1. How do the digestive system and urinary system work together?

• A. The digestive system controls the function of the ureter.
• B. The urinary system removes toxins from the products of digestion.
• C. The digestive system manufactures hormones that influence urination.
• D. The urinary system eliminates some waste products of digestion.

Correct answer: D

Rationale: The correct answer is D because the urinary system eliminates some waste products of digestion. After digestion in the digestive system, nutrients are absorbed into the bloodstream, and waste products are transported to the kidneys via the urinary system to be excreted as urine. This process helps eliminate waste products generated during digestion, illustrating the coordination between the digestive and urinary systems. Choices A, B, and C are incorrect. Choice A is incorrect as the ureter is part of the urinary system, not controlled by the digestive system. Choice B is incorrect as the urinary system primarily removes metabolic waste, not toxins from digestion. Choice C is incorrect because the digestive system mainly aids in digestion and nutrient absorption, not hormone production affecting urination.

2. Which of the following percentages is equal to 0.45?

• A. 4.5%
• B. 0.045%
• C. 0.45%
• D. 45%

Correct answer: D

Rationale: To convert 0.45 to a percentage, you multiply by 100: 0.45 × 100 = 45%. Therefore, the correct answer is D. 45%. Choice A, 4.5%, is incorrect. This percentage would be equal to 0.045, not 0.45. Choice B, 0.045%, is also incorrect. It represents 0.045, not 0.45. Choice C, 0.45%, is very close to the correct answer but actually represents 0.0045, not 0.45.

3. What is implied about the rainforest's role in global climate?

• A. The rainforest has little impact on the climate.
• B. The rainforest plays a crucial role in regulating the climate.
• C. The rainforest is mainly important for biodiversity.
• D. The rainforest's destruction has no global consequences.

Correct answer: B

Rationale: The rainforest plays a crucial role in regulating the global climate by absorbing carbon dioxide. The extract highlights the fact that trees take in carbon dioxide and give off oxygen. When trees are cut down, the amount of carbon dioxide increases, contributing to global warming. This emphasizes the significant impact of rainforests on the climate. Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.

4. What does 'defecate' mean?

• A. To retain feces
• B. To expel feces
• C. To eliminate fluid
• D. To excrete mucus

Correct answer: B

Rationale: The correct answer is B: 'To expel feces.' Defecate refers to the act of eliminating solid waste from the body. Choice A, 'To retain feces,' is incorrect as defecation involves getting rid of feces. Choices C and D, 'To eliminate fluid' and 'To excrete mucus,' are also incorrect as they do not accurately define the term 'defecate.'

5. Which hormone is released during the body's fight-or-flight response?

• A. Insulin
• B. Adrenaline
• C. Thyroxine
• D. Cortisol

Correct answer: B

Rationale: Adrenaline, also known as epinephrine, is released during the body's fight-or-flight response. This hormone prepares the body for rapid action by increasing heart rate, dilating airways, and redirecting blood flow to essential organs in response to stress or danger. Insulin is not released during the fight-or-flight response; its primary role is to regulate blood sugar levels. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism, and cortisol is released in response to stress to regulate various bodily functions, but adrenaline is the hormone specifically associated with the fight-or-flight response.
