@KaoKao Well, there are only two fundamental ways of reproducing: sexually and asexually. Humans are sexual reproducers, plants and others often reproduce asexually. Asexually is sometimes referred to as cloning.  Also, consider how different all humans look from everyone else on Earth (I'm treating genetic twins as one individual). That should let you answer the first one.

Do you know what an arthropod's exoskeleton is made of?

Um, it's rough materials such as chitin and calcium carbonate?

Yep. Now what other organisms have exoskeletons?

@KaoKao Hint: the shells of turtles arise for the vertebrae (for the top piece).

Sorry, I'm trying to get a timed test done while working on this review. Um, insects such as grasshoppers, and wingspanroaches, mollusks, lobsters and crabs, etc.
