Question Discussion & Solution

Binary search algorithm:

Binary search algorithm is used to find an element in an already sorted array.

STEPS 1:

It finds the middle element of the array and compare the element with the element to be searched, if

it matches then return true.

STEPS 2:

If not, then divide the array into two halves in which if element to be search is less than middle

element then search takes place in left part otherwise search in right half.

STEP 3:

Repeat this process, until you get the element.

Explanation:

Best case of Binary search occurs when element to be searched is the middle element of the array.

Then in that case, it just simply compares the element with the middle element, if matches then return

true.  Comparing with the one element will take only O(1) time complexity.

Best Case: Search 35 in below give array

T(n) = O(1)

The correct answer is Fermentation.

Key Points

• Fermentation:
  • The biological process, in which sugar molecules are converted into ethyl alcohol and carbon dioxide with the help of some microbes like yeast and bacteria is called alcohol fermentation.
  • It is an anaerobic process. i.e. it occurs in the absence of oxygen.
  • The process is governed by the enzyme alcohol dehydrogenase
  • Alcoholic fermentation has many uses such as for the production of alcoholic beverages, ethanol fuel, and bread cooking.

Additional Information

• Moulding:
  • ​Moulding is a typical process in which a type of fungus that grows surface of fruits and vegetable.
  • These tubular branches have multiple, genetically identical nuclei, yet form a single organism, known as a colony.
  • In contrast, yeast is a type of fungus that grows as a single cell.
• Nitrogen Fixation:
  • Nitrogen fixation is the chemical process by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle. 
  • Atmospheric nitrogen is fixed by several methods like biological N2 fixation, Industrial N2 fixation & Electrical N2 fixation.
  • It is a necessary process, as the fixed nitrogen is used in the biosynthesis of several organic compounds like amino acids, proteins, nucleic acids, etc.
• Transcription:
  • ​The process of copying genetic information from one strand of DNA into RNA is termed transcription or mRNA synthesis.
  • The process of transcription begins when an enzyme called RNA polymerase attaches to the template DNA strand and begins to catalyze the production of complementary RNA.
  • It is completed in three steps Initiation, Elongation & Termination.

Curator means in charge of a museum similarly Warder is in charge of Prison.

In the fig. 1, in the top part of the plus, a curved arrow is placed and the adjacent triangle is filled. And at the bottom of the square, a callout is placed.

In the fig. 2, in the left part of the plus, a curved arrow is placed after rotating anticlockwise and the filled triangle is swapped. And in the right part of the plus, a callout is placed.

In the fig.3, in the bottom part of the plus, a curved arrow is placed after rotating anticlockwise and the filled triangle is swapped. And in the top part of the plus, a callout is placed.

In the fig.4, in the right part of the plus, a curved arrow is placed after rotating anticlockwise and the filled triangle is swapped. And in the left part of the plus, a callout is placed.

The correct answer is ​Uttar Pradesh.

• Uttar Pradesh is the highest milk-producing state of India.

Key Points

• It produces around 18% of the country's total milk production.
• It is followed by Rajasthan which produces 11%, Andhra Pradesh producing 10%, Gujarat at 8% and Punjab produces 7%.
• India produces around 146 million MT of milk and is the largest producer of milk worldwide.
• Indian Dairy market is considered to be the largest and fastest-growing market in the world.
• India also exports around 0.2 billion USD which includes products like skimmed milk powder korma cream etc.
• The major countries are UAE, Bangladesh and other Southeast Asian countries.
