1. Which element is used in jewelry due to its malleability and resistance to tarnish?

• A. Iron
• B. Copper
• C. Gold
• D. Silver

Correct answer: C

Rationale: Gold is the correct answer. Gold is a popular choice for jewelry due to its exceptional malleability, allowing it to be easily shaped into intricate designs. Moreover, gold is resistant to tarnish, ensuring the jewelry retains its beauty over time. Iron is not commonly used in jewelry due to its susceptibility to rusting. Copper is also not as popular in jewelry making as gold due to its tendency to tarnish and cause skin discoloration. While silver is used in jewelry, it is more prone to tarnish compared to gold, making it less ideal for long-lasting pieces.

2. Which of the following systems is responsible for transporting blood throughout the body?

• A. Respiratory
• B. Circulatory
• C. Nervous
• D. Digestive

Correct answer: B

Rationale: The correct answer is B: Circulatory. The circulatory system, made up of the heart, blood vessels, and blood, is responsible for transporting blood throughout the body. It plays a vital role in delivering oxygen, nutrients, hormones, and removing waste products from cells. The respiratory system, on the other hand, is responsible for gas exchange in the lungs. The nervous system transmits signals between different parts of the body, while the digestive system processes food and absorbs nutrients from it. Therefore, choices A, C, and D are incorrect as they are not primarily involved in the transportation of blood throughout the body.

3. How many daughter cells are formed from one parent cell during meiosis?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: D

Rationale: During meiosis, one parent cell produces four genetically distinct daughter cells. This occurs through two rounds of cell division, resulting in four haploid cells with half the number of chromosomes as the parent cell. Each daughter cell is genetically unique due to processes like crossing over and independent assortment during meiosis. Choice A is incorrect because meiosis results in multiple daughter cells. Choice B is incorrect because meiosis yields more daughter cells. Choice C is incorrect because meiosis produces four, not three, daughter cells.

4. Which of the following units is equivalent to a joule?

• A. Newton-meter (N·m)
• B. Watt (W)
• C. Kilogram (kg)
• D. Ampere (A)

Correct answer: A

Rationale: A joule is the SI unit of energy and work, defined as the work done by a force of one newton acting over a distance of one meter. Therefore, a joule is equivalent to a newton-meter (N·m), which represents the product of force (newton) and distance (meter). This unit reflects the energy transferred when a force of one newton moves an object one meter. Choice B, Watt (W), is the unit of power and is not equivalent to a joule. Choice C, Kilogram (kg), is a unit of mass. Choice D, Ampere (A), is the unit of electric current.

5. What is the name of the condition characterized by inflammation of the small intestine?

• A. Appendicitis
• B. Celiac disease
• C. Gastritis
• D. Crohn's disease

Correct answer: D

Rationale: A) Appendicitis is inflammation of the appendix, not the small intestine. B) Celiac disease is an autoimmune disorder triggered by gluten consumption that damages the small intestine, but it is not characterized by inflammation alone. C) Gastritis is inflammation of the stomach lining, not the small intestine. D) Crohn's disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract, but it commonly involves the small intestine. Symptoms of Crohn's disease include abdominal pain, diarrhea, weight loss, and fatigue.
