Explanation

Carnivorous plants trap and digest insects to obtain nitrogen, especially in nutrient-poor soils.

Examples include Venus flytrap, pitcher plant, and sundew.

Explanation

Dolomite is a carbonate mineral composed of CaMg(CO₃)₂.

It contains both calcium and magnesium carbonates, making it a double carbonate salt.

Explanation

An electrical impulse causes the cardiac cell's resting potential to convert into an action potential.

This action potential leads to contraction of heart muscle cells, enabling the heart to beat.

Explanation

Sonorous materials produce a ringing sound when struck.

Metals are sonorous due to their ability to vibrate and transmit sound.

Explanation

Reforming is the process used to separate hydrogen from hydrocarbons (like methane or naphtha) by applying heat in the presence of a catalyst.

This is typically called steam methane reforming (SMR).

Explanation

According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let the third side be x.

Given sides: 6 cm and 14 cm

The third side x must satisfy:

1. x + 6 > 14 => x > 8

2. x + 14 > 6 => x > -8 (this is always true since x is positive)

3. 6 + 14 > x => x < 20

Combining these conditions:

8 < x < 20

Explanation

Given:

Side length of square = 31 meters

Perimeter formula: P = 4 × side

P = 4 × 31

P = 124 meters

Explanation

To find the price of 7 tube lights, first, calculate the cost of one tube light. Asad bought 12 tube lights for Rs. 6900.

Cost per tube light = Total cost / Number of tube lights

= 6900 / 12

= 575

Now, calculate the cost of 7 tube lights:

Cost of 7 tube lights = Cost per tube light * Number of tube lights

= 575 * 7

= 4025

Explanation

To find the greatest number that divides 36, 44, and 52 completely, we need to find their Highest Common Factor (HCF).

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 44: 1, 2, 4, 11, 22, 44

Factors of 52: 1, 2, 4, 13, 26, 52

The greatest common factor is 4.
