1. What property of matter remains constant regardless of changes in its state?
- A. Mass
- B. Volume
- C. Density
- D. Weight
Correct answer: a
Rationale: Mass remains constant for a given amount of matter, regardless of its state (solid, liquid, or gas) or its location in the universe. Explanation of other options:
2. Approximately how many muscles are there in the human body?
- A. 100
- B. 100
- C. 600
- D. Over 600
Correct answer: D
Rationale: The correct answer is D. There are over 600 muscles in the human body. Muscles are responsible for movement, posture, and generating heat in the body. The exact number of muscles can vary slightly from person to person, but it is generally accepted that there are over 600 muscles in the human body. These muscles work together to allow us to perform various movements and activities throughout our daily lives.
3. Which of the following is a common characteristic of alkynes?
- A. They have a triple bond between carbon atoms.
- B. They are saturated hydrocarbons.
- C. They contain only single bonds.
- D. They are aromatic compounds.
Correct answer: A
Rationale: Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms. This triple bond is a distinctive feature of alkynes, distinguishing them from alkanes (which contain only single bonds) and alkenes (which contain at least one double bond). Alkynes are unsaturated hydrocarbons due to the presence of the triple bond. Aromatic compounds, on the other hand, have a specific cyclic structure with resonance stabilization, which is not a characteristic of alkynes.
4. A new invention claims to solve the energy crisis. What criteria should you use to evaluate this claim?
- A. The inventor's qualifications and credentials.
- B. The technology's cost-effectiveness and affordability.
- C. Evidence of independent testing and scientific validation.
- D. Testimonials from celebrities and public figures.
Correct answer: C
Rationale: When evaluating a claim about solving the energy crisis, it is crucial to look for evidence of independent testing and scientific validation. This ensures that the technology has been rigorously assessed and verified by experts in the field, providing credibility to the invention's effectiveness. Testimonials from celebrities and public figures (option D) may not provide reliable information about the technology's actual capabilities. The inventor's qualifications and credentials (option A) are important but do not guarantee the technology's success. Cost-effectiveness and affordability (option B) are significant factors but should be considered alongside scientific validation to assess the overall impact and feasibility of the invention.
5. The student studies diligently for her upcoming exam. Which word is the plural form of "study"?
- A. studies
- B. studying
- C. studied
- D. studier
Correct answer: C
Rationale: The plural form of a noun refers to more than one of that thing.
6. What is the function of the Golgi apparatus?
- A. Breaking down and recycling cellular waste
- B. Packaging and transporting proteins and lipids
- C. Generating energy through cellular respiration
- D. Translating DNA into proteins
Correct answer: B
Rationale: The correct answer is B: Packaging and transporting proteins and lipids. The Golgi apparatus plays a crucial role in processing, packaging, and distributing proteins and lipids synthesized by the cell. It modifies these molecules and directs them to their appropriate destinations within the cell or for secretion outside the cell. This function is essential for maintaining the proper functioning of the cell and coordinating various cellular processes. Options A, C, and D are incorrect as they describe functions carried out by other cellular organelles, highlighting the specificity and importance of the Golgi apparatus in protein and lipid trafficking.
