    • The ionosphere is a layer located in the thermosphere, extending from 60 km to 1000 km above the Earth's surface.
    • Gas molecules in this layer absorb X-rays and ultraviolet rays from the Sun, resulting in high temperatures that break up gas molecules into ions (positive and negative charges).
    • This process leads to the presence of electrically charged particles in the ionosphere.
    • The ionosphere is ionized by solar and cosmic radiation.
    • One of the key functions of the ionosphere is to reflect radio waves back to Earth, enabling long-distance communications.
    • Auroras occur in the ionosphere due to the presence of ions.

Important Points:

  • Atmosphere:
    • The atmosphere is the envelope of air surrounding Earth, held in place by Earth's gravitational force.
    • It comprises five distinct layers, each with unique characteristics and functions.

Additional Information:
Troposphere

  • First layer of the atmosphere, extending up to 16 km above Earth's surface.

  1. Public Distribution System (PDS)
  2. Minimum Support Price (MSP)
  3. Maintenance of Buffer Stock

Select the correct answer using the code given below.

Detailed Solution for BPSC Prelims Mock Test - 4 - Question 5
  • Public Distribution System (PDS):
    • The Public Distribution System (PDS) is an Indian food security system established under the Ministry of Consumer Affairs, Food, and Public Distribution.
    • PDS evolved as a system of managing scarcity through the distribution of food grains at affordable prices.
    • It has helped stabilize food prices and make food available to the poor at affordable prices.
    • It maintains the buffer stock of food grains in the warehouse to ensure a constant flow of food even during periods of low agricultural food production.
    • It aids in the redistribution of grains by supplying food from surplus regions of the country to deficient regions. Therefore, Option 1 is correct.
  • Minimum Support Price (MSP):
    • The MSP is the rate at which the government purchases crops from farmers, calculated at least one-and-a-half times the cost of production incurred by the farmers.
    • MSP serves as a "minimum price" for crops that the government deems remunerative for farmers and deserving of support.
    • The Commission for Agricultural Costs & Prices (CACP) recommends MSPs for 22 mandated crops and fair and remunerative prices (FRP) for sugarcane. Therefore, Option 2 is correct.
  • Buffer Stock:
    • Buffer stocks are a reserve of commodities like rice and wheat maintained to ensure food security and handle unforeseen emergencies like drought, famine, or wars.
    • In India, the public sector maintains buffer stocks.
    • Purchasing food grains from farmers at the Minimum Support Price (MSP) helps farmers avoid selling at a loss and ensures a fair return on their investment.
    • Buffer stocks of food grains are maintained to fulfill the goal of providing sufficient food for all Indians or preserving food security. Hence, Option 3 is correct.
BPSC Prelims Mock Test - 4 - Question 6

Which is NOT an example of one-sided symbiotic relationship?

Detailed Solution for BPSC Prelims Mock Test - 4 - Question 6

Understanding Symbiotic Relationships

  • Tapeworm in the host's stomach: This is NOT an example of a one-sided symbiotic relationship (Commensalism). It represents Parasitism, where the tapeworm benefits at the expense of the host.
  • Symbiosis: It refers to a close relationship between two species where at least one species benefits. The impact on the other species can be positive, negative, or neutral.
  • Types of Symbiotic Relationships:
    • Mutualism: This type involves both species benefiting from the relationship. For instance, the goby fish and shrimp have a mutualistic relationship.
    • Commensalism: In this relationship, one species benefits while the other remains unaffected. An example is mites hitching a ride on larger flying insects.
    • Parasitism: Here, one species (the parasite) benefits while the other (the host) is harmed. Roundworms parasitizing mammals like humans, cats, and dogs exemplify this relationship.
BPSC Prelims Mock Test - 4 - Question 7

Which of the following becomes difficult without a frictional force?

Detailed Solution for BPSC Prelims Mock Test - 4 - Question 7

  • Resistance to Motion: Friction can be described as the resistance to the motion of one object moving relative to another.
  • Role of Friction in Walking: When we walk, there is friction between our foot and the non-smooth surface. As we push the ground backward while walking, the frictional force acts in the opposite direction (forward direction), preventing our foot from slipping backward.
  • Friction on Wet Marble Floor: On a wet marble floor, the friction is significantly reduced due to the smooth surface. This lack of friction makes it challenging to move without slipping.

It is mandated to convene at least four times a year.- Inflation Targeting - Inflation targeting is a central banking policy that involves adjusting monetary policy to reach a specified annual inflation rate. This strategy is based on the premise that maintaining price stability is essential for long-term economic growth. Inflation targeting involves setting an inflation rate as a goal and adapting monetary policy to achieve that rate. Supporters believe that this approach not only maintains price stability but also fosters economic growth and stability. Inflation targeting differs from other central banking goals like targeting exchange rates, unemployment, or national income.- Members of the MPC - The six members of the Monetary Policy Committee are: - Ashima Goyal - Shashanka Bhide - Jayanth R.

Detailed Solution for BPSC Prelims Mock Test - 4 - Question 26

Decoding the Pattern

  • The pattern followed in the given codes is as follows:
    • F → 6; 6 + 1 = 7 (Positional value + 1)
    • L → 12; 12 + 1 = 13
    • O → 15; 15 + 1 = 16
    • W → 23; 23 + 1 = 24
    • E → 5; 5 + 1 = 6
    • R → 18; 18 + 1 = 19

Decoding FLOWER and FRUIT

  • Given codes:
    • F → 6; 6 + 1 = 7
    • R → 18; 18 + 1 = 19
    • U → 21; 21 + 1 = 22
    • I → 9; 9 + 1 = 10
    • T → 20; 20 + 1 = 21

    Therefore, FLOWER is coded as 7131624619 and FRUIT is coded as 719221021.

    • A → 1; 1 + 1 = 2
    • N → 14; 14 + 1 = 15
    • T → 20; 20 + 1 = 21

    Therefore, PLANT is coded as 171321521.

Therefore, the correct answer is 171321521.
