Biology
1. What is the main component of stomach acid?
- A. Hydrochloric acid
- B. Bicarbonate
- C. Bile salts
- D. Enzymes
Correct answer: A
Rationale: Rationale: Stomach acid, also known as gastric acid, is primarily composed of hydrochloric acid. Hydrochloric acid plays a crucial role in the digestive process by helping to break down food and kill bacteria in the stomach. Bicarbonate is a base that helps neutralize stomach acid in the small intestine. Bile salts are produced by the liver and stored in the gallbladder, aiding in the digestion and absorption of fats. Enzymes are proteins that help catalyze chemical reactions in the body, including the breakdown of food molecules during digestion.
2. 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.
3. The energy required to break a chemical bond is called:
- A. Kinetic energy
- B. Potential energy
- C. Activation energy
- D. Bond energy
Correct answer: C
Rationale: Rationale: Activation energy is the energy required to break a chemical bond and initiate a chemical reaction. Kinetic energy (option A) is the energy of motion, potential energy (option B) is stored energy, and bond energy (option D) is the energy required to break a particular chemical bond in a molecule. Among the options provided, activation energy best describes the energy required to break a chemical bond.
4. She reads about Path Goal theory. Which of the following behaviors is manifested by the
- A. Recognizes staff for going beyond expectations by giving them citations
- B. Challenges the staff to take individual accountability for their own practice
- C. Admonishes staff for being laggards.
- D. Reminds staff about the sanctions for non performance.
Correct answer: B
Rationale: The correct answer is B: 'Challenges the staff to take individual accountability for their own practice.' Path-Goal theory emphasizes the leader's role in motivating and guiding their team to achieve goals. This behavior aligns with the theory as it focuses on empowering employees to take ownership of their actions and responsibilities. By challenging staff to be individually accountable, the leader is providing clear direction and support, which can enhance motivation and performance within the team. Recognizing and rewarding staff for going beyond expectations (option A) would be more aligned with a transformational leadership style. Admonishing staff for being laggards (option C) and reminding staff about sanctions (option D) are not effective leadership behaviors according to the Path-Goal theory, as they do not focus on motivating and supporting employees to reach their goals.
5. Which state of matter has a definite shape and volume but can flow?
- A. Solid
- B. Liquid
- C. Gas
- D. Plasma
Correct answer: B
Rationale: Liquids have a definite volume but can take the shape of their container, unlike solids with fixed shapes and volumes.
6. Which additional information would be MOST relevant to the passage's argument?
- A. A detailed biography of a historical figure with no analysis of their impact on society.
- B. A timeline of technological advancements throughout history with no connection to social consequences.
- C. A case study of how historical knowledge informed the development of a successful solution to a contemporary problem.
- D. A statistical analysis of economic trends without any reference to historical events or context.
Correct answer: C
Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.
