Answer:
Hormones communicate between plants and signal to ripen further the release of ethylene helps in this ripening as well.
Explanation:
- When a green banana is placed closely to a brown banana it will ripen more quickly and would turn yellow because the brown banana releases a chemical called ethylene.
- Ethylene is gaseous is nature and is thus, able to affect plants that lie close to it and this is the reason why ethylene is known as a fruit ripening hormone.
- The amount of ethylene increases in fruits as the fruit further ripens and hence, when placed next to a brown banana the green banana will ripen more quickly and turn yellow.
It has evaporated and turn into gas however if it didn’t dry up animals could have taken it
