1. Which word best synonyms with the word 'elated'?

• A. Angry
• B. Sad
• C. Excited
• D. Confused

Correct answer: C

Rationale: The word 'elated' means extremely happy and joyful. 'Excited' is the best synonym as it also conveys feelings of happiness and enthusiasm, similar to 'elated'. On the other hand, 'angry', 'sad', and 'confused' represent different emotions that are not synonymous with 'elated'. Choosing 'angry' indicates a strong negative emotion, 'sad' represents a feeling of sorrow, and 'confused' implies a state of being unclear or uncertain, which are all contrary to the meaning of 'elated'. Therefore, 'Excited' is the correct choice in this context.

2. Pernell received the following scores on five exams: 81, 92, 87, 89, and 94. What is the approximate average of these scores?

• A. 81
• B. 84
• C. 89
• D. 91

Correct answer: C

Rationale: To calculate the average of Pernell's scores, add all the scores together and then divide by the number of scores. (81 + 92 + 87 + 89 + 94) = 443. Now, divide 443 by 5: 443 ÷ 5 = 89, which is the average score.

3. Which of the following is a dense, interconnected mass of nerve cells located outside the central nervous system?

• A. ganglion
• B. dendrite
• C. cranial nerve
• D. pons

Correct answer: A

Rationale: A ganglion is a dense, interconnected mass of nerve cells located outside the central nervous system. Ganglia serve as relay points where nerve cells communicate and integrate signals. They are found along peripheral nerves, processing sensory information and coordinating motor responses. Choice B, dendrite, refers to a part of a neuron that receives signals, not a mass of nerve cells. Choice C, cranial nerve, is a bundle of nerves that emerge from the brain, not a mass of nerve cells. Choice D, pons, is a part of the brainstem, which is within the central nervous system, not located outside of it.

4. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. While the Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does. Therefore, the correct answer is the nucleus.

5. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).
