1. After treatment, his PROGNOSIS was excellent. What does the term PROGNOSIS refer to?

• A. Compliance
• B. Range of motion
• C. Expected outcome
• D. Conclusion

Correct answer: C

Rationale: The term 'PROGNOSIS' refers to the expected outcome or likelihood of recovery after a specific treatment or illness. In this context, the word 'PROGNOSIS' directly relates to the expected outcome following the treatment, making choice C - Expected outcome - the correct answer. Choices A, B, and D are incorrect because 'Compliance' refers to following instructions, 'Range of motion' relates to the extent of movement in a joint, and 'Conclusion' is a summary or final decision, none of which captures the meaning of 'PROGNOSIS.'

2. What is the chemical reaction that involves breaking down a compound into component parts?

• A. Decomposition
• B. Synthesis
• C. Combustion
• D. Single replacement

Correct answer: A

Rationale: Decomposition is the correct answer because in a decomposition reaction, a compound is broken down into simpler substances. This type of reaction involves the splitting of a compound into its component parts, often through the use of heat, light, or electricity. Synthesis (choice B) is the opposite process where simpler substances are combined to form a more complex compound. Combustion (choice C) is a reaction involving rapid oxidation often accompanied by heat and light. Single replacement (choice D) is a reaction where one element replaces another in a compound.

3. What is the most important component of the cell, contributing to protection, communication, and the passage of substances?

• A. Cytoplasm
• B. Cell Membrane
• C. Cytoskeleton
• D. Vacuole

Correct answer: B

Rationale: The cell membrane is the correct answer. It is the most important component of the cell as it provides protection, facilitates communication, and regulates the passage of substances in and out of the cell. The cytoplasm (Choice A) is the gel-like substance within the cell that holds organelles, but it is not primarily responsible for the functions mentioned in the question. The cytoskeleton (Choice C) provides structural support to the cell but is not directly involved in protection, communication, or substance passage. Vacuoles (Choice D) are responsible for storage and maintaining turgor pressure but do not play a primary role in the functions specified in the question.

4. What form of radiation is composed of electrons traveling at around 16,000 km/sec?

• A. Alpha radiation
• B. Beta radiation
• C. Gamma radiation
• D. Delta radiation

Correct answer: B

Rationale: Beta radiation is composed of high-energy electrons (β- particles) or positrons (β+ particles) traveling at considerable speeds. In this case, the electrons traveling at around 16,000 km/sec align with the characteristics of beta radiation, making it the correct choice. Alpha radiation consists of helium nuclei, gamma radiation is electromagnetic radiation of high frequency, and delta radiation is not a recognized form of radiation, making them all incorrect choices.

5. What type of tissue is fat?

• A. Connective
• B. Muscle
• C. Nervous
• D. Epithelial

Correct answer: A

Rationale: Fat is a type of loose connective tissue known as adipose tissue. Adipose tissue primarily functions to store energy and provide cushioning and insulation for organs. While muscle tissue is responsible for movement, nervous tissue transmits nerve impulses, and epithelial tissue covers and protects body surfaces, fat specifically falls under the category of connective tissue.
