Biology

1. What is the scientific term for the study of genes and their role in disease?

Correct answer: D

Rationale: Rationale: A) Molecular biology primarily focuses on the study of biological processes at a molecular level, including the structure and function of molecules essential to life such as DNA, RNA, and proteins. While molecular biology may involve the study of genes, it is not specifically focused on their role in disease. B) Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. While biochemistry may involve the study of genetic material, it does not specifically focus on the role of genes in disease. C) Evolutionary biology is the study of the processes that have shaped the diversity of life on Earth over time, including how species evolve and adapt to their environments. While genetics plays a role in evolutionary biology, it is not the primary focus of this field. D) Genomic medicine is the scientific term for the study of genes and their role in disease. This field involves understanding how variations in an indi

2. A routine urinalysis is a common diagnostic test. What does a urinalysis typically evaluate?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' A routine urinalysis is a comprehensive test that evaluates various aspects of urine to provide insights into overall health. Blood sugar levels can be assessed to screen for diabetes or monitor diabetes management. The presence of white blood cells in the urine can indicate a possible infection in the urinary tract. Additionally, kidney function can be evaluated by examining factors such as protein levels, creatinine, and electrolytes in the urine. Therefore, a urinalysis typically evaluates blood sugar levels, presence of white blood cells (indicating possible infection), and kidney function, making 'All of the above' the correct choice.

3. What happens to the frequency of a wave when its wavelength is doubled, assuming the speed remains constant?

Correct answer: C

Rationale: Since the wave speed is constant, if the wavelength increases, the frequency must decrease to maintain the same energy transfer per unit time.

4. A car brakes to a stop on a level road. Which of the following forces does NOT do work on the car?

Correct answer: B

Rationale: While the other forces do work by changing the car's motion or energy, the normal force acts perpendicular to the motion and doesn't contribute to the car's stopping.

5. She decides to illustrate the organizational structure. Which of the following elements is

Correct answer: D

Rationale: The correct answer is D, 'Unity of direction.' In the context of illustrating organizational structure, unity of direction refers to the concept that activities within an organization should be directed towards a common goal. It ensures that all efforts are aligned and coordinated towards achieving the organization's objectives. This element helps in avoiding conflicts and confusion by providing clarity and focus on the overall mission of the organization, which is essential for effective organizational performance. Level of authority, lines of communication, and span of control are important elements in organizational structure as well, but in this scenario, unity of direction specifically pertains to the coordination and alignment of activities towards a common purpose.

6. Which of the following is a MAJOR consequence of a stroke?

Correct answer: C

Rationale: The correct answer is C: 'Brain damage due to interrupted blood flow.' A stroke occurs when there is a sudden interruption in the blood supply to the brain, leading to brain damage. This interruption can result in various consequences such as paralysis, speech and vision problems, cognitive impairments, and in severe cases, even death. Other options like 'Irregular heart rhythm' (A) and 'Chronic fatigue and muscle weakness' (D) can be associated with health conditions but are not direct consequences of a stroke. 'Rapid weight gain or loss' (B) is typically not a major consequence of a stroke compared to the significant impact of brain damage.
