so that the core concepts of students can be retained.

1. Apply the question to yourself

This is the best way to solve blood relation questions. Here you try and relate every statement to yourself. The starting name of the statement could be assumed as your name or you

<a name="more"></a>
 

2. Break the question into very small parts

When the statement is very long, it can get confusing. So break down every statement in the question into sub statements and solve the question.
 

3. Do not assume the gender

Do not assume the gender of any person in the question just based on the names given in the question.
 

4. Draw clear diagrams as you solve

An easy trick to solve such questions with 100% accuracy is to draw a family try where people of the same generation are placed at the same level and the entire diagram is in the form of a hierarchy.

Explanation:

A point has only one property, its location. It is a mathematical abstraction, with no length, width, or height, no thickness or volume. We say that a point has zero dimensions, even though it might take one or more numbers to specify the location of the point.

Process of Translation

The protein synthesis occurs in two steps, namely transcription and translation. During transcription, the information from DNA is encoded into mRNA. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins. 

Transcription takes place in the nucleus. During transcription, DNA partially unwinds by the enzyme helicase. This results in the single nucleotide chain to be copied. RNA polymerase reads the DNA strand from the 3' to 5' direction and synthesizes the complementary strand of messenger RNA in the 5' to 3' direction. The DNA strand which is transcribed is called as the template strand. The nucleotides on the RNA strand are complementary to the nucleotides on the DNA strand. DNA cytosine pairs with RNA guanine, DNA guanine pairs with RNA cytosine, DNA thymine pairs with RNA adenine and DNA adenine pairs with RNA uracil. After mRNA is synthesized, it is transported to the cytoplasm where it binds with ribosomes. Ribosomes are the sites of protein synthesis. Ribosomes have three important binding sites, one for mRNA and two (A site and P site) for tRNA. The start codon methionine occupies the P site and the second codon occupies the A site. The tRNA molecule whose anticodon is complementary to the mRNA forms a base pair with the mRNA in the A site. A peptide bond is formed between the amino acid attached to the tRNA in the A site and the methionine in the P site. The ribosome then slides down the mRNA in such a way that the tRNA in the A site moves to the P site and a new codon occupies the A site. This process continues until one of the three stop codons occupies the A site. At that point, the protein chain connected to the tRNA in the P site is released and the translation is complete.

Transcription

Transcription is the process of synthesis of RNA from DNA template. A segment of DNA gets copied into mRNA during the process. The process of transcription starts at the promoter region of the template DNA and terminates at the terminator region. The segment of DNA between these two regions is known as transcription unit. The transcription requires RNA polymerase enzyme, a DNA template, four types of ribonucleotides, and certain cofactors such as Mg2+.

The three important events that occur during the process of transcription are as follows.

(i) Initiation

(ii) Elongation

(iii) Termination

The DNA-dependent RNA polymerase and certain initiation factors (σ) bind at the double stranded DNA at the promoter region of the template strand and initiate the process of transcription. RNA polymerase moves along the DNA and leads to the unwinding of DNA duplex into two separate strands. Then, one of the strands, called sense strand, acts as template for mRNA synthesis. The enzyme, RNA polymerase, utilizes nucleoside triphosphates (dNTPs) as raw material and polymerizes them to form mRNA according to the complementary bases present on the template DNA. This process of opening of helix and elongation of polynucleotide chain continues until the enzyme reaches the terminator region. As RNA polymerase reaches the terminator region, the newly synthesized mRNA transcripted along with enzyme is released. Another factor called terminator factor (ρ) is required for the termination of the transcription.

The earth is called a unique planet because:

1. It is the only planet which has favorable conditions that support life. It is neither too hot nor too cold.
2. It has water and air, which are very essential for our survival.
3. The air has life-supporting gases like oxygen.

• • The writer contrasts Chinese art with European art by using two stories.
  • The Tang Emperor Xuanzong commissioned the painter Wu Daozi to decorate a palace wall, When it was done the Emperor admired the scene.
  • The painter drew the Emperor’s attention to a cave and when he clapped his hands the entrance of the cave opened.
  • The painter entered but before Emperor could move the entrance closed and the painting vanished, along with the artist.
  • In another story, a painter wouldn’t draw the eye of a dragon he had painted for fear it would fly out of the painting.
  • The writerthen cites a story representative of Western painting in which a master blacksmith Quinten Metsysfell in love with a painter’s daughter.
  • To be accepted as a son—in—law Quinten painted a fly on the painter’s latest panel When the painter tried to swat it away he realised the truth — Quinten wastaken on as an apprentice and married his beloved.
  • These stories reveal what each form tries to achieve.

• The Europeans want a perfect illusionisticlikeness while in Asia It is the essence of inner life and spirit. In the Chinese story only the artist knows the way within and he reaches his goal beyond material appearance.
• Unlike a Western figurative painting a classical Chinese landscape does not reproduce an actual view and one can enter it from any point and travel in it.
• It requires the active participation of the viewer both physically and mentally.
• Man becomes a means of expression of communicatIon or ‘the eye of the landscape’.

Let the duration be x

Let Train A be the train that traveled at 30km/h

And Train B be the train that traveled 35 km/h

Express the distance traveled by train A in term of x

Distance = Speed x Time

Distance = 30x

Express the distance traveled by train B in term of x

Distance = Speed x Time

Distance = 35x
 

The length of the each train is 200 m.

Therefore, for the train to completely cross each other, Train B (the faster train) will have to be 200 ahead of train A.

Convert 200 m to km

200m = 0.2 km

solve x:

35x - 30x = 0.2 km

5x = 0.2

x = 0.04 h or 2.4 mins

Answer: The train will crossed each other in 2.4 mins.
