1. How is an ear infection that persists for less than 14 days classified?

• A. Mastoiditis
• B. Chronic Ear Infection
• C. Acute Ear Infection
• D. Otitis Media

Correct answer: C

Rationale: Acute Ear Infection is the correct answer because it typically refers to an infection that is short-lived and often severe, typically lasting less than 14 days. Chronic Ear Infection (Choice B) is incorrect as it refers to an ear infection that lasts for a long time or recurs often, typically more than three months. Mastoiditis (Choice A) is a complication of a middle ear infection and not an ear infection itself. Otitis Media (Choice D) is a general term for inflammation or infection in the middle ear, which can be either acute or chronic, so it's not specific enough to be the correct answer. Understanding the duration and severity of symptoms can help in identifying the type of ear infection, facilitating appropriate treatment and prevention of complications.

2. Does taste perception decline with age, and are individuals taking three or more medications likely to have less taste sensitivity, requiring greater amounts of sodium and sugar to perceive these tastes?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are indeed true. As people age, their taste perception tends to decline. This change can be further exacerbated by the use of multiple medications, which can potentially dull taste sensitivity even more. Consequently, these individuals often need to consume foods with higher levels of sodium and sugar in order to perceive these tastes. Choices B, C, and D are incorrect because they deny either one or both of these established facts.

3. Sickle cell disease is an example of an inherited mistake in the amino acid sequence.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.

4. Which food is a high source of prebiotics?

• A. Chicken
• B. Garlic
• C. White rice
• D. Cheese

Correct answer: B

Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.

5. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
