1. What is the technical term for the involuntary muscular contractions that move food through the digestive tract?

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

Correct answer: B

Rationale: Peristalsis is the term used to describe the involuntary muscular contractions that move food through the digestive tract. This process involves rhythmic contractions and relaxations of the muscles in the digestive system, which help propel food from the esophagus to the stomach and through the intestines for digestion and absorption of nutrients. Segmentation refers to the mixing movements in the intestines that aid in the absorption of nutrients but is not the term for the movement of food through the digestive tract. Chylification is not a recognized term in digestive physiology. Emulsification is the process of breaking down fat globules into smaller droplets to aid in digestion, not the movement of food through the digestive tract.

2. What is the medical term for a urinary tract infection (UTI)?

• A. Nephritis
• B. Cystitis
• C. Urethritis
• D. All of the above

Correct answer: B

Rationale: The medical term specifically used to refer to a urinary tract infection (UTI) that affects the bladder is cystitis. Nephritis refers to inflammation of the kidneys, and urethritis refers to inflammation of the urethra. As such, cystitis is the correct term for a UTI, making choice B the right answer. Choices A, C, and D are incorrect because they refer to different conditions affecting the urinary system.

3. Mrs. Jones's class is conducting an experiment. They will substitute artificial sweetener for sugar in a cookie recipe to determine the effect on the overall color of the baked cookies. Which of the following should be included in the instructions for the experiment?

• A. When preparing the batch that includes artificial sweetener, 20% more water should be included.
• B. The bake temperature should be decreased from 425°F to 400°F.
• C. The batch with artificial sweetener should be baked on a stainless steel sheet.
• D. Ingredient proportions, bake time, bake temperature, and cookie sheet material should all be kept the same between the two batches.

Correct answer: D

Rationale: To ensure a valid comparison and isolate the impact of the artificial sweetener, the experiment should maintain consistency in all factors except the sugar substitution. By keeping ingredient proportions, bake time, bake temperature, and cookie sheet material the same, any observed differences in the color of the cookies can be attributed to the artificial sweetener rather than other variables. Choices A, B, and C introduce additional variables that could confound the results. Choice A would alter the consistency of the recipe by adjusting the water content, Choice B would introduce a change in baking temperature which could affect the outcome, and Choice C suggests a change in the type of baking sheet used, potentially impacting the baking process and results. Therefore, maintaining consistency in all other factors except for the sugar substitution is crucial for a reliable experiment.

4. Which type of tissue provides support and structure to the body?

• A. Muscle tissue
• B. Connective tissue
• C. Nervous tissue
• D. Epithelial tissue

Correct answer: B

Rationale: Connective tissue is the correct answer as it provides support, structure, and strength to the body by holding tissues and organs in place. Muscle tissue is primarily responsible for movement, nervous tissue for communication, and epithelial tissue for covering and lining surfaces. While muscle tissue allows for voluntary and involuntary movement, nervous tissue transmits electrical signals, and epithelial tissue acts as a protective barrier and is involved in absorption and secretion. Therefore, in the context of providing support and structure, connective tissue is the most appropriate choice.

5. Which of the following pathologies is caused by a virus?

• A. Asthma
• B. Cystic Fibrosis
• C. Epiglottitis
• D. Influenza

Correct answer: D

Rationale: The correct answer is D, Influenza. Influenza is a viral infection caused by the influenza virus. Asthma and cystic fibrosis are not caused by viruses. Asthma is a chronic respiratory condition related to inflammation and airway constriction, while cystic fibrosis is a genetic disorder affecting the lungs and other organs. Epiglottitis is most commonly caused by bacteria, particularly Haemophilus influenzae type B, rather than a virus.
