Question Discussion & Solution

Linen, Polyester and Rayon are types of clothing fibers or fabric, while Terracotta is a clay-like earthenware ceramic.

• Vitamin is an organic non-protein substance that is required by an organism for normal metabolic function but cannot be synthesized in sufficient quantity by that organism. 
• These can be divided into two categories: fat-soluble and water-soluble.

Fat-Soluble vitamins

• Fat-soluble vitamins are soluble in fats.
• They are absorbed by fat globules that travel through the small intestines and into the general blood circulation within the body.
• Unlike water-soluble vitamins, fat-soluble vitamins are stored in the body when they are not in use.
• Vitamin A, D, E K are fat-soluble.

Water-soluble vitamins

• Water-soluble vitamins dissolve in water, which means these vitamins and nutrients dissolve quickly in the body.
• Unlike fat-soluble vitamins, water-soluble vitamins are carried to the body’s tissues, but the body cannot store them.
• Any excess amounts of water-soluble vitamins simply pass through the body
• Vitamin B and Vitamin C are water-soluble.

Key Points

Thus, the disease caused due to deficiency of Vitamin B1 is Beri Beri.

The correct answer is Tartaric acid.

• Tartaric acid is an organic acid that is white and crystalline.

Key Points

• It is found naturally in many fruits like grapes, bananas, tamarind, etc.
• This acid is added to foods as an antioxidant and to give its distinctive sour taste.
• Crystals and powders are prepared by a chemical process.
• It is also added to food for preservation.
• It is also a good antioxidant and is beneficial for kidneys.
• It helps to absorb minerals in the body.
• It is also helpful in controlling problems related to gases in the body.

CONCEPT:

Logic Gates:

• The logic gates are used in electronic circuits that give a certain output for a given set of Inputs.
• and which is based on a certain logic. 
• Input and output are in binary form that is 1 and 0.
• It is based on certain Logic.
• Some basic logic gates are AND gate, OR gate, NOT gate. 
• To build digital logic we develop a combination of these gates. 

AND Gate

•  If both the inputs are high, it produces a high output.
• The Boolean algebra for AND gate is X = A. B
• It means that if any of the input of A and B is zero, the output will be zero.
• If both are one, the output will be one.

The correct option is AND Gate. 

Additional Information

NOT gate:  

• It inverts the input. Whatever the input is given, it changes its value at the output.
• The Boolean algebra for NOT gate is X = X̅

The correct answer is 192.10.23.350.

• Any address that begins with a 0 is invalid.
  • Exception - as a default route
• Any address with a number above 255 is invalid IP.
• Any address that has more than 3 dots is invalid IP.
• Any address that begins with a number between 240 and 255 is reserved and is invalid.
• Any address that begins with a number between 224 and 239 is reserved for multicast, and it is probably invalid.

Key Points

• An Internet Protocol address (IP address) is a numerical number assigned to every computer and device.
• It is used when connected to a computer network that uses the Internet Protocol for communication.
• An IP address serves two main functions:
  • host or network interface identification
  • location addressing.
