1. What is the term for the shedding of the outermost layer of the epidermis?
- A. Desquamation
- B. Exfoliation
- C. Keratinization
- D. Epidermolysis
Correct answer: A
Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.
2. Frequent, painful urination is a common symptom of:
- A. Diabetes
- B. Urinary tract infection (UTI)
- C. Kidney stones
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, 'All of the above.' Frequent, painful urination can be a symptom of various conditions affecting the urinary system. In diabetes, high blood sugar levels can lead to increased urine production. UTIs often cause painful urination due to the infection in the urinary tract. Kidney stones can also result in frequent and painful urination as they obstruct the flow of urine. Therefore, all three options can present with the common symptom of frequent, painful urination, making 'All of the above' the correct choice.
3. Which orbital can hold a maximum of 8 electrons?
- A. s orbital
- B. p orbital
- C. d orbital
- D. f orbital
Correct answer: C
Rationale: d orbital - Each d orbital can hold a maximum of 2 electrons, and there are 5 d orbitals, totaling 10 possible electrons.
4. You need to repaint a cylindrical water tank with a diameter of 2 meters and a height of 3 meters. Assuming one can of paint covers 10 sq m, how many cans do you need (consider only the exterior surface)?
- A. 6 cans
- B. 9 cans
- C. 12 cans
- D. 15 cans
Correct answer: C
Rationale: Calculate the surface area of the cylinder and divide by the coverage area per can.
5. The deeper layer of the skin, containing connective tissue, blood vessels, and nerve endings, is called the:
- A. Epidermis
- B. Dermis
- C. Hypodermis
- D. Stratum corneum
Correct answer: B
Rationale: The correct answer is B: Dermis. The dermis is the deeper layer of the skin that contains important structures such as connective tissue, blood vessels, and nerve endings. It plays a crucial role in providing support and nourishment to the epidermis, the outermost layer of the skin. The epidermis, option A, is actually the outermost layer responsible for protecting the body from environmental factors. The hypodermis, option C, is the deepest layer of the skin that primarily consists of fat and connective tissue. Stratum corneum, option D, is the outermost layer of the epidermis composed of dead skin cells. Therefore, the dermis is the correct answer in this case.
6. A scientific theory is:
- A. A personal belief or hunch about how something works.
- B. A well-substantiated explanation based on evidence and repeated testing.
- C. A single experiment's findings not yet confirmed by others.
- D. A fixed and unchanging dogma beyond questioning.
Correct answer: B
Rationale: Theories in science are constantly evolving and open to revision as new data emerges, unlike personal beliefs or fixed dogmas.
