- A. While the movie was playing

2. The hormone responsible for the "fight-or-flight" response in stressful situations is produced by the:
- A. Thyroid gland
- B. Pituitary gland
- C. Adrenal gland
- D. Pancreas
Correct answer: C
Rationale: The correct answer is C: Adrenal gland. The adrenal gland is responsible for producing the hormone known as adrenaline, which triggers the 'fight-or-flight' response in stressful situations. This response prepares the body to either confront the stressor or flee from it. The thyroid gland (A) is responsible for producing hormones that regulate metabolism, growth, and development. The pituitary gland (B) controls several other endocrine glands and produces a variety of hormones. The pancreas (D) is responsible for producing insulin and glucagon, which regulate blood sugar levels but are not directly involved in the 'fight-or-flight' response.
3. What is the oxidation state of carbon in CH4?
- A. +1
- B. -1
- C. +2
- D. -4
Correct answer: d
Rationale: Each hydrogen atom has an oxidation state of +1, and the sum of oxidation states in CH4 is 0. Therefore, carbon has an oxidation state of -4.
4. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?
- A. Limiting high-sodium foods in the diet
- B. Consuming adequate amounts of cranberry juice
- C. Holding urine in the bladder for long periods
- D. Getting regular moderate-intensity exercise
Correct answer: C
Rationale: The correct answer is C: Holding urine in the bladder for long periods. This is not recommended for optimal urinary system health because it can increase the risk of urinary tract infections and bladder problems. It is important to empty the bladder regularly to prevent bacteria from multiplying and causing infections. Limiting high-sodium foods in the diet helps maintain kidney health by reducing the risk of kidney stones and high blood pressure. Consuming cranberry juice can help prevent urinary tract infections due to its antibacterial properties. Regular moderate-intensity exercise promotes overall health, including good circulation to the kidneys and bladder.
5. How many moles of water are produced when 0.5 moles of methane (CH4) react with excess oxygen?
- A. 0.5 moles
- B. 1 mole
- C. 2 moles
- D. 3 moles
Correct answer: c
Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, indicating a 1:2 ratio between CH4 and H2O.
6. Which property of a substance refers to its ability to be stretched into thin wires?
- A. Conductivity
- B. Viscosity
- C. Ductility
- D. Malleability
Correct answer: c
