1. A medication dosage is listed as 1/2 teaspoon. What is the equivalent dosage in milliliters (1 teaspoon = 5ml)?

• A. 1.25ml
• B. 2.5ml
• C. 3.75ml
• D. 5ml

Correct answer: B

Rationale: 2.5ml: Divide the teaspoon dosage (1/2) by the conversion factor (2 teaspoons/5ml).

2. Which of the following is NOT a common symptom of pregnancy?

• A. Fatigue
• B. Nausea
• C. Increased urination
• D. Loss of appetite

Correct answer: D

Rationale: The correct answer is D: "Loss of appetite." While it is common for pregnant individuals to experience fatigue, nausea, and increased urination due to hormonal changes and the body's adaptations during pregnancy, a loss of appetite is not typically a common symptom. Most pregnant individuals experience increased appetite, particularly in the early stages of pregnancy. This increased appetite is often attributed to the body's need for additional nutrients to support the growing fetus. Therefore, the absence of appetite loss makes option D the correct choice in this question.

3. In the reaction 4Al + 3O2 → 2Al2O3, what is the mole ratio of aluminum to oxygen?

• A. 4:3
• B. 2:3
• C. 3:2
• D. 3:4

Correct answer: a

Rationale: The coefficients in the balanced equation represent the mole ratio, which is 4 moles of Al to 3 moles of O2.

4. What is the general formula for an alkene?

• A. CnH2n+2
• B. CnH2n
• C. CnH2n-2
• D. CnH2n+1

Correct answer: B

Rationale: The general formula for an alkene is \(C_nH_{2n}\), indicating the presence of a double bond between carbon atoms.

5. What is the name of the curved bone in the back that provides support and attachment for muscles?

• A. Sternum
• B. Scapula
• C. Clavicle
• D. Vertebral column

Correct answer: D

Rationale: The correct answer is D: Vertebral column. The vertebral column, also known as the spine or backbone, is a series of small bones called vertebrae that provide support and protection for the spinal cord. It also serves as an attachment point for various muscles in the back. The sternum, scapula, and clavicle are all bones in the upper body, but they do not specifically provide support and attachment for muscles in the back like the vertebral column does.

6. The liver plays a vital role in digestion. What is one of the main functions of the liver in the digestive system?

• A. Physical breakdown of food
• B. Production of digestive enzymes
• C. Storage and processing of nutrients
• D. Elimination of waste products

Correct answer: C

Rationale: The correct answer is C: 'Storage and processing of nutrients.' The liver is a crucial organ in the digestive system as it performs various functions such as storing nutrients like glucose, vitamins, and minerals, processing nutrients by converting them into usable forms for the body, and regulating their distribution to different parts of the body. While the physical breakdown of food primarily occurs in the mouth and stomach, and the production of digestive enzymes mainly happens in the pancreas and small intestine, the liver's main role is to manage and store the nutrients obtained from the digested food. Therefore, option C is the correct choice for the main function of the liver in the digestive process.
