VCE VCE Sciences 1 — Questions and Answers
Question 1: Which VCE Biology unit focuses on how living systems regulate internal environments?
- Unit 3 (Correct answer)
- Unit 1
- Unit 2
- Unit 4
Correct answer: Unit 3
VCE Biology Unit 3 covers how cells maintain a stable internal environment, including signal transduction and immune responses.
Question 2: In VCE Chemistry, what is a 'mole' used to measure?
- Amount of substance (Correct answer)
- Mass in grams
- Volume of gas
- Concentration of a solution
Correct answer: Amount of substance
A mole is the SI unit for amount of substance, equal to 6.022 × 10²³ entities (Avogadro's number).
Question 3: In VCE Physics Unit 3, which area of study covers motion and forces?
- How do things move and interact? (Correct answer)
- How are fields used to move electrical energy?
- How fast can digital information be transferred?
- How is radiation used to examine matter?
Correct answer: How do things move and interact?
VCE Physics Unit 3 Area of Study 1, 'How do things move and interact?', covers Newton's laws, momentum, and energy.
Question 4: What is the role of ATP in VCE Biology's study of cellular processes?
- It is the primary energy currency of the cell (Correct answer)
- It carries genetic information
- It catalyses metabolic reactions
- It forms the cell membrane
Correct answer: It is the primary energy currency of the cell
ATP (adenosine triphosphate) is the molecule used by cells to store and transfer energy for biochemical reactions.
Question 5: In VCE Chemistry, what does Le Chatelier's Principle describe?
- How a system at equilibrium responds to a stress (Correct answer)
- The rate of a chemical reaction
- The energy released in combustion
- The solubility of ionic compounds
Correct answer: How a system at equilibrium responds to a stress
Le Chatelier's Principle states that if a stress is applied to a system at equilibrium, the system shifts to counteract that stress.
Question 6: Which concept in VCE Physics describes the bending of light as it passes from one medium to another?
- Refraction (Correct answer)
- Reflection
- Diffraction
- Polarisation
Correct answer: Refraction
Refraction is the bending of light when it crosses the boundary between two media with different refractive indices.
