1. Which division of the nervous system is responsible for the "fight or flight" response, preparing the body to respond to stressful situations?

Correct answer: b

Rationale: The correct answer is B: Autonomic nervous system. The autonomic nervous system controls involuntary bodily functions, including the 'fight or flight' response. This response is crucial for survival, triggering the body to prepare for action in stressful situations by increasing heart rate, dilating pupils, and releasing adrenaline. The somatic nervous system (A) controls voluntary movements, the peripheral nervous system (C) connects the central nervous system to the rest of the body, and the central nervous system (D) consists of the brain and spinal cord, overseeing all bodily functions but not directly involved in the 'fight or flight' response.

2. Which of the following is a functional group commonly found in alcohols?

Correct answer: B

Rationale: The hydroxyl functional group (OH) is commonly found in alcohols. The other choices are associated with different functional groups.

3. How did life most likely arise on Earth?

Correct answer: A

Rationale: Rationale: The most widely accepted scientific theory for the origin of life on Earth is abiogenesis, which suggests that life arose from simple organic molecules in a primordial soup. This theory is supported by experiments such as the Miller-Urey experiment, which demonstrated that the basic building blocks of life could have formed under early Earth conditions. While there are other hypotheses and ongoing research in this field, the primordial soup theory is currently the most plausible explanation for the origin of life on Earth. The other options (B, C, and D) are not supported by scientific evidence or consensus.

4. You observe that plants in a greenhouse grow faster when exposed to red light compared to blue light. What is the next best step in your investigation?

Correct answer: D

Rationale: The next best step in the investigation would be to grow plants exposed to both red and blue light at equal intensities. This will help determine if the observed growth difference is due to the specific wavelength of light (red vs. blue) or if it is related to the intensity of light. By exposing plants to both red and blue light at equal intensities, you can compare their growth rates and determine if one wavelength has a greater effect on plant growth.

5. When ice melts, it undergoes a…

Correct answer: B

Rationale: Melting is a change in physical state, not a change in the chemical composition of the ice.

6. The phrase "green alternative" suggests that bioremediation is...

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.
