Question Discussion & Solution

Given: MADRAS is coded as NBESBT.

Logic: Adding 1 to the positional values of the letter, as shown below:

Similarly,

Hence, CPNCBZ is the correct answer.

Concept:-

• Plants have diverse varieties.
• There are more than 3 lakh plants species that have already been found in the world.
• Plants are beneficial in human life they give food, shelter and fulfil many other needs of various organisms.

Explanation:-

Bryophytes:

• Bryophytes are often referred to as the amphibians of the plant kingdom.
• Bryophytes are small, non-vascular plants.
• The reproduction of Bryophytes is via spores.
• Bryophytes are live in the soil, even though they need water for sexual reproduction this is the reason why the Bryophytes are often referred to as the amphibians of the plant kingdom.
• Bryophytes are generally classified into three coordinate phyla namely the liverworts, hornworts, and mosses.
• The following division, bryophytes, were the first land occupying or inhabiting plants.
• They fill in sodden or damp regions since they require water for fertilization.
• Consequently, they are called the creatures of land and water of the plant kingdom or the amphibians of the plant kingdom.

Thus, the first plants to inhabit the land are Bryophytes.

Additional Information 

Kingdom plants are divided into five groups- Thallophytes, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms.

Thallophyta

• The plant body is not differentiated from roots, stems, and leaves.
• They are commonly called algae.

Bryophyta

• These are small terrestrial plants.
• They show differentiation in the body design, with stem, leaf-like structures, and root-like structures.

Pteridophyta

• The plant body is differentiated into roots, stems, and leaves, apart from having a specialized tissue for conduction.

Gymnosperms

• Gymnosperms are plants with naked seeds.

Angiosperms

• Angiosperms are seed-bearing plants. Seeds develop inside tissues that get modified to form the fruit of the plant. 

Mammalogist is a person who studies about mammals. Similarly,

Concept:

• Food comprises constituents like proteins, carbohydrates, fats and supplementary substances such as minerals, vitamins and water that are vital for life.
• These constituents are known as nutrients. For proper functioning of our body, we need to consume bodybuilding foods (e.g. milk, meat, poultry, fish, eggs, pulses, groundnuts); energy-giving foods (e.g. cereals, sugar, roots, fats and oils); and protective foods (e.g. vegetables, fruits).

Explanation:

• Carbohydrates are the main source of energy for our body.
• Carbohydrates are of two types – simple and complex.
• Simple carbohydrates - These are quick-energy foods, e.g. sugar. Sources of simple carbohydrates are natural fruits, milk and milk products, and vegetables including potatoes and carrots.
• Complex carbohydrates - These are better sources of energy than sugar since they are released slowly. Sources of complex carbohydrates are bread, cereals (rice, wheat, bajra, corn, barley, ragi, sorghum, millets etc.),

Gram is not a source of carbohydrate, it is a source of protein.

Additional Information

Proteins:

• proteins are obtained from the animal as well as vegetable sources. Proteins of animal origin are found in milk, eggs, cheese, fish and meat.
• Proteins from these sources contain all the essential amino acids (EAA) in adequate amounts.
• Vegetable proteins are found in pulses (legumes), cereals, beans, nuts, oilseeds, etc

The correct answer is Velocity, time, and acceleration.

The first equation of motion gives the relation between initial velocity, final velocity, acceleration, and time.

• First equation of motion is given as v = u + at
  • Where, v = final velocity
  • u = initial velocity
  • a = acceleration
  • t = time taken

• The first equation of motion gives the value of velocity acquired by the body at any particular point of time t.
• The second equation of motion is given as s = ut + ½at²
• It gives the value of distance (s) traveled by a body at a given time t.
• Third equation of motion is given as v² = u² + 2as
• This equation gives the velocity of the body in traveling the distance s.
