1. Which of the following is NOT a function of the endocrine system?
- A. Regulating growth and development
- B. Maintaining blood sugar levels
- C. Controlling mood and emotions
- D. Facilitating digestion through muscle contractions
Correct answer: D
Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions. Option D, facilitating digestion through muscle contractions, is actually a function of the muscular and digestive systems, not the endocrine system. The endocrine system primarily regulates growth and development, maintains blood sugar levels through hormones like insulin and glucagon, and also plays a role in controlling mood and emotions through hormones such as serotonin and cortisol. Therefore, option D is correct as it is not a function directly associated with the endocrine system.
2. A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?
- A. 32mm
- B. 40mm
- C. 48mm
- D. 56mm
Correct answer: C
Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 6 * 8mm = 48mm.
3. What term describes the bouncing back of waves after striking a surface or boundary?
- A. Diffraction
- B. Refraction
- C. Reflection

4. Rectangle: A picture frame measures 15cm by 20cm. What is its perimeter?
- A. 30cm
- B. 55cm
- C. 65cm
- D. 75cm
Correct answer: C
Rationale: Add the lengths of all sides: perimeter = 2 (length + width) = 2 (15cm + 20cm) = 65cm.
5. Identify the pronoun in the following sentence: She quickly finished her homework before dinner.
- A. quickly
- B. finished
- C. her

6. Which mineral is crucial for bone strength and is stored in bones and teeth?
- A. Calcium
- B. Iron
- C. Magnesium
- D. Potassium
Correct answer: A
Rationale: The correct answer is A: Calcium. Calcium is crucial for bone strength as it is a key mineral stored in bones and teeth. It plays a vital role in maintaining bone density and strength, helping to prevent conditions like osteoporosis. Without an adequate intake of calcium, individuals may be at risk of developing weak and brittle bones. Iron (B), Magnesium (C), and Potassium (D) are important minerals for various bodily functions, but they are not primarily responsible for bone strength and storage in bones and teeth.
