A. Young caterpillars have to look after themselves.

B. There was a need for sorting animals and plants into groups.

C. A penguin and an ostrich are grouped together.

D. Glass is used to make windows and sunglasses​

Answer 1

A) Some caterpillars protect themselves with the poisonous chemicals from poisonous plants that they are able to eat. A predator that attacks will be disgusted and may even fall sick after swallowing the caterpillar. So, it learns to avoid the same type of caterpillars in the future and leave them alone.

B) Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.

C) Most living forms belong to the order Struthioniformes (a group that includes the ostrich, the rhea, the cassowary, the kiwi, and the emu); however, they are more commonly known as ratites. Also flightless, but unrelated to the ratites, are penguins (order Sphenisciformes).

D) Glass is typically inert, resistant to chemical attack, and can mostly withstand the action of water, making it an ideal material for the manufacture of containers for foodstuffs and most chemicals.
