Question Discussion & Solution

Explanation:

• Bacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms.
• On the basis of origin, bacteria can be divided into two types - Archaebacteria & Eubacteria

Archaebacteria:

• These bacteria are special since they live in some of the harshest habitats such as extreme salty areas (halophiles), hot springs (thermoacidophiles) and marshy areas (methanogens).
• Archaebacteria differ from other bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions.
• For example - Methanogens are present in the gut of several ruminant animals such as cows and buffaloes and they are responsible for the production of methane (biogas) from the dung of these animals.

Additional Information 

Eubacteria:

• There are thousands of different eubacteria or ‘true bacteria’.
• They are characterised by the presence of a rigid cell wall, and if motile, a flagellum.
• The Eubacteria can be both autotrophic & heterotrophic.

The longest Highway in the state is NH 15 of length 878.3 km and Smallest is 71B of length 5 km.

• The highway starting from the junction of NH- 71 near Rewari in the state of Haryana of 69 km and connecting Dharuhera and passing through Rajasthan of 5 km and connecting Taoru -Sohna and terminating at its junction with NH 2 near Palwal.
• NH 79 A - Kishangarh- Nashirabad - 35 km
• NH 11 C - Old alignment of NH no. 8 passing through Jaipur. Length in Rajasthan 53 km
• NH 3 - Agra-Gwalior-Shivpuri-Indore-Dhule-Nasik-Thane-Mumbai. Length in Rajasthan 32 km

The correct answer is Initialize the object.

• The constructor is a method of class or structure used in object-oriented programming that initializes a newly created object.

Key Points

• Whenever the object is created, the constructor is called automatically.
• A constructor is used to set the values for the variables.
• There are three types of constructors: default constructor, parameterized constructor, and copy constructor.
• The name of the constructor should be the same as the class name and it never returns any value so it has no return type.
• Default constructor accepts no parameter, the parameterized constructor accepts arguments and copy constructor accepts a reference of its own class as a parameter.

Hypertext transfer protocol (HTTP):

• HTTP is used to access data on the world wide web. HTTP functions as a combination of FTP and SMTP. HTTP uses the services of TCP port number 80. HTTP is a stateless protocol.
• HTTP prior to version 1.1 specified a non-persistent connection, while a persistent connection is a default.
• In a non-persistent connection, one TCP connection is made for each request/ response. The client opens a TCP connection and sends a request and server sends the response then closes the connection.

File Transfer Protocol (FTP):

• FTP stands for file transfer protocol. It is provided by TCP/IP for copying a file from one host to another. FTP can transfer a file through one of the following three modes: stream mode, block mode and compressed mode. Stream mode is the default mode.
• FTP uses two TCP connections one for data and another for control.

Simple Transfer Protocol (SMTP):

• SMTP is a push protocol, it can push the messages from the client to the server only.
• SMTP uses one TCP connection at a time

TELNET:

• TELNET is a client/ server application that allows a user to log on to a remote machine, giving the user access to the remote system.
• TELNET uses one TCP connection at a time.

Important Point:

Option 1 is not correct since HTTP might have more than one TCP connections for a single web page.

​The correct answer is Sirohi.

• The district of Rajasthan, where the tropical dry deciduous forests are not found in Sirohi.

Key Points

• Biodiversity of Rajasthan:
  • Though a large percentage of the total area is desert and even though there is little forest cover, Rajasthan has rich and varied flora and fauna.
  • The natural vegetation is classed as Northern Desert Thorn Forest (Champion 1936).
  • These occur in small clumps scattered in more or less open forms.
  • The density and size of patches increase from west to east following the increase in rainfall.
  • The Northwestern thorn scrub forests lie in a band around the Thar Desert, between the desert and the Aravallis.
  • The Aravalli and the south-eastern region is home to the dry deciduous forests, with tropical dry broadleaf forests that include teak, Acacia, and other trees. Hence Sirohi is the correct answer.
  • The hilly ‘Vagad’ region lies in southernmost Rajasthan.
  • Vagad is the wettest region in Rajasthan, and the most heavily forested.
  • North of ‘Vagad’ lies the Mewar region, home to the cities of Udaipur and Chittaurgarh.
  • All these regions have varied flora and fauna distinct to the region.
