> 8. Describe the link between fire, seed germination and nitrogen dioxide gas.
Whispering bell seeds do not germinate unless exposed to nitrogen dioxide -- the same level of nitrogen dioxide that would be found in brush fire smoke.
> 9. How do Whispering bells that live in desert environments prepare seeds for germination?
The seeds get abraded as they are blown across the sand. Thus abraded, moisture can get to the seed to signal that it's time for germination.
> 10. Describe “terminator technology;” what it is and why it was developed
Terminator technology is used in genetically engineered crops so that they produce only sterile seeds. It was developed so that farmers could not save seeds from one year to plant them the next. This ensures that they will have to buy new seeds every year, thus ensuring a steady profit stream for the genetic engineering company that provides seeds that do grow.
