1. Long bones are one of the five major types of bones in the human body. All of the following bones are long bones, EXCEPT

• A. Thighs
• B. Forearms
• C. Ankles
• D. Fingers

Correct answer: D

Rationale: Long bones are one of the five major types of bones in the human body, characterized by their elongated shape. Thighs, forearms, and ankles are examples of long bones as they are longer than they are wide and have a tubular structure, aiding in support and movement. Fingers, however, are categorized as short bones due to their small size and shape. Short bones like fingers are essential for providing dexterity and precise movements rather than supporting weight or acting as levers for movement. Therefore, the correct answer is D, Fingers, as they are not classified as long bones.

2. If a scientist finds that the results of her experiment seem to contradict her hypothesis, what is the best course of action?

• A. Publish the results anyway, acknowledging that her hypothesis seems to have been incorrect.
• B. Keep trying the experiment until the results match her hypothesis.
• C. Publish the results, retroactively changing the hypothesis.
• D. None of the above; this cannot occur. The experimental results cannot contradict the hypothesis, by definition.

Correct answer: A

Rationale: The best course of action is to publish the results anyway, acknowledging that her hypothesis seems to have been incorrect. Science relies on accurate reporting and transparency, even if the results do not align with the original hypothesis. This allows for further discussion, analysis, and potentially new hypotheses to be developed based on the findings. It is essential in scientific research to report both positive and negative results to contribute to the body of knowledge and advance understanding in the field. Choice B is incorrect because persisting with the same experiment to force results to align with the hypothesis goes against scientific integrity and may lead to biased conclusions. Choice C is incorrect as changing the hypothesis after obtaining results is not scientifically sound and undermines the credibility of the research. Choice D is incorrect because science embraces the possibility of experimental results contradicting hypotheses, as this provides valuable insights for refining theories and expanding scientific knowledge.

3. Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

• A. frontal lobe
• B. occipital lobe
• C. parietal lobe
• D. temporal lobe

Correct answer: C

Rationale: The parietal lobe is the correct answer because it is primarily responsible for processing and integrating sensory information received from the rest of the body, including touch, pressure, temperature, and pain. This lobe plays a crucial role in spatial awareness, perception, and attention to sensory stimuli. It helps individuals make sense of the world around them and is essential for various sensory processes. The frontal lobe (choice A) is more associated with functions like reasoning, planning, and problem-solving. The occipital lobe (choice B) is responsible for processing visual information. The temporal lobe (choice D) is involved in functions like memory, auditory processing, and language comprehension, but it is not the primary lobe responsible for processing and integrating sensory information from the body.

4. Which of the following is a dense, interconnected mass of nerve cells located outside the central nervous system?

• A. ganglion
• B. dendrite
• C. cranial nerve
• D. pons

Correct answer: A

Rationale: A ganglion is a dense, interconnected mass of nerve cells located outside the central nervous system. Ganglia serve as relay points where nerve cells communicate and integrate signals. They are found along peripheral nerves, processing sensory information and coordinating motor responses. Choice B, dendrite, refers to a part of a neuron that receives signals, not a mass of nerve cells. Choice C, cranial nerve, is a bundle of nerves that emerge from the brain, not a mass of nerve cells. Choice D, pons, is a part of the brainstem, which is within the central nervous system, not located outside of it.

5. What is the formula to calculate acceleration?

• A. Acceleration = Mass/Force
• B. Acceleration = Force/Mass
• C. Acceleration = Time/Distance
• D. Acceleration = Time Change in Velocity

Correct answer: D

Rationale: Acceleration is defined as the rate of change of velocity with respect to time. The correct formula to calculate acceleration is Acceleration = Time Change in Velocity. This formula specifically represents how much an object's velocity changes over a specified time period, providing a measure of the object's speed change rate. Choices A and B are incorrect as they do not represent the relationship between acceleration and time change in velocity. Choice C is incorrect as it involves time and distance, which are not directly related to acceleration.
