Answer:
Events which occur in chemical reactions like photosynthesis are extremely fast.
Explanation:
To see what happens in reactions such as photosynthesis, scientists need advanced cameras that can capture ultra-fast motions occurring within extremely short scales of time.
To promote the growth of vegetation, Aborigines from Australia created grass fires to encourage new growth in vegetation and to allow the wild animals to eat the new plants resulting from the grass fire. They also used grass fires in order to roast some seeds that germinate only when burned. In return, these seeds provide them food.
