The immune system protects the body against infections and diseases by identifying and destroying pathogens.

Lysosomes contain enzymes that break down waste materials and cellular debris.

The skeletal system provides structure and protection for internal organs, making option 2 the correct answer.

The GDP growth rate of India is projected to be around 6.8% for 2023.

Kangchenjunga is the highest peak in India, standing at 8,586 meters.

The IUPAC name for CH3-CH2-COOH is propanoic acid, as it has three carbon atoms in the longest chain.

The IUPAC name for CH3COOH is acetic acid.

Latent heat of fusion (L) = Q / m = 334,000 J / 500 g = 668 J/g.

Latent heat of fusion (L) = Q/m = 2400 J / 80 g = 30 J/g.

The North Pole is located at 90°N latitude.

LCM of 4 and 6 is 12.

In an equilateral triangle, the median is equal to the side length, so it is 10 cm.

The total difference is 60° + 120° = 180°. This is 12 hours difference. Therefore, 6:00 AM + 12 hours = 6:00 PM.

120°E is 120/15 = 8 hours ahead. Therefore, 3:00 PM + 8 hours = 11:00 PM.

150 degrees East is 150/15 = 10 hours ahead of GMT. Therefore, 12:00 noon + 10 hours = 10:00 PM.

The time difference is (15° / 15°) = 1 hour. Therefore, it is 6:00 PM + 1 hour = 7:00 PM.

45°E corresponds to 45 / 15 = 3 hours ahead of GMT, so it will be 12:00 noon + 3 hours = 3:00 PM.

45°E is 45 * 4 = 180 minutes ahead of GMT, which is 3 hours. Therefore, 6:00 PM + 3 hours = 9:00 PM.

At 75°W, the time is 75° / 15° = 5 hours behind GMT. Therefore, 3:00 PM GMT - 5 hours = 10:00 AM.

90 degrees East is 6 hours ahead of GMT, so 6:00 AM + 6 hours = 12:00 PM.

The magnetic field around a straight conductor carrying current forms concentric circles around the wire.

The magnetic field around a straight current-carrying conductor forms concentric circles around the wire, as described by Ampère's circuital law.

The magnetic field (B) at the center of a circular loop is given by B = (μ₀ * I) / (2 * R). Using μ₀ = 4π x 10^-7 Tm/A, B = (4π x 10^-7 * 3) / (2 * 0.1) = 0.1 T.

The magnetic field at the center of a circular loop is given by B = (μ₀ * I) / (2 * R). Using μ₀ = 4π x 10^-7 Tm/A, B = (4π x 10^-7 * 5) / (2 * 0.1) = 0.1 T.

The magnetic field at the center of a circular loop is given by B = (μ0I)/(2r).

Using the lens formula and magnification formula, we find the magnification m = -v/u = -1.

Using the mirror formula, 1/f = 1/v + 1/u, we find v = -7.5 cm. Magnification (m) = -v/u = 7.5/15 = 0.5.

The Pradhan Mantri Ujjwala Yojana aims to provide LPG connections to women from Below Poverty Line (BPL) households to promote clean cooking fuel.

The main cause of ocean currents is a combination of wind patterns, Earth's rotation, and temperature differences.

A black body absorbs all radiation incident on it, making it an ideal emitter of thermal radiation.
