1. Which of the following processes represents a different level of defense compared to the others?

• A. A low pH in the stomach
• B. Cilia present in the trachea
• C. Body cells recognizing a pathogen
• D. Mucus present in the nasal cavity

Correct answer: C

Rationale: Among the listed processes, low pH in the stomach, cilia in the trachea, and mucus in the nasal cavity serve as physical barriers that form the first line of defense against pathogens. These barriers work to block pathogens from entering the body. On the other hand, body cells recognizing a pathogen involves the immune response, which operates at a different level of defense. This process is part of the adaptive immune response, where the body's immune cells identify, target, and eliminate specific pathogens to provide a specialized defense after the pathogens have breached the physical barriers. Therefore, body cells recognizing a pathogen represent a different level of defense compared to the other listed processes.

2. A synonym is a word _____ a meaning similar to another word.

• A. that has
• B. that gives
• C. which has
• D. which gives

Correct answer: A

Rationale: The correct phrase to use in this context is 'that has,' indicating possession or similarity between words. Synonyms are words that have meanings similar to those of other words, making choice A the most appropriate selection. Choices B, C, and D are incorrect as they do not correctly convey the relationship of possessing similar meanings between words.

3. What is the primary function of the small intestine in digestion?

• A. Breaking down fats
• B. Absorbing nutrients
• C. Secreting digestive enzymes
• D. Storing bile

Correct answer: B

Rationale: The correct answer is B: Absorbing nutrients. The small intestine plays a crucial role in digestion by absorbing nutrients. It is where the majority of nutrient absorption occurs, allowing digested food to pass into the bloodstream for distribution to the body's cells. Choice A (Breaking down fats) is incorrect because the breakdown of fats primarily occurs in the small intestine with the help of bile from the liver and enzymes from the pancreas. Choice C (Secreting digestive enzymes) is incorrect because while the small intestine does produce some digestive enzymes, its primary role is absorption. Choice D (Storing bile) is incorrect as the storage of bile occurs in the gallbladder, not the small intestine.

4. What does 'Ingest' mean?

• A. To chew
• B. To swallow for digestion
• C. To spit out
• D. To vomit

Correct answer: B

Rationale: The correct answer is B: 'To swallow for digestion.' Ingest means to take food, drink, or another substance into the body by swallowing it. Choice A, 'To chew,' is incorrect as chewing is the act of breaking down food with the teeth. Choice C, 'To spit out,' is incorrect as it is the opposite of ingesting, involving expelling something from the mouth. Choice D, 'To vomit,' is also incorrect as vomiting is forcibly expelling the contents of the stomach through the mouth, which is the opposite of ingesting.

5. How many millimeters are in 4 meters?

• A. 400 mm
• B. 4000 mm
• C. 40 mm
• D. 100 mm

Correct answer: B

Rationale: To convert meters to millimeters, you need to know that there are 1000 millimeters in 1 meter. Therefore, to find out how many millimeters are in 4 meters, you multiply 4 (meters) by 1000 (millimeters per meter), which equals 4000 millimeters. Choice A, 400 mm, is incorrect because it represents 4 decimeters, not 4 meters. Choice C, 40 mm, is incorrect because it represents 4 centimeters, not 4 meters. Choice D, 100 mm, is incorrect because it represents 1 meter, not 4 meters.
