1. She notes that there is an increasing unrest of the staff due to fatigue brought about by
- A. Evaluate the overall result of the unrest
- B. Initiate a group interaction
- C. Develop a plan and implement it
- D. Identify external and internal forces.
Correct answer: C
Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.
2. What is the scientific term for the involuntary rhythmic contraction and relaxation of the heart muscle?
- A. Peristalsis
- B. Myogenesis
- C. Myocardial contractility
- D. Systole and diastole
Correct answer: D
Rationale: The correct answer is D: Systole and diastole. Systole refers to the phase of the heartbeat when the heart muscle contracts and pumps blood out, while diastole is the phase when the heart muscle relaxes and fills with blood. This rhythmic contraction and relaxation of the heart muscle is crucial for maintaining blood circulation throughout the body. Peristalsis (option A) is the involuntary constriction and relaxation of the muscles of the gastrointestinal tract that pushes contents forward. Myogenesis (option B) is the formation of muscle tissue. Myocardial contractility (option C) refers to the ability of the heart muscle to contract. Therefore, the most appropriate term for the described process is systole and diastole.
3. What are the building blocks of proteins?
- A. Sugars
- B. Fatty acids
- C. Amino acids
- D. Nucleotides
Correct answer: C
Rationale: Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (A) are the building blocks of carbohydrates, fatty acids (B) are the building blocks of lipids, and nucleotides (D) are the building blocks of nucleic acids like DNA and RNA.
4. A syringe holds 3ml of liquid. How many syringes are needed to measure 15ml of liquid?
- A. 3
- B. 5
- C. 7
- D. 9
Correct answer: B
Rationale: Divide the total liquid volume (15ml) by the syringe capacity (3ml/syringe) to get 5 syringes.
5. The main purpose of using strong vocabulary in your writing is to:
- A. Impress the reader with your knowledge of complex words.
- B. Confuse the reader and make them think harder.
- C. Communicate your ideas clearly and precisely.
- D. Shorten your sentences and save space.
Correct answer: C
Rationale: While using complex vocabulary can showcase knowledge, the primary goal is to ensure the reader understands your message. Precise words eliminate confusion and ambiguity.
6. Which of the following is NOT a greenhouse gas?
- A. Carbon dioxide
- B. Water vapor
- C. Nitrogen
- D. Methane
Correct answer: C
Rationale: Rationale: A) Carbon dioxide: Carbon dioxide is a greenhouse gas that is naturally present in the Earth's atmosphere and is also released through human activities such as burning fossil fuels. B) Water vapor: Water vapor is a greenhouse gas that is naturally present in the atmosphere and plays a significant role in the Earth's climate system. C) Nitrogen: Nitrogen is not considered a greenhouse gas because it does not have the ability to absorb and emit infrared radiation in the same way that greenhouse gases like carbon dioxide and methane do. D) Methane: Methane is a potent greenhouse gas that is released through natural processes such as wetland decomposition and human activities such as livestock farming and fossil fuel extraction. Therefore, the correct answer is C) Nitrogen, as it is not a greenhouse gas.
