Chemistry
1. Which of the following functional groups has the highest priority according to the Cahn-Ingold-Prelog (CIP) ranking system?
- A. Alcohol (OH)
- B. Aldehyde (CHO)
- C. Carboxylic Acid (COOH)
- D. Amine (NH2)
Correct answer: C
Rationale: According to the Cahn-Ingold-Prelog (CIP) ranking system, the priority of functional groups is determined based on the atomic number of the atoms directly bonded to the functional group. In this case, carboxylic acid (COOH) has the highest priority because the carbon atom is directly bonded to two oxygen atoms, which have higher atomic numbers than carbon. The alcohol (OH) group has a lower priority as the oxygen atom is only bonded to hydrogen, while the aldehyde (CHO) and amine (NH2) groups have lower priorities compared to carboxylic acid. Therefore, option C, carboxylic acid, is the correct answer as it has the highest priority in the CIP ranking system.
2. What is the process by which decomposers break down organic matter?
- A. Photosynthesis
- B. Bioremediation
- C. Decomposition
- D. Nitrification
Correct answer: C
Rationale: Rationale: A) Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy to produce glucose from carbon dioxide and water. This process is not related to the breakdown of organic matter by decomposers. B) Bioremediation is the use of living organisms to clean up contaminated environments. While it involves the use of microorganisms to break down pollutants, it is not specifically focused on breaking down organic matter. C) Decomposition is the process by which decomposers such as bacteria, fungi, and other organisms break down organic matter into simpler substances. This process is essential for nutrient recycling in ecosystems. D) Nitrification is the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of nitrite to nitrate by nitrifying bacteria. This process is part of the nitrogen cycle and is not directly related to the breakdown of organic matter.
3. The transfer of energy through feeding relationships in an ecosystem is called a:
- A. Food Chain
- B. Food Web
- C. Habitat
- D. Biome
Correct answer: A
Rationale: Rationale: A food chain is a linear sequence of organisms where each organism consumes the one below it and is consumed by the one above it. This transfer of energy through feeding relationships is a fundamental concept in ecology to understand how energy flows through an ecosystem. In a food chain, energy is transferred from producers (plants) to primary consumers (herbivores), then to secondary consumers (carnivores), and so on. Each step in the food chain represents a trophic level, and energy is lost as heat at each level, resulting in a pyramid-shaped energy flow. Food webs, on the other hand, represent a more complex network of interconnected food chains within an ecosystem. Habitats refer to the specific environment where an organism lives, and biomes are large geographical areas characterized by specific climate and vegetation types.
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. The process of mixing two or more substances to form a heterogeneous mixture is called:
- A. Dissolving
- B. Diluting
- C. Mixing
- D. Reacting
Correct answer: C
Rationale: Mixing results in a heterogeneous mixture where the components are physically distinguishable, unlike solutions where everything dissolves uniformly
6. Acknowledge the organ devoted to blood filtration.
- A. Liver
- B. Kidneys
- C. Spleen
- D. Pancreas
Correct answer: B
Rationale: The kidneys are the primary organs responsible for filtering blood and removing waste products, excess fluids, and toxins. They play a crucial role in maintaining the body's internal environment and regulating blood pressure.
