1. The formula for body mass index (BMI) is BMI = weight (kg) / height (m)^2. If a patient's BMI is 25 and their height is 1.7m, what is their weight?
- A. 34kg
- B. 45kg
- C. 56kg
- D. 68kg
Correct answer: C
Rationale: 56kg: Rearrange the formula to solve for weight: weight = BMI * height^2.
2. Which type of waves are capable of interference and diffraction?
- A. Longitudinal waves only
- B. Transverse waves only
- C. Electromagnetic waves only
- D. Both longitudinal and transverse waves
Correct answer: d
Rationale: Both longitudinal and transverse waves can exhibit interference and diffraction phenomena.
3. Which type of cell has a nucleus but lacks membrane-bound organelles?
- A. Plant cell
- B. Prokaryotic cell
- C. Animal cell
- D. Fungal cell
Correct answer: B
Rationale: The correct answer is B: Prokaryotic cell. Prokaryotic cells are characterized by having a nucleus, known as the nucleoid, which contains genetic material but lacks a membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Plant and animal cells (options A and C) are eukaryotic cells that have a nucleus and membrane-bound organelles. Fungal cells (option D) are also eukaryotic cells with a nucleus and organelles. Understanding the difference between prokaryotic and eukaryotic cells is essential in biology to grasp the diversity of cell structure and function.
4. Which word completes the sentence "He was ____ by the unexpected turn of events."
- A. elated (joyful)
- B. bewildered (confused)
- C. vindicated (justified)
- D. apathetic (uninterested)
Correct answer: B
Rationale: "Bewildered" best describes the confusion caused by the unexpected events.
5. Which term describes the quantity of matter in an object and is measured in kilograms or grams?
- A. Weight
- B. Mass
- C. Volume
- D. Density
Correct answer: B
Rationale: Mass is the term that describes the quantity of matter in an object. It is typically measured in kilograms or grams. Weight, on the other hand, is the force of gravity acting on an object and is measured in newtons. Volume is the amount of space an object occupies, typically measured in cubic units such as cubic meters or cubic centimeters. Density is the mass of an object per unit volume and is measured in units such as kilograms per cubic meter.
6. What property of a substance refers to its ability to be drawn into thin wires without breaking?
- A. Malleability
- B. Viscosity
- C. Ductility
- D. Conductivity
Correct answer: c
Rationale: Ductility is the property that describes a substance's ability to be drawn into thin wires without breaking.
