Anatomy
1. Skeletal muscles are attached to bones by tough connective tissues called
- A. Ligaments
- B. Tendons
- C. Cartilage
- D. Fascia
Correct answer: B
Rationale: The correct answer is B: Tendons. Skeletal muscles are connected to bones by tendons, which are tough connective tissues that transmit the force generated by the muscle to the bone, allowing movement. Ligaments (A) connect bone to bone and provide stability to joints. Cartilage (C) is a smooth, firm tissue that covers the surface of bones at joints, reducing friction and absorbing shock. Fascia (D) is a connective tissue that surrounds muscles and other structures, providing support and protection.
2. Which additional information would be MOST relevant to the passage's argument?
- A. A detailed biography of a historical figure with no analysis of their impact on society.
- B. A timeline of technological advancements throughout history with no connection to social consequences.
- C. A case study of how historical knowledge informed the development of a successful solution to a contemporary problem.
- D. A statistical analysis of economic trends without any reference to historical events or context.
Correct answer: C
Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.
3. Which word is spelled correctly?
- A. Accomodate
- B. Acquiesce
- C. Percieve
- D. Dilema
Correct answer: B
Rationale: Option B is the correct spelling for "to submit or agree without protest."
4. Harry is a Unit Manager I the Medical Unit. He is not satisfied with the way things are going
- A. Call for a staff meeting and take this up in the agenda.
- B. Seek help from her manager.
- C. Develop a strategic action on how to deal with these concerns.
- D. Ignore the issues since these will be resolved naturally.
Correct answer: A
Rationale: Choosing option A, 'Call for a staff meeting and take this up in the agenda,' is the best course of action for Harry as a Unit Manager. By calling for a staff meeting, Harry can openly address his concerns with the team, gather input from team members, and work collaboratively to find solutions. This approach promotes transparency, communication, and teamwork, which are essential in resolving issues within a unit. Seeking help from his manager, as suggested in option B, may be necessary in some cases, but initiating a discussion with the staff first allows for a more inclusive problem-solving process. Developing a strategic action, as in option C, is important, but involving the team in this process through a staff meeting is crucial for buy-in and implementation. Ignoring the issues, as in option D, is never a productive approach as unresolved issues can escalate and impact team morale and performance. Therefore, option A is the most effective and proactive way for Harry to address hi
5. The adaptive immune system has two main branches: humoral and cell-mediated immunity. Which type of immune cell is primarily responsible for antibody production?
- A. Helper T cells
- B. Cytotoxic T cells
- C. B cells
- D. Natural killer cells
Correct answer: C
Rationale: The correct answer is C: B cells. B cells are a type of lymphocyte that plays a central role in humoral immunity by producing antibodies. When activated by antigens, B cells differentiate into plasma cells, which are responsible for producing and secreting antibodies. Helper T cells (option A) primarily assist in activating B cells and other immune cells. Cytotoxic T cells (option B) are involved in cell-mediated immunity, where they directly kill infected cells. Natural killer cells (option D) are part of the innate immune system and target virus-infected and cancerous cells. Therefore, B cells are the immune cells primarily responsible for antibody production in the adaptive immune system.
6. The Hardy-Weinberg equilibrium describes a population that is:
- A. Undergoing rapid evolution due to strong directional selection.
- B. Not evolving and at genetic equilibrium with stable allele frequencies.
- C. Experiencing a founder effect leading to a reduction in genetic diversity.
- D. Dominated by a single homozygous genotype that eliminates all variation.
Correct answer: B
Rationale: Rationale: The Hardy-Weinberg equilibrium describes a theoretical population in which allele frequencies remain constant from generation to generation, indicating that the population is not evolving. This equilibrium occurs under specific conditions: no mutation, no gene flow, random mating, a large population size, and no natural selection. In this scenario, all genotypes are in proportion to the allele frequencies, and genetic diversity is maintained. Options A, C, and D do not accurately describe a population in Hardy-Weinberg equilibrium. Option A suggests rapid evolution due to strong directional selection, which would disrupt the equilibrium. Option C mentions a founder effect, which can reduce genetic diversity but is not a characteristic of a population in Hardy-Weinberg equilibrium. Option D describes a population dominated by a single homozygous genotype, which also does not align with the genetic diversity seen in a population at Hardy-Weinberg equilibrium.
