Part B: Fill in the Blank
Write the correct answer on each line.
1. A walking stick insect looks like a twig to hide from predators.
Every insect's body is split into three clear sections — the head in front, the thorax in the middle (where the legs attach), and the abdomen at the back.
2. During hibernation, a bear's heartbeat becomes very slow.
Warm-blooded means a mammal's body makes its own heat, so it stays warm even when the air outside gets cold.
3. Monarch butterflies migrate thousands of miles every year.
A penguin has feathers, a beak, and wings, and it lays eggs like every other bird — it just uses its wings to swim instead of fly.
4. A hedgehog rolls into a ball so its spines protect it.
Both have hard shells and scaly skin and are cold-blooded — all signs that they belong to the reptile group.
5. Webbed feet help ducks swim through the water easily.
Caterpillars hatch from eggs and spend their time eating leaves to grow bigger. Then they form a chrysalis and change into winged butterflies.
