Chemistry
1. What is the atomic number of an element?
- A. The number of protons in an atom's nucleus.
- B. The number of neutrons in an atom's nucleus.
- C. The number of electrons in an atom's valence shell.
- D. The number of isotopes of an element.
Correct answer: B
Rationale: The atomic number of an element is a fundamental property that defines the identity of an element. It is the number of protons in the nucleus of an atom. The number of protons determines the element's position in the periodic table and its chemical properties.
2. Energy for most cellular processes is produced in the:
- A. Nucleus
- B. Cytoplasm
- C. Mitochondria
- D. Ribosomes
Correct answer: C
Rationale: The correct answer is C: 'Mitochondria.' The mitochondria are known as the powerhouse of the cell, where the process of cellular respiration takes place to produce energy in the form of ATP. The nucleus (option A) houses the cell's genetic material but is not directly involved in energy production. The cytoplasm (option B) is a jelly-like substance that surrounds organelles but is not the primary site of energy production. Ribosomes (option D) are involved in protein synthesis, not energy production. Therefore, the mitochondria play a crucial role in generating energy for most cellular processes.
3. A news article claims a scientist has discovered a single, universal cure for all allergies. This claim seems:
- A. Entirely plausible and should be immediately accepted.
- B. Unlikely and warrants further investigation and verification.
- C. Impossible because allergies have diverse causes.
- D. Irrelevant as long as it can help some people alleviate suffering.
Correct answer: B
Rationale: Science rarely offers universal solutions for complex biological phenomena. Extraordinary claims require extraordinary evidence and independent verification.
4. Identify the appositive in the following sentence: "My favorite author, Agatha Christie, wrote many detective novels."
- A. favorite
- B. Agatha Christie
- C. many
- D. novels
Correct answer: B
Rationale: An appositive renames or clarifies the noun or pronoun preceding it.
5. Maintaining good muscle strength and flexibility as we age becomes important to avoid:
- A. Headaches
- B. Falls
- C. Anxiety
- D. Common cold
Correct answer: B
Rationale: The correct answer is B: 'Falls.' Maintaining good muscle strength and flexibility as we age is crucial for preventing falls, which become more common with age and can lead to serious injuries such as fractures. Strong muscles and good flexibility help in maintaining balance and stability, reducing the risk of falls. Headaches, anxiety, and the common cold are not directly related to muscle strength and flexibility, making them less likely to be avoided by focusing on these aspects of physical health.
6. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in
- A. Vision
- B. Goal
- C. Philosophy
- D. Mission
Correct answer: A
Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.
