A student used the low-power objective a microscope and observed cell as shown in the diagram below. When he switched to high power, the cell was no longer visible. This most likely happened because switching to high power made the
1. field too bright to see the organism
2. image too small to be seen
3. area of the slide being viewed smaller
4. fine-adjustment knob no longer functional

1. genetic engineering
2. asexual reproduction
4. gamete formation
3. selective breeding
Researchers at a university discovered a substance that was effective in preventing a flu like illness. They repeated their experiment several times and noted the results. What is the main reason why scientists repeat their experiments?
