The correct answer is option 3 i.e. 0.

(15)⁵ ÷ (225)² × 3375 ÷ (15)⁶ = 15^{(? – 2)}

⇒ (15⁵ ÷ 15⁴⁾ × (15³ ÷ 15⁶)= 15^{(? – 2)}

Applying BODMAS Rule;

⇒ 15 × 15 ^{- 3} = 15^{(? – 2)}

⇒ 15 ^{- 2} = 15^{(? – 2)}

⇒ ? – 2 = - 2

⇒ ? = 0

The correct answer is option 2 i.e. D.

In the given figures A, B and C: One shape is intersecting the other shape.

But in figure D, both shapes are apart from each other and not intersecting.

Hence, Figure D is the odd one.

Hence, the correct answer is D.

The correct answer is option 1 i.e. 297.

The series follows the following pattern:

3³ - 3² = 18

5³ - 5² = 100

7³ - 7² = 294

9³ - 9² = 648

11³ - 11² = 1210

Hence, the correct answer is 297.

The correct answer is option 2 i.e 2, 3, 4, 1

The correct answer is option 3 i.e. Mahanadi.

The correct answer is Option 2 i.e. Chloride.

In cystic fibrosis, the primary ion affected is chloride. Mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene disrupt the function of the CFTR protein, which is responsible for regulating the movement of chloride ions across cell membranes. This disruption leads to reduced chloride secretion and increased sodium absorption, resulting in dehydrated and thickened mucus secretions in various organs, particularly the lungs and digestive system. This thick mucus impairs normal function and makes patients susceptible to infections and other complications.

The correct answer is option 1 i.e. Joule.

The correct answer is option 3 i.e. Walking on a wet marble floor.

The correct answer is Option 1 i.e. does not apply to other organisms besides green plants.

• Photosynthesis is the process whereby phototrophs harness light energy and convert it into chemical energy, essential for powering cellular functions.
• This energy is stored in sugars formed from water and carbon dioxide.
• Not limited to green plants, photosynthesis is also observed in various prokaryotes like cyanobacteria, purple bacteria, and green sulfur bacteria.
• Glucose, the end product of photosynthesis, serves as fuel for cellular activities, with oxygen released as a by-product.
• The process comprises two stages: light-dependent reactions, occurring in daylight, and light-independent reactions, also known as the Calvin cycle or dark reactions.
