BMAT Trivia 4 — Questions and Answers
Question 1: Which law states that the pressure of a gas is inversely proportional to its volume at constant temperature?
- Charles's Law
- Avogadro's Law
- Boyle's Law (Correct answer)
- Gay-Lussac's Law
Correct answer: Boyle's Law
Boyle's Law: P₁V₁ = P₂V₂ at constant temperature, showing inverse proportionality between pressure and volume.
Question 2: Which organelle is known as the 'powerhouse of the cell' because it produces ATP?
- Ribosome
- Golgi apparatus
- Nucleus
- Mitochondria (Correct answer)
Correct answer: Mitochondria
Mitochondria carry out cellular respiration to produce ATP, the cell's main energy currency.
Question 3: What is the speed of light in a vacuum, to the nearest whole number in m/s?
- 3 × 10⁸ m/s (Correct answer)
- 3 × 10⁶ m/s
- 3 × 10¹⁰ m/s
- 3 × 10⁴ m/s
Correct answer: 3 × 10⁸ m/s
The speed of light in a vacuum is approximately 2.998 × 10⁸ m/s, rounded to 3 × 10⁸ m/s.
Question 4: A patient's blood type is AB positive. Which blood types can they receive?
- AB+ only
- A and B only
- All blood types (Correct answer)
- O only
Correct answer: All blood types
AB+ individuals are universal recipients and can receive blood from any ABO/Rh blood type.
Question 5: Which of Newton's laws states that every action has an equal and opposite reaction?
- First law
- Second law
- Third law (Correct answer)
- Fourth law
Correct answer: Third law
Newton's Third Law of Motion states that for every action force there is an equal and opposite reaction force.
Question 6: Which molecule carries amino acids to the ribosome during protein synthesis?
- mRNA
- rRNA
- DNA
- tRNA (Correct answer)
Correct answer: tRNA
Transfer RNA (tRNA) brings specific amino acids to the ribosome, matching anticodon to codon on mRNA.
Question 7: The price of a jacket is reduced by 20% to £64. What was the original price?
- £80 (Correct answer)
- £76.80
- £84
- £72
Correct answer: £80
If the reduced price is 80% of the original, then original = 64 / 0.80 = £80.
