1. What effect does doubling the net force applied to an object have on its acceleration, assuming mass remains constant?

• A. Acceleration doubles
• B. Acceleration is halved
• C. Acceleration remains the same
• D. Acceleration quadruples

Correct answer: a

Rationale: According to Newton's second law (F = ma), if mass remains constant and force doubles, acceleration also doubles.

2. The kidneys are bean-shaped organs responsible for filtering waste products from the blood. What is the main nitrogenous waste product the kidneys eliminate?

• A. Carbon dioxide
• B. Ammonia
• C. Urea
• D. Glucose

Correct answer: C

Rationale: The correct answer is C: Urea. The kidneys filter waste products from the blood to maintain a proper balance of electrolytes and remove toxins. Urea is the main nitrogenous waste product formed from the breakdown of proteins in the liver. It is then excreted by the kidneys through urine. Carbon dioxide is a waste product of cellular respiration and is eliminated primarily through the lungs. Ammonia is a toxic compound that is converted to urea in the liver before being excreted by the kidneys. Glucose is a sugar that is normally reabsorbed by the kidneys and not excreted as waste.

3. What is the process of converting light energy into chemical energy called?

• A. Respiration
• B. Fermentation
• C. Photosynthesis
• D. Hydrolysis

Correct answer: C

Rationale: Rationale: - Respiration (Option A) is the process by which cells break down glucose to release energy. - Fermentation (Option B) is an anaerobic process that also involves the breakdown of glucose to release energy. - Hydrolysis (Option D) is a chemical process that involves the breakdown of molecules by adding water. Photosynthesis (Option C) is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is essential for the survival of plants and ultimately sustains life on Earth by providing oxygen for other organisms to breathe and serving as a source of energy in the food chain.

4. Which of the following is NOT typically found in healthy urine?

• A. Urea
• B. Glucose
• C. Creatinine
• D. Electrolytes

Correct answer: B

Rationale: Glucose is NOT typically found in healthy urine because the kidneys filter glucose from the blood, and any excess is excreted in the urine. In healthy individuals, the renal threshold for glucose reabsorption is low, so glucose should not be present in significant amounts in urine. On the other hand, urea, creatinine, and electrolytes are all normal components of urine. Urea is a waste product of protein metabolism, creatinine is a waste product of muscle metabolism, and electrolytes like sodium and potassium are essential for various bodily functions and are excreted in urine. Therefore, option B is the correct answer as glucose is not typically found in healthy urine.

5. What is the main function of the gallbladder?

• A. To store and concentrate bile
• B. To produce digestive enzymes
• C. To absorb nutrients
• D. To neutralize stomach acid

Correct answer: A

Rationale: Rationale: The gallbladder is a small organ located beneath the liver that plays a crucial role in the digestive system. Its main function is to store and concentrate bile, a digestive fluid produced by the liver. Bile is released from the gallbladder into the small intestine to help with the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, allowing it to be released in a controlled manner when needed to aid in the digestion of fatty foods. Therefore, option A is the correct answer as it accurately describes the main function of the gallbladder.

6. She reads about Path Goal theory. Which of the following behaviors is manifested by the

• A. Recognizes staff for going beyond expectations by giving them citations
• B. Challenges the staff to take individual accountability for their own practice
• C. Admonishes staff for being laggards.
• D. Reminds staff about the sanctions for non performance.

Correct answer: B

Rationale: The correct answer is B: 'Challenges the staff to take individual accountability for their own practice.' Path-Goal theory emphasizes the leader's role in motivating and guiding their team to achieve goals. This behavior aligns with the theory as it focuses on empowering employees to take ownership of their actions and responsibilities. By challenging staff to be individually accountable, the leader is providing clear direction and support, which can enhance motivation and performance within the team. Recognizing and rewarding staff for going beyond expectations (option A) would be more aligned with a transformational leadership style. Admonishing staff for being laggards (option C) and reminding staff about sanctions (option D) are not effective leadership behaviors according to the Path-Goal theory, as they do not focus on motivating and supporting employees to reach their goals.
