A student sets up an investigation by placing a plastic bag over a plant. She secures the plastic bag so that it is completely sealed and nothing can enter. She observes the plant daily to see if it remains green and healthy.

Which TWO questions is this investigation, as described, designed to answer?

1. Does the plant require external factors such as air or water to remain green and healthy?

2. Can the plant survive solely based on the resources already within it without any external inputs?

The investigation, as described, is designed to answer the following two questions:

1. Does a sealed plastic bag affect the plant's ability to retain its green color?
2. Does a sealed plastic bag affect the plant's overall health and well-being?

The investigation, as described, is designed to answer the following two questions:

1. How does the plant's health and appearance change when it is completely sealed in a plastic bag?
2. Can a plant survive without any external factors, such as air or water, entering its environment?

To analyze these questions, the student sets up an experiment by completely sealing the plant in a plastic bag. By observing the plant daily, the student can note any changes in the plant's health and appearance. If the plant remains green and healthy despite being fully sealed, it would suggest that the plant can survive without external factors, such as air or water, entering its environment. Conversely, if the plant wilts or turns yellow/brown, it would indicate a negative impact due to the lack of essential elements entering the sealed environment.
