The ozone layer is a layer in Earth's atmosphere containing relatively high concentrations of ozone (O3). The ozone layer absorbs 97-99% of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which potentially damages exposed life forms on Earth.

Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations. This powerful hormone is part of the human body's acute stress response system, also called the "fight or flight" response. It works by stimulating the heart rate, contracting blood vessels, and dilating air passages, all of which work to increase blood flow to the muscles and oxygen to the lungs. Additionally, it is used as a medical treatment for some potentially life-threatening conditions including anaphylactic shock. In the US, the medical community largely refers to this hormone as epinephrine, although the two terms may be used interchangeably.

• Launched under the Aatmanirbhar Bharat Abhiyan, the Pradhan Mantri Formalisation of Micro food processing Enterprises (PM-FME) Scheme is a centrally sponsored scheme that aims to enhance the competitiveness of existing individual micro-enterprises in the unorganized segment of the food processing industry and promote formalization of the sector and provide support to Farmer Producer Organizations. Hence statements 1 and 2 are correct.
• Its objectives are:
  1. Increase in access to finance by micro food processing units,
  2. Increase in revenues of target enterprises,
  3. Enhanced compliance with food quality and safety standards,
  4. Strengthening capacities of support systems,
  5. Transition from the unorganized sector to the formal sector,
  6. Special focus on women entrepreneurs and Aspirational districts,
  7. Encourage Waste to Wealth activities and focus on minor forest produce in Tribal Districts.

Hence statement 3 is correct.

• Soil Health Card is a printed report that a farmer will be handed over for each of his holdings. It is provided to all farmers in the country at an interval of 2 years to enable to apply recommended doses of nutrients based on soil test values to realise improved and sustainable soil health and fertility, low costs and high profits. Hence statement 1 is correct.
• Soil samples are tested with respect to 12 parameters: o Macro Nutrients - Nitrogen(N), Phosphorus(P), Potassium(K). o Secondary Nutrients- Sulphur(S). o Micro Nutrients- Zinc (Zn), Iron(Fe), Copper(Cu), Mangnese(Mn), Boron(B). o Physical parameters- pH (potential of hydrogen), EC (electrical conductivity),OC (organic Carbon). Hence statement 2 is not correct.
• The recent study conducted by the National Productivity Council concluded that use of soil health card has helped farmers substantially reduce the cost of production and achieve higher production, thereby increasing farm income.
• Application of fertilisers as per the recommendation of soil health cards led to savings in nitrogen fertilisers such as urea, which resulted in reduction in the cost of cultivation. Hence statement 3 is correct.

5+7 = 12
12+(7+3=10) =22
22+(10+9=19) = 41
41+(19+27=46) = 87
87+(46+81=127) = 214

14/2 + 5 = 12
12/2 +7 = 13
13/2 + 11= 17.5
17.5/2+13 = 21.75

Father's wife → mother. Hence, the daughter of the mother means sister and sister's younger brother means brother. Therefore, the boy is the brother of Deepak.

The seating arrangement is as follows:

Therefore, right of P is X.

P^-3M⁺⁶S, R^-3O⁺⁶U, G^-3D⁺⁶J, K^-2I⁺⁴M.

Except KIM, all other groups follows similar pattern.

AB = 1 + 2 = 3 km 
BC = 9 - 5 = 4 km 
Now, in right triangle ABC, using Pythagoras theorem,
AB² + BC² = AC² 
3² + 4² = AC²
9 + 16 = AC²
25 = AC²
AC = 5 km
