1. What is the building block of RNA?
- A. Amino acid
- B. Nucleotide
- C. Protein
- D. Fatty acid
Correct answer: B
Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.
2. A car is traveling at a constant speed on a straight road. What is the net force acting on the car?
- A. A force equal to its weight pushing upwards
- B. A force equal to its weight pushing downwards
- C. A force equal to its engine power pushing forward
- D. No net force
Correct answer: D
Rationale: Since the car's speed is constant, there is no acceleration, and according to Newton's first law, a net force of zero is required.
3. In physics, what term describes the resistance of an object to changes in its motion?
- A. Inertia
- B. Momentum
- C. Gravity
- D. Kinetic energy
Correct answer: A
Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is described by Newton's First Law of Motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force that attracts objects towards each other, and kinetic energy (D) is the energy an object possesses due to its motion.
4. What is the difference between a phylum and a class?
- A. Phylums are broader and more general
- B. Classes are broader and more general
- C. They are synonyms, used for the same groups
- D. Phylums are for plants, classes are for animals
Correct answer: A
Rationale: Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. Phylum is a broader category that includes multiple classes within it. Phylum represents a group of organisms sharing a common body plan or evolutionary history, while a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phylums are broader and more general compared to classes.
5. She surfs the internet for more information about leadership styles. She reads about shared
- A. Leadership behavior is generally determined by the relationship between the leader’s
- B. Leaders believe that people are basically good and need not be closely controlled
- C. Leaders rely heavily on visioning and inspire members to achieve results
- D. Leadership is shared at the point of care.
Correct answer: B
Rationale: The correct answer is B because the statement 'Leaders believe that people are basically good and need not be closely controlled' aligns with the concept of shared leadership. Shared leadership involves distributing leadership responsibilities and authority among team members based on the belief that everyone has valuable contributions to make. This approach fosters a sense of trust and empowerment within the team, allowing individuals to take initiative and collaborate effectively. In contrast, option A refers to leadership behavior being determined by the relationship between the leader and followers, which is not directly related to the concept of shared leadership. Option C emphasizes visioning and inspiration, which are important aspects of leadership but do not specifically address the shared nature of leadership. Option D mentions leadership being shared at the point of care, which is too specific and does not encompass the broader concept of shared leadership.
6. 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.
