1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?
- A. Anemia
- B. Edema
- C. Hypertension
- D. Diabetes
Correct answer: B
Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.
2. Which macromolecule serves as the repository of genetic information in all living organisms?
- A. Ribonucleic acid (RNA)
- B. Deoxyribonucleic acid (DNA)
- C. Protein
- D. Carbohydrate
Correct answer: B
Rationale: - DNA is the macromolecule that serves as the repository of genetic information in all living organisms. It carries the genetic instructions necessary for the growth, development, functioning, and reproduction of organisms. - RNA (option A) is involved in various cellular processes, including protein synthesis, but DNA is the primary molecule responsible for storing genetic information. - Proteins (option C) are essential for various cellular functions but do not serve as the primary repository of genetic information. - Carbohydrates (option D) are important for energy storage and structural support but do not store genetic information.
3. Which of these organisms belongs to the kingdom Protista?
- A. Coral
- B. Yeast
- C. Euglena
- D. Mushroom
Correct answer: C
Rationale: A) Coral belongs to the kingdom Animalia, specifically in the phylum Cnidaria. B) Yeast belongs to the kingdom Fungi. C) Euglena is a unicellular organism that belongs to the kingdom Protista. It is a type of protist that has characteristics of both plants and animals. D) Mushroom belongs to the kingdom Fungi. Therefore, among the options provided, only Euglena belongs to the kingdom Protista.
4. Which of the following is NOT a function of the integumentary system?
- A. Regulation of body temperature
- B. Protection from pathogens
- C. Synthesis of vitamin D
- D. Production of digestive enzymes
Correct answer: D
Rationale: The correct answer is D. The production of digestive enzymes is not a function of the integumentary system. The integumentary system is responsible for regulating body temperature, protecting the body from pathogens, and synthesizing vitamin D. Digestive enzymes are produced by organs in the digestive system, such as the pancreas and stomach, and not by the integumentary system.
5. Which deadly disease was eliminated through an intensive vaccination program?
- A. AIDS
- B. Smallpox
- C. Diabetes type 1
- D. Rheumatoid arthritis
Correct answer: B
Rationale: Smallpox was eradicated globally through an intensive vaccination program. The World Health Organization (WHO) led a successful global campaign to vaccinate people against smallpox, ultimately leading to its eradication in 1980. AIDS, diabetes type 1, and rheumatoid arthritis are serious conditions, but they were not eliminated through vaccination programs like smallpox. Therefore, the correct answer is B, Smallpox. AIDS is caused by the human immunodeficiency virus (HIV) and remains a significant global health issue. Diabetes type 1 is an autoimmune condition where the body attacks insulin-producing cells, leading to high blood sugar levels. Rheumatoid arthritis is an autoimmune condition that primarily affects the joints, causing inflammation and pain.
