physics
1. Define the term "velocity" in relation to motion.
- A. Speed in a specific direction
- B. Distance traveled in a given time
- C. Rate of change of position
- D. Acceleration due to gravity
Correct answer:
Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.
2. Which property describes a substance's resistance to flow?
- A. Density
- B. Viscosity
- C. Conductivity
- D. Reactivity
Correct answer: b
Rationale: Viscosity refers to a substance's resistance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.
3. Differentiate between genotype and phenotype in the context of gene expression.
- A. Genotype refers to the physical manifestation of a trait, while phenotype represents its underlying genetic makeup.
- B. Genotype encompasses the spectrum of possible traits encoded by an organism's genes, while phenotype signifies the specific trait observed.
- C. Genotype denotes the presence of dominant alleles, while phenotype reflects the influence of recessive alleles.
- D. There is no distinction; both terms are interchangeable.
Correct answer: B
Rationale: Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses. - Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment. - While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits. - Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.
4. What is the function of introns in eukaryotic genes?
- A. They code for protein sequences.
- B. They are involved in gene regulation.
- C. They are removed during mRNA processing.
- D. They are non-functional remnants of ancient DNA.
Correct answer: C
Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.
5. The phrase "a bold new world" is an example of
- A. Hyperbole
- B. Oxymoron
- C. Simile
- D. Metaphor
Correct answer: B
Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.
6. Aubrey thinks about primary nursing as a system to deliver care. Which of the following
- A. Collaborates with the physician
- B. Provides care to a group of patients together with a group of nurses
- C. Provides care for 5-6 patients during their hospital stay.
- D. Performs comprehensive initial assessment
Correct answer: D
Rationale: Primary nursing is a care delivery system where one nurse is responsible for the total nursing care needs of a group of patients throughout their hospital stay. This includes performing comprehensive initial assessments, developing care plans, coordinating with other healthcare team members, and providing direct patient care. Option D is the correct answer as it aligns with the core principles of primary nursing, emphasizing the nurse's role in conducting thorough assessments to ensure individualized and holistic care for each patient in their caseload. Options A, B, and C do not accurately reflect the key components of primary nursing, making them incorrect choices.
