Chemistry
1. Which element is a good conductor of electricity but is not a metal?
- A. Copper
- B. Silver
- C. Graphite
- D. Gold
Correct answer: C
Rationale: While metals are known for their conductivity, some non-metals like graphite also exhibit this property due to their unique electronic structure
2. The formula for calculating ideal body weight (IBW) for men is IBW (kg) = 50 + 2.3 * (height in cm - 150). If a man is 180cm tall, what is his ideal body weight?
- A. 68kg
- B. 71kg
- C. 74kg
- D. 77kg
Correct answer: C
Rationale: Substitute the man's height (180cm) into the formula: IBW = 50 + 2.3 * (180 - 150) = 74kg.
3. Which phase of the employment process includes getting on the payroll and completing
- A. Orientation
- B. Induction
- C. Selection
- D. Recruitment
Correct answer: D
Rationale: The correct answer is D: Recruitment. Recruitment is the phase of the employment process where organizations actively seek out and attract potential candidates for job openings. This involves advertising the position, sourcing candidates, and conducting initial screenings. Once the recruitment process is complete and a candidate has been selected, they move on to the selection phase. Orientation, on the other hand, occurs after a candidate has been hired and involves familiarizing the new employee with the organization, its policies, and their role. Induction is often used interchangeably with orientation and refers to the process of integrating a new employee into the organization. Therefore, in this context, recruitment is the most appropriate phase that involves getting on the payroll and completing the initial steps to bring a new employee on board.
4. 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: 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.
5. What is the process of breaking down and rebuilding bone tissue called?
- A. Ossification
- B. Remodeling
- C. Calcification
- D. Osteoporosis
Correct answer: B
Rationale: The correct answer is B: Remodeling. Remodeling is the process of breaking down and rebuilding bone tissue. This process helps maintain bone strength and structure by replacing old or damaged bone with new bone. Ossification refers to the formation of bone tissue, not the breakdown and rebuilding process. Calcification is the deposition of calcium salts in tissues, not specifically related to bone tissue remodeling. Osteoporosis is a condition characterized by a decrease in bone density, but it is not the process of breaking down and rebuilding bone tissue.
6. Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.
- A. Electromagnetism
- B. Gravity
- C. Strong nuclear force
- D. Weak nuclear force
Correct answer: C
Rationale: Strong nuclear force. This incredibly powerful force overcomes the repulsive electrostatic force between protons and binds the nucleus together.
