8. Why does one variation of moths have a greater survivability rate than another variation of moths?
Part ONE:
1. Click set up.
2. Make sure the parameters are set as follows:
cycle pollution = on
total moths = 100
pollution = 0%
ticks = slower
3. Click on “go” button.
4. Click “go” button a second time at 25 ticks to stop the simulation.
5. Repeat for 50 ticks, 75 ticks, 100 ticks, 125 ticks, and 150 ticks. Record observations.
