Mixed-difficulty questions from across the Combined Science (Synergy) syllabus. Tap "Show answer" after each to check yourself.

Q1 · Difficulty 1/3

An atom of carbon has an atomic number of 6 and a mass number of 12. How many neutrons does it contain?

  1. A) 6
  2. B) 12
  3. C) 18
  4. D) 2
Show answer & explanation
✓ Answer: A — A) 6
The number of neutrons is calculated by subtracting the atomic number from the mass number: 12 − 6 = 6 neutrons. A common error is to confuse mass number with the number of neutrons directly.
Q2 · Difficulty 1/3

Power is measured in:

  1. Watts (W)
  2. Joules (J)
  3. Newtons (N)
  4. Seconds (s)
Show answer & explanation
✓ Answer: A — Watts (W)
Power is measured in watts; 1 W = 1 joule per second.
Q3 · Difficulty 1/3

Which structure controls what enters and leaves an animal cell?

  1. The cell membrane
  2. The cell wall
  3. The nucleus
  4. The vacuole
Show answer & explanation
✓ Answer: A — The cell membrane
The cell membrane is partially permeable and controls the movement of substances in and out of the cell. Animal cells do not have a cell wall.
Q4 · Difficulty 1/3

Compared with a solid, the particles in a gas are:

  1. Far apart and move quickly in random directions
  2. Closely packed
  3. Fixed in place
  4. In a regular pattern
Show answer & explanation
✓ Answer: A — Far apart and move quickly in random directions
Gas particles are far apart with no fixed arrangement and move quickly in random directions.
Q5 · Difficulty 1/3

Resistance is measured in:

  1. Ohms (Ω)
  2. Amps (A)
  3. Volts (V)
  4. Watts (W)
Show answer & explanation
✓ Answer: A — Ohms (Ω)
Resistance is measured in ohms (Ω).
Q6 · Difficulty 1/3

Which stain is commonly used to make the nucleus of plant cells visible?

  1. Iodine solution
  2. Distilled water
  3. Cooking oil
  4. Sodium chloride
Show answer & explanation
✓ Answer: A — Iodine solution
Iodine stains structures such as the nucleus, increasing contrast so they are easier to see.
Q7 · Difficulty 1/3

Density is calculated as:

  1. mass ÷ volume
  2. mass × volume
  3. volume ÷ mass
  4. mass + volume
Show answer & explanation
✓ Answer: A — mass ÷ volume
Density = mass ÷ volume (ρ = m/V).
Q8 · Difficulty 1/3

Which change of state is melting?

  1. Solid to liquid
  2. Liquid to gas
  3. Gas to liquid
  4. Liquid to solid
Show answer & explanation
✓ Answer: A — Solid to liquid
Melting is the change from solid to liquid as particles gain energy and can move past each other.
