This chart shows the experimental design of four students who are all observing what kind of bird seed birds tend to eat more often.
Student 1
- Performed the experiment once
- Used the same area, same time of day, and same amount of seeds
Student 2
- Repeated the experiment 5 times
- Used the same area, different time of day, and different amount of seeds
Student 3
- Repeated the experiment 2 times
- Used the same area, different time of day, and different amount of seeds
Student 4
- Repeated the experiment 5 times
- Used the same area, same time of day, and same amount of seeds
Which student is the most likely to have reproducible results?
Student 1
Student 2
Student 3
Student 4

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
