BMAT Trivia 5 — Questions and Answers
Question 1: Which hormone regulates blood glucose levels by promoting uptake of glucose into cells?
- Glucagon
- Adrenaline
- Cortisol
- Insulin (Correct answer)
Correct answer: Insulin
Insulin, secreted by beta cells of the pancreas, facilitates glucose uptake by cells and lowers blood glucose.
Question 2: What type of electromagnetic radiation has the shortest wavelength?
- Radio waves
- Ultraviolet
- X-rays
- Gamma rays (Correct answer)
Correct answer: Gamma rays
Gamma rays have the shortest wavelength and highest frequency of all electromagnetic radiation.
Question 3: In which layer of the skin are new skin cells produced through cell division?
- Stratum corneum
- Stratum spinosum
- Stratum basale (Correct answer)
- Dermis
Correct answer: Stratum basale
The stratum basale (basal layer) is the deepest epidermal layer where mitosis continuously produces new keratinocytes.
Question 4: If f(x) = 3x² − 2x + 1, what is f(2)?
- 9 (Correct answer)
- 13
- 11
- 7
Correct answer: 9
f(2) = 3(4) − 2(2) + 1 = 12 − 4 + 1 = 9.
Question 5: Which of the following is NOT a function of the liver?
- Detoxification of alcohol
- Production of bile
- Secretion of insulin (Correct answer)
- Storage of glycogen
Correct answer: Secretion of insulin
Insulin is secreted by the beta cells of the pancreas, not the liver; the liver responds to insulin but does not produce it.
Question 6: What is the chemical formula for sulfuric acid?
- HCl
- HNO₃
- H₂SO₄ (Correct answer)
- H₃PO₄
Correct answer: H₂SO₄
Sulfuric acid has the formula H₂SO₄, containing two hydrogen, one sulfur, and four oxygen atoms.
Question 7: A bag contains 4 red balls and 6 blue balls. Two balls are drawn without replacement. What is the probability both are red?
- 2/15 (Correct answer)
- 4/25
- 1/6
- 2/5
Correct answer: 2/15
P(both red) = (4/10) × (3/9) = 12/90 = 2/15.
