Scientific Reasoning
1. A news article claims a scientist has discovered a cure for cancer. How should you approach this information?
- A. Celebrate the breakthrough and immediately share the news with everyone.
- B. Remain skeptical and wait for independent verification and further research.
- C. Dismiss the claim as impossible without any further investigation.
- D. Accept the information as fact because it was published in a news article.
Correct answer: B
Rationale: Extraordinary claims require extraordinary evidence. It's essential to wait for scientific consensus and verification before accepting such groundbreaking claims.
2. The concept of punctuated equilibrium suggests that:
- A. Evolution occurs gradually through the continuous accumulation of small changes over long periods.
- B. Evolution is characterized by long periods of relative stasis punctuated by rapid bursts of evolutionary change.
- C. The fossil record is a complete and accurate representation of all past life forms.
- D. Natural selection primarily favors extreme phenotypes within a population.
Correct answer: B
Rationale: Rationale: A) Evolution occurs gradually through the continuous accumulation of small changes over long periods - This statement describes the gradualism model of evolution, not punctuated equilibrium. Punctuated equilibrium suggests that evolution is characterized by long periods of little to no change (stasis) followed by relatively rapid bursts of evolutionary change. B) Evolution is characterized by long periods of relative stasis punctuated by rapid bursts of evolutionary change - This statement accurately describes the concept of punctuated equilibrium proposed by Stephen Jay Gould and Niles Eldredge. It suggests that species remain relatively unchanged for long periods of time, interrupted by sudden bursts of rapid evolution. C) The fossil record is a complete and accurate representation of all past life forms - This statement is incorrect as the fossil record is incomplete and biased towards certain types of organisms and environments. It does not provide a complete and accur
3. 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: A
Rationale: Acceleration is calculated as the change in velocity divided by the time taken.
4. Identify the bone with the greatest length in the human body.
- A. Femur (Thigh bone)
- B. Humerus (Upper arm bone)
- C. Tibia (Shin bone)
- D. Scapula (Shoulder blade)
Correct answer: A
Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.
5. Which form of energy is associated with the motion of an object?
- A. Kinetic energy
- B. Potential energy
- C. Thermal energy
- D. Electrical energy
Correct answer: a
Rationale: Kinetic energy is the energy of motion possessed by an object.
6. The involuntary "fight-or-flight" response is controlled by the:
- A. Sympathetic nervous system
- B. Parasympathetic nervous system
- C. Enteric nervous system
- D. Sensory nervous system
Correct answer: A
Rationale: The correct answer is A: Sympathetic nervous system. The "fight-or-flight" response is an automatic physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. This system prepares the body for action by increasing heart rate, dilating pupils, and redirecting blood flow to muscles. The parasympathetic nervous system, on the other hand, controls the body's "rest-and-digest" response, promoting relaxation and digestion. The enteric nervous system primarily regulates the gastrointestinal system, while the sensory nervous system is responsible for transmitting sensory information to the brain. Therefore, the sympathetic nervous system is specifically responsible for initiating the fight-or-flight response.
