Question 1
How do bats find their way around and hunt for food in the pitch-black night?
Answer
They use echolocation with sound pulses
Bats use echolocation to navigate and hunt in the dark by emitting high-frequency sound pulses and listening for the echoes that bounce off objects.
Question 2
Why do pumpkins and gourds count as fruits instead of vegetables?
Answer
Because they grow from flowers and have seeds
Botanically, pumpkins and gourds are fruits because they develop from a flower and contain seeds, even though we often treat them as vegetables in cooking.
Question 3
What happens in autumn that causes leaves to lose their green color and show off yellow shades?
Answer
The trees stop producing chlorophyll
Leaves change color in autumn because trees stop producing chlorophyll as daylight decreases, allowing other pigments like yellow carotenoids to become visible.
