Anatomy
1. What is the scientific term for scar tissue?
- A. Epithelial tissue
- B. Fibrous connective tissue
- C. Cartilage
- D. Adipose tissue
Correct answer: B
Rationale: The correct answer is B: Fibrous connective tissue. Scar tissue is formed during the process of wound healing, where fibroblasts produce collagen fibers to repair damaged tissue. This results in the formation of fibrous connective tissue, which is different from epithelial tissue (A), cartilage (C), and adipose tissue (D). While epithelial tissue lines surfaces and organs, cartilage is a type of connective tissue found in joints, and adipose tissue is a type of connective tissue that stores energy in the form of fat. Scar tissue, on the other hand, is primarily composed of collagen fibers and is classified as fibrous connective tissue.
2. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?
- A. It is the only viable solution to the problem and should be prioritized.
- B. It is a promising approach but requires further research and development.
- C. It is less effective than traditional methods and poses environmental risks.
- D. It is irrelevant to the problem and will not make a significant impact.
Correct answer: B
Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.
3. Which of the following is a unit of measurement for energy?
- A. Watt (W)
- B. Joule (J)
- C. Newton (N)
- D. Kilogram (kg)
Correct answer: b
Rationale: Energy is measured in Joules (J) in the SI unit system.
4. Which type of muscle is characterized by involuntary contractions, is striated, and is primarily found in the heart?
- A. Skeletal muscle
- B. Smooth muscle
- C. Cardiac muscle
- D. Elastic muscle
Correct answer: C
Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by involuntary contractions, meaning it contracts without conscious control. It is striated, which refers to the striped appearance of muscle fibers under a microscope. Cardiac muscle is primarily found in the heart, where it plays a crucial role in pumping blood throughout the body. Skeletal muscle (option A) is also striated but is under voluntary control. Smooth muscle (option B) is non-striated and found in organs like the intestines. Elastic muscle (option D) is not a recognized type of muscle tissue.
5. Which of the following is NOT typically found in healthy urine?
- A. Urea
- B. Glucose
- C. Creatinine
- D. Electrolytes
Correct answer: B
Rationale: Glucose is NOT typically found in healthy urine because the kidneys filter glucose from the blood, and any excess is excreted in the urine. In healthy individuals, the renal threshold for glucose reabsorption is low, so glucose should not be present in significant amounts in urine. On the other hand, urea, creatinine, and electrolytes are all normal components of urine. Urea is a waste product of protein metabolism, creatinine is a waste product of muscle metabolism, and electrolytes like sodium and potassium are essential for various bodily functions and are excreted in urine. Therefore, option B is the correct answer as glucose is not typically found in healthy urine.
6. A bar graph shows the number of patients admitted to the ER each day for a week. How do you determine the day with the highest number of admissions?
- A. Find the tallest bar in the graph.
- B. Compare the heights of all bars.
- C. Calculate the average number of admissions per day.
- D. Subtract the lowest number of admissions from the highest.
Correct answer: A
Rationale: The best approach is to find the tallest bar
