Question Discussion & Solution

The correct answer is Goat>Cow>Buffalo>Sheep>Camel.

Key Points

• Livestock population in Rajasthan -
   

Explanation:

• Evolutionary biology: It is a field of science that deals with the study of evolutionary processes like natural selection, speciation & common descent that has led to the diversification of life on earth.
• Charles Darwin is known as the father of ''Evolutionary Biology''.
• 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.
• Charles Darwin wrote a book named ''The origin of species'' which is considered to be the foundation of evolutionary biology.

Additional Information 

• Herbert Spencer- He Was best known for the introduction and application of evolutionary theory to philosophy, psychology, and social sciences
• The famous phrase 'Survival of the fittest' to mean Natural Selection was coined by Herbert Spencer. He originated this phrase after the publication of famous biologist Charles Darwin’s book ‘Origin of Species’ which talked about ‘Natural Selection’.
• Julian Huxley was an English biologist, philosopher, educator, and author who greatly influenced the modern development of embryology, systematics, and studies of behaviour and evolution.
• Stanley Miller along with H.C. Urey provided experimental evidence of ''chemical evolution''

The correct answer is Local Area Network.

• A Local Area Network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home.
• A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users.
• A LAN single defining characteristic is that it connects devices that are in a single, limited area.

Additional Information

• In contrast, a Wide Area Network (WAN) or Metropolitan Area Network (MAN) covers a larger geographical area.
• Some WANs and MANs connect many LANs together.
• Ethernet and Wi-fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token ring, and Appletalk.

The correct answer is about 70% water.

Important Points

• The Top Four Elements Found in the Human Body: oxygen (65%), carbon (18.5%), hydrogen (9.5%), nitrogen (3.2%).
• The other trace elements (less than 0.01%) are boron (B), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), silicon (Si), tin (Sn), vanadium (V), and zinc (Zn).
• The six major nutrients are carbohydrates (CHO), lipids (fats), proteins, vitamins, minerals, water.
• The functions of water in the human body:
  • Water carries nutrients and oxygen to all cells in the body.
  • Water is required for breathing.
  • Water regulates your body temperature.
  • Water protects and cushions vital organs.
  • Water cushions joints.
  • Water removes waste.

Key Points

• Calcium (Ca) is the most abundant mineral in the body and is essential for a number of vital functions.
  • Also helps muscles relax and contract, important in nerve functioning, blood clotting, blood pressure regulation, immune system health.
• Iron (Fe), Part of a molecule (haemoglobin) found in red blood cells that carries oxygen in the body, needed for energy metabolism.
• Iodine found in thyroid hormone, which helps regulate growth, development, and metabolism.
• Chromium works closely with insulin to regulate blood sugar (glucose) levels.

The correct answer is All of the Above.

 Key Points

• Decision making structures require that the programmer specifies one or more conditions to be evaluated or tested by the program.
• It also involves a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.
• C programming language provides the following types of decision-making statements.
• if...else statement
  • An if statement can be followed by an optional else statement, which executes when the Boolean expression is false.
• switch statement
  • A switch statement allows a variable to be tested for equality against a list of values.
• C goto
  • The goto statement in C/C++ also referred to as the unconditional jump statement can be used to jump from one point to another within a function.

 Additional Information

• C break:
  • This loop control statement is used to terminate the loop.
  • As soon as the break statement is encountered from within a loop, the loop iterations stop there, and control returns from the loop immediately to the first statement after the loop.
