1. What is the relationship between work and energy?
- A. Work is the rate of energy transfer
- B. Work and energy are the same concepts
- C. Work is the result of energy
- D. Work changes an object's energy from one form to another
Correct answer: d
Rationale: Work is the process that changes an object's energy from one form to another or transfers it from one object to another.
2. What is the product of the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH)?
- A. NaCl + H2O
- B. NaOH + HCl
- C. Na2Cl + H2O
- D. NaClO3 + H2
Correct answer: a
Rationale: The reaction between HCl and NaOH results in the formation of sodium chloride (NaCl) and water (H2O).
3. Which of the following is an example of an aromatic hydrocarbon?
- A. Ethane
- B. Benzene
- C. Propane
- D. Butene
Correct answer: B
Rationale: Benzene is an example of an aromatic hydrocarbon. The other choices are aliphatic hydrocarbons.
4. Which blood type is a universal donor?
- A. A
- B. B
- C. AB
- D. O
Correct answer: D
Rationale: Rationale: Blood type O is considered the universal donor because individuals with type O blood can donate red blood cells to individuals with any ABO blood type (A, B, AB, or O) without causing an adverse reaction. This is because type O blood lacks A or B antigens on the surface of red blood cells, which helps minimize the risk of an immune response when transfused into individuals with different blood types. Therefore, type O blood is in high demand for blood transfusions in emergency situations when the recipient's blood type is unknown or when there is a shortage of specific blood types.
5. The element responsible for the green color of leaves is:
- A. Magnesium
- B. Iron
- C. Copper
- D. Zinc
Correct answer: A
Rationale: Magnesium is the central element of chlorophyll, the pigment responsible for photosynthesis
6. Differentiate between epithelial and connective tissue.
- A. Epithelial tissue is exclusively found in the lungs, while connective tissue supports tendons.
- B. Both are composed of cells, but epithelial tissue lines surfaces and glands, while connective tissue binds other tissues.
- C. Epithelial tissue is more vascularized, while connective tissue is responsible for muscle contraction.
- D. Epithelial tissue is the largest tissue type, while connective tissue is the smallest.
Correct answer: B
Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.
