a) The displacement reaction which is. highly exothermic and the metal produced is in molten state is called thermite reaction.
i) Since the oxide of the metal is Q₂Q₃ its valence is 3. therefore out of the mentioned metal only aluminium and iron can be the metal with properties mentioned above.
ii) QCl₂ and QCl₂ must be iron as it shows variable valency of two and three. FeCl₂ and FeCl₃ are the chlorides.

The statement is True.

c) 0217, an octal integer precedes

Symbols used to perform an operation is called Operator.

1. Character set: 

To study a language first we have to familiarize the character set. For example, to study English language first we have to study the alphabets. Similarly here the character set includes letters(A to Z & a to z), digits(0 to 9), special characters(+, -, ?, *, /, …..) white spaces(non printable), etc.

2. Token: It is the smallest individual units similar to a word in English or Malayalam language. C++ has 5 tokens 

• Keywords: These are reserved words for the compiler. We can’t use for any other purposes. 

Eg: float is used to declare variable to store numbers with decimal point. We can’t use this for any other purpose

• Identifier: These are user defined words. 

Eg: variable name, function name, class name, object name, etc… 

• Literals (Constants): Its value does not change during execution 

eg: In maths % = 3.14157 and boiling point of water is 100. 

• Punctuators: In English or Malayalam language punctuation mark are used to increase the readability but here it is used to separate the tokens. 

eg:{,}, (,), …….. 

• Operators: These are symbols used to perform an operation(Arithmetic, relational, logical, etc…).

\n is a character constant and it is also known as escape sequence. This is used to represent the non graphic symbols such as carriage return key(enter key), tab key, backspace, space bar, etc. It consists of a backslash symbol and one more characters.

#include<iostream>

using namespace std; 

int main()

{ 

cout<<” SMOKING IS INJURIOUS TO HEALTH”; 

}

i – Incisors, c-Canines, pm – Pre molars, m – Molars

a) At & T Bell Laboratory

The major portion of absorption takes palce in small intestines. In stomach simple sugars, water and alcohol absorbed. Villi are specialized projections in small intestine with large absorbent area. This facilities better absorption of complex molecules as well.

As food is fit to be absorbed only after complete digestion so villi’s turn comes after all the digestive processes are complete.

1. Bile salts 

2. Emulsification. The conversion large fat globules into tiny fat droplets is called emulsification. Bile salt helps emulsification. Emulsification increase the surface area for lipase action.

1. Secretin acts on exocrine part of pancreas. 

2. Secretin stimulates secretion of water and bicarbonate ions from pancreas. It protects the intestinal mucosa from acid as well as provide an alkaline medium for enzymatic activity in intestine.

int x; is a valid declaration.

(b) Identifier

Yes, The caloric values of carbohydrates, proteins and fats are 4.1 kcal /g, 5.65 kcal /g and 9.45 kcal /g, respectively

(d) “c”, It is a string constant the others are character constant.

sum.obj is not needed and can be deleted.

d) Alvis, the others are keywords.

age is an identifier.

b) main( ). A  C++ program must contains at least one main( ) function.

sum.exe file is a must to run the program.

c) Key words

\n escape sequence is used.

A typical website is comprised of a set of files (each web page—home page, about page, etc.—is an individual file). Each file contains HTML code and content (text and images). Web pages are styled with files called Cascading Style Sheets (CSS). For ease of explanation, let’s say that a standard (non-responsive) website has a set of files and a few CSS files that govern the look of the site. A responsive website applies an alternate set of CSS files depending on the device being used to access the site. The site looks and ‘responds’ differently based on the device. 

For example, while someone viewing the site from a desktop device sees a horizontally aligned navigation menu, someone viewing the site from a mobile device gets a vertically aligned navigation menu with larger text that is easier to read on a smaller screen.

Correct HTM code will be:

<img src="c:\desktop\one.jpg" align="center" />

In <a> tag we take href.

href specifies the URL of the page the link goes to

So the correct code will be:

<a href="c:\desktop\abc.html"> Next page <a/>

Answer is c. 18

b. Mumbai#Chennai#Kolkata#Mumbai#

Answer is d. 250 300

Answer is b. 50#5

Correct HTML Code is:

<table border="1" bgcolor=”red” style="border-color: green;">

or

<table border="1" style="border-color: green; background-color:red;">

or

<table style="border: 1px solid green; background-color:red;">

The general form of this will be:

There is no k/( k − h + 1)-competitive k-server algorithm for the (h, k)-server problem.

Origin of Species by Natural Selection:

• It was written by Charles Darwin.
• It was a groundbreaking scientific work by British naturalist Charles Darwin.
• It was originally published in 1859.
• Darwin, through his theory, argued, that organisms gradually evolve through a process he called “natural selection.”
• In natural selection, organisms with genetic variations that are better suited to their environment have an advantage over the organisms of the same species that lack the variation.
• And thus, the better-suited organism or specie, are in turn more likely to survive and more likely to give their features to future generations than the other.
• And such, the cycle of natural selection of the specie is carried out during the course of evolution.

Charles Darwin:

• Charles Darwin was born in 1809 in Shrewsbury, England.
• Darwin proposed a theory of evolution called natural selection in the year 1859.
• According to it those populations which are a better fit (reproductively fit) in an environment will be selected by nature and will survive more.
• Darwin's theory of natural selection is popularly known as 'Darwinism'.
• English naturalist Charles Darwin developed the idea of natural selection after a five-year voyage to study plants, animals, and fossils in South America and on islands in the Pacific.
• Darwin conducted a sea voyage in a sailing ship called H.M.S Beagle as a part of his experiments on the theory of evolution.
• Charles Darwin became almost universally thought of as the "Father of Evolution".
• Darwin's process of natural selection has four components:
  • Variation 
  • Inheritance
  • High rate of population growth
  • Differential survival and reproduction
• Charles Darwin died in 1882 at the age of seventy-three.

Thus, Charles Darwin wrote 'Origin of Species'.

• Misl refers to the sovereign states of the Sikh Confederacy, that rose during the 18th century in Punjab. 
• The Misls were not a consolidated power.
• It represented military brotherhood with a democratic set-up and controlled the regions of Punjab.
• The 12 Misls varied in size, power as well as importance. But they were “equal” as far as the matter of Sikhism is concerned. 
• It is cited as one of the causes of the weakening of the Mughal Empire prior to Nader Shah's invasion of India.

Ranjeet Singh:

• Lahore served as the capital of Punjab under Raja Ranjeet Singh reign.
• Raja Ranjit Singh was the chief of Sukerchakia Misls.
• He was a strong and courageous soldier, efficient administrator and skilful diplomat.
• He started his campaign against all the misls to create one single state of Punjab.
• He conquered Lahore in 1799 and Amritsar in 1802.
• He also brought all Sikh chiefs west of Sutlej under his control and later acquired Kashmir, Multan and Peshawar.
• He created a powerful army and recruited Gurkhas, Biharis, Oriyas, Pathans, Dogras along with Sikhs.
• After his death, his kingdom was torn by an internal power struggle and the British acquired Punjab in 1849.

Ranjeet Singh belonged to Sikh Misls of Sukerchakia.

The 12 Misls in Punjab: - Ahluwalia, Sukrachakia, Bhangi, Phulkia, Dalwalia, Faljulapuria, Kanhaiya, Karoda Sinhaia, Nakai Nihog, Nishanwala, Ramgarhia. 

a) An equal to (=) sign

A formula in calc always starts with An equal to (=) sign.

a. Jute

Jute has high strength. Therefore used to make sacks but due to rough texture it is unsuitable to be used for clothing.

It is Kwashiorkor

Correct option: a) An equal to (=) sign

Here we used the output operator cout<<. It is used to display a message “welcome to C++” to use this operator the corresponding header file must be included. We didn’t included the header file hence the error.

(c) Disaccharides, dipeptidase and lipases

To represent null character is used \0.
