1. Which element is found in water and is crucial for biological functions like nerve impulses and muscle contraction?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Sodium plays a key role in maintaining electrolyte balance and transmitting nerve impulses, affecting both muscles and nerves

2. 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.

3. What are the building blocks of proteins?

• A. Sugars
• B. Fatty acids
• C. Amino acids
• D. Nucleotides

Correct answer: C

Rationale: Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (A) are the building blocks of carbohydrates, fatty acids (B) are the building blocks of lipids, and nucleotides (D) are the building blocks of nucleic acids like DNA and RNA.

4. Temperature Conversion & Interpretation: A patient's body temperature is 102°F. Convert this to °C and assess if it indicates a fever.

• A. 37°C (Normal)
• B. 39°C (Low-grade fever)
• C. 39°C (Fever)
• D. 42°C (Hyperthermia)

Correct answer: C

Rationale: Rationale: 1. To convert Fahrenheit to Celsius, you can use the formula: °C = (°F - 32) x 5/9. 2. Given that the patient's body temperature is 102°F, we can calculate the equivalent temperature in Celsius: °C = (102 - 32) x 5/9 °C = 70 x 5/9 °C = 350/9 °C ≈ 38.9°C, which can be rounded to 39°C. 3. A body temperature of 39°C is considered to indicate a fever. Normal body temperature typically ranges from 36.1°C to 37.2°C, so a temperature of 39°C is higher than the normal range and suggests a fever. 4. Options A and B are incorrect as they do not reflect the conversion of 102°F to °C

5. Identify the type of error in the sentence "They went to the store, and bought groceries, then went home."

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The sentence combines two independent clauses without proper punctuation, forming a run-on sentence.

6. Which of the following is the main organ responsible for filtering urine?

• A. Kidneys
• B. Bladder
• C. Ureters
• D. Urethra

Correct answer: A

Rationale: Rationale: The kidneys are the main organs responsible for filtering urine. They play a crucial role in the urinary system by filtering waste products and excess substances from the blood to produce urine. The urine then travels from the kidneys to the bladder through the ureters, where it is stored until it is expelled from the body through the urethra. The bladder stores urine temporarily, while the ureters are tubes that transport urine from the kidneys to the bladder. The urethra is the tube through which urine is expelled from the body.
