Free sample General Science MCQs (with answers)
1. The basic unit of biological classification is:
- A. Family
- B. Species
- C. Order
- D. Genus
Correct answer: B
Species is the most basic unit of biological classification.
2. Chemical digestion of carbohydrates (starch) begins in which organ?
- A. Mouth
- B. Stomach
- C. Small intestine
- D. Liver
Correct answer: A
Saliva in the mouth contains amylase, the enzyme that starts breaking starch into simpler sugars. The stomach and small intestine continue digestion later.
3. The distance between two consecutive compressions of a sound wave is its:
- A. Frequency
- B. Amplitude
- C. Wavelength
- D. Pitch
Correct answer: C
Wavelength is the distance between successive compressions (or rarefactions) of a longitudinal sound wave.
4. Digestion of food begins in the:
- A. stomach
- B. mouth
- C. small intestine
- D. liver
Correct answer: B
Saliva begins breaking down starch as soon as food is chewed, so the mouth is where digestion starts; the stomach continues it later.
5. Heat travels fastest through:
- A. air
- B. water
- C. metals
- D. wood
Correct answer: C
Metals are good conductors because free electrons carry heat quickly; air, water and wood are poor conductors and act as insulators.
6. What does the abbreviation CPU stand for?
- A. Central Programming Unit
- B. Core Program Utility
- C. Computer Processing Unit
- D. Central Processing Unit
Correct answer: D
CPU stands for Central Processing Unit, the primary component that executes instructions.
7. The speed of sound in air is approximately:
- A. 332 m/s
- B. 150 m/s
- C. 300 000 km/s
- D. 1000 m/s
Correct answer: A
At ordinary room temperature, sound travels through air at roughly 332 metres per second.
8. Which part of a flower produces pollen?
- A. Stamen (anther)
- B. Carpel (stigma)
- C. Sepal
- D. Ovary
Correct answer: A
The anther of the stamen produces pollen grains.
