AKUEB SSC-I MCQs by Subject: Biology, Chemistry & Physics Sample Questions
Sample AKU-EB SSC-I MCQs from the three core science-group subjects — Biology, Chemistry and Physics — one set per subject so you can see what each section actually tests.
AKU-EB SSC-I's science group centres on three subjects: Biology, Chemistry and Physics. Here's a sample from each so you know what to expect before you start practising at scale.
Biology
1. The basic structural and functional unit of all living organisms is the:
- A) Tissue
- B) Cell ✅
- C) Organ
- D) Nucleus
2. Which organelle is primarily responsible for producing most of a cell's usable energy (ATP)?
- A) Ribosome
- B) Golgi apparatus
- C) Mitochondrion ✅
- D) Lysosome
3. In osmosis, water moves across a selectively permeable membrane from a region of:
- A) Low solute concentration to high solute concentration ✅
- B) High solute concentration to low solute concentration
- C) Equal concentration only
- D) High pressure to low pressure only
Chemistry
4. The number of protons in the nucleus of an atom is called its:
- A) Mass number
- B) Atomic number ✅
- C) Valency
- D) Isotope number
5. Elements in Group 18 of the periodic table (the noble gases) are generally unreactive because:
- A) They have no electrons
- B) They have a complete outer electron shell ✅
- C) They are radioactive
- D) They have no protons
6. Which of the following best describes an exothermic reaction?
- A) It absorbs heat from the surroundings
- B) It releases heat to the surroundings ✅
- C) It has no energy change
- D) It only occurs in solids
Physics
7. The SI unit of force is the:
- A) Joule
- B) Watt
- C) Newton ✅
- D) Pascal
8. A quantity that has both magnitude and direction is called a:
- A) Scalar
- B) Vector ✅
- C) Constant
- D) Coefficient
9. According to Newton's First Law of Motion, an object at rest will remain at rest unless acted upon by:
- A) Gravity alone
- B) A net external force ✅
- C) Friction only
- D) Its own mass
Why Subject-Wise Practice Works Better Than One Flat Pile
Biology, Chemistry and Physics test differently at SSC-I — Biology rewards precise terminology, Chemistry rewards understanding periodic trends and reaction types, and Physics rewards applying formulas correctly under time pressure. Practising them separately, with an explanation for every question, makes it easier to see which subject actually needs more of your revision time rather than assuming you're "generally okay at science."
HighYield's AKU-EB SSC-I question bank covers these three subjects plus Mathematics, General Mathematics, Computer Science, English, Civics, Business Studies and Principles of Accounting — all ten subjects, each MCQ with a written explanation.
