**NEET Mock Test for PCB with Solutions**

Preparing for the NEET exam requires rigorous practice and thorough understanding of the concepts in Physics, Chemistry, and Biology. Taking mock tests is an excellent way to assess your knowledge and identify areas that need improvement. Here is a mock test for PCB (Physics, Chemistry, and Biology) with solutions for NEET preparation:

**Physics**

1. A car accelerates uniformly from rest to a speed of 25 m/s in 10 seconds. Calculate its acceleration.
- Solution: The formula to calculate acceleration is a = (v - u) / t, where v is the final velocity, u is the initial velocity, and t is the time taken. Plugging in the given values, we get a = (25 m/s - 0 m/s) / 10 s = 2.5 m/s².

2. A ball is thrown vertically upwards with an initial velocity of 20 m/s. How high will it go? (Take g = 9.8 m/s²)
- Solution: The maximum height reached by the ball can be calculated using the formula h = (v² - u²) / (2g), where v is the final velocity, u is the initial velocity, and g is the acceleration due to gravity. Plugging in the given values, we get h = (0 - 20²) / (2 * -9.8) = 20.41 m.

**Chemistry**

1. Which of the following is an example of a redox reaction?
- a) AgNO₃ + NaCl → AgCl + NaNO₃
- b) 2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
- c) CaCO₃ → CaO + CO₂
- d) 2 H₂ + O₂ → 2 H₂O
- Solution: Option (d) is an example of a redox reaction where hydrogen gas (H₂) is oxidized to form water (H₂O) by gaining oxygen from the oxygen gas (O₂).

2. The molar mass of glucose (C₆H₁₂O₆) is:
- a) 90 g/mol
- b) 120 g/mol
- c) 180 g/mol
- d) 240 g/mol
- Solution: To calculate the molar mass of glucose, we sum up the atomic masses of all the elements present. The atomic masses are: C = 12 g/mol, H = 1 g/mol, and O = 16 g/mol. Therefore, the molar mass of glucose is 6(12) + 12(1) + 6(16) = 180 g/mol.

**Biology**

1. Which of the following is NOT a function of the liver?
- a) Detoxification of harmful substances
- b) Production of bile
- c) Storage of glucose as glycogen
- d) Production of red blood cells
- Solution: Option (d) is incorrect as the liver does not produce red blood cells. Red blood cells are produced in the bone marrow.

2. Which of the following is responsible for carrying oxygen in red blood cells?
- a) Hemoglobin
- b) Plate
