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.
Answer:
1.5m/s
Explanation:
Using the formula;
Speed (m/s) = distance (metres) ÷ time (seconds)
According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m
Hence,
Speed = 90/60
Speed = 3/2
Speed = 1.5m/s.
