• Bhakra canal has been drawn from the Satluj River near Nangal.

Key Points

• It’s a concrete gravity dam located in Bilaspur, Himachal Pradesh.
• Govind Sagar reservoir is formed by the dam.
• The length of the dam is 518.25 m and the width of the dam is 9.1 m.
• The reservoir of the dam is known as Govind Sagar.
• Bhakra dam has created a 90 km long reservoir.
• Pandit Jawaharlal Nehru described the dam as the “New temple of resurgent India”.

The correct answer is All of the above.

• Air pollutants are mainly classified as primary and secondary.
• The pollutants which emit directly into the atmosphere and remain in the same chemical form are known as primary pollutants.
• The pollutants which undergo chemical changes in the atmosphere due to the reaction of two or more pollutants are known as secondary pollutants.
• Pollutants like sulphur dioxide, nitrogen dioxide, particulates fall under the category of primary pollutants.

Additional Information

The correct answer is It is a closed system.
Key Points

• Ecosystem:
  • Ecosystem, a natural resource system, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
  • An ecosystem is an open system that can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Hence, statement 3 is incorrect.
  • Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem.
  • The fundamental source of energy in almost all ecosystems is radiant energy from the Sun.
  • The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.e., they can use the energy of sunlight to convert carbon dioxide and water into simple, energy-rich carbohydrates.
  • The autotrophs use the energy stored within the simple carbohydrates to produce the more complex organic compounds, such as proteins, lipids, and starches, that maintain the organisms’ life processes.
  • The autotrophic segment of the ecosystem is commonly referred to as the producer level.

Additional Information

• The organic matter generated by autotrophs directly or indirectly sustains heterotrophic organisms.
• Heterotrophs are the consumers of the ecosystem; they cannot make their own food.
• They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs.
• All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.
• Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level, composed of those organisms that make their own food; the primary consumer level, composed of those organisms that feed on producers; the secondary consumer level, composed of those organisms that feed on primary consumers; and so on.
• The movement of organic matter and energy from the producer level through various consumer levels makes up a food chain.
• For example, a typical food chain in a grassland might be grass (producer) → mouse (primary consumer) → snake (secondary consumer) → hawk (tertiary consumer).
• Actually, in many cases the food chains of the ecosystem overlap and interconnect, forming what ecologists call a food web.
• The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.
• A food chain in which the primary consumer feeds on living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway.
• Both pathways are important in accounting for the energy budget of the ecosystem.

The correct answer is Nitrogen.

Key Points

• Nitrogen is the most abundant gas in Earth's atmosphere.
• The composition of gases in Earth's atmosphere:
  • Nitrogen(78.08%)
  • Oxygen(20.95%)
  • Argon(0.93%)
  • Carbon dioxide(0.036%)

Hint

• Code to remember the composition of gases in Earth's atmosphere is NO AC(Nitrogen, Oxygen, Argon, Carbon dioxide).

Key Points

The two major sources of energy can be classified:

• Conventional Sources
• Non-Conventional Sources

​

• Conventional sources of energy are those energies that have been predominantly in use for the better part of civilization.
• Non-conventional sources of energy are the up-and-coming energy sources.

Important Points

Difference Between Conventional and Non-conventional Sources of Energy: 

The average income of a country is calculated by dividing the national income by the population. This value, also known as per capita income, represents the average income per person in the country. It serves as a crucial indicator for comparing the economic well-being of different nations.

• World Book and Copyright Day is observed every year on April 23 to promote the habit of reading, writing, publishing and copyright.
• The first World Book Day was observed in 1995. International Decade of Indigenous Languages will be observed from 2022 to 32. The UNESCO theme of the World Book Day 2023 is ‘Indigenous Languages’.

The US Chamber of Commerce released the 12th edition of the International Intellectual Property (IP) Index, ranking 55 economies on their IP frameworks. India secured the 42nd position with a 38.64% overall score. The United States, the United Kingdom, and France topped the list, emphasizing the pivotal role of strong IP systems in economic development. The index evaluates the effectiveness of IP landscapes in fostering innovation and creative industries globally.

Fitch Ratings has reaffirmed the long-term issuer default rating (IDR) of "BBB-" for both State Bank of India (SBI) and Canara Bank, with a stable outlook. This rating reflects their adequate capacity to meet financial commitments, despite variations in risk appetite and loan growth patterns observed by Fitch.

Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hameoglobin.

Force - force of friction = mass × acceleration
250 - f = 30 × 4
f = 250 - 120
= 130N

The ciliary muscles change the focal length of the eye lens by changing its shape.

When a base is dissolved in water, it produces OH^- ions. These hydroxide ions are responsible for the basic properties of the solution and are involved in neutralizing acids in chemical reactions.

- 5 / 4 + x = -1

x = -1 + 5 / 4

x = (-4 + 5) / 4

x = 1 / 4

Given that, a =x³y² = x × x × x × y × y
and b = xy³ = x × y × y × y
∴ HCF of a and b = HCF (x³y²,xy³) = x × y × y = xy² 
[Since, HCF is the product of the smallest power of each common prime factor involved in the numbers]

[(x)²]^1/3]1/4

= [(x²)^1/12] (as 1/3 * 1/4 = 1/12)

= x^1/6 (as 2/12 = 1/6)

A is the correct option.The Jabala Upanishad, also called Jabalopanisad, is a minor Upanishad of Hinduism. The Sanskrit text is one of the 20 Sannyasa Upanishads, and is attached to the Shukla Yajurveda. The Jabala Upanishad is an ancient text, composed before 300 CE.
