• B. Although it was raining, the children played outside.
• C. When the sun rises, the birds begin to sing.

4. Which of the following is NOT a function of the integumentary system?

• A. Regulation of body temperature
• B. Protection from pathogens
• C. Synthesis of vitamin D
• D. Production of digestive enzymes

Correct answer: D

Rationale: The correct answer is D: "Production of digestive enzymes." The integumentary system primarily consists of the skin, hair, nails, and glands. Its main functions include regulating body temperature through processes like sweating and shivering, protecting the body from pathogens and external threats, and synthesizing vitamin D when exposed to sunlight. However, the production of digestive enzymes is not a function of the integumentary system. Digestive enzymes are primarily produced by organs such as the pancreas and salivary glands to aid in the breakdown of food in the digestive system, which is separate from the functions of the integumentary system.

5. Which of the following is an example of a decomposition reaction?

• A. 2H2 + O2 → 2H2O
• B. CaCO3 → CaO + CO2
• C. 2Na + Cl2 → 2NaCl
• D. N2 + 3H2 → 2NH3

Correct answer: b

Rationale: Decomposition reactions involve the breakdown of a compound into simpler substances.

6. What is the term for the involuntary muscle contractions that move food through the digestive tract?

• A. Segmentation
• B. Peristalsis
• C. Chyme
• D. Emulsification

Correct answer: B

Rationale: The correct answer is B: Peristalsis. Peristalsis is the term used to describe the involuntary muscle contractions that help move food through the digestive tract. These rhythmic contractions occur in the smooth muscles of the digestive system and help propel food and other substances like chyme through the esophagus, stomach, and intestines. Segmentation, choice A, refers to the mixing movements in the intestines that aid in digestion but do not move food along the tract. Chyme, choice C, is the semi-fluid mass of partially digested food that moves from the stomach to the small intestine. Emulsification, choice D, is the process of breaking down fats into smaller droplets to aid in digestion, but it is not directly related to the movement of food through the digestive tract.
