Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have hold fasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargasso, have gas-filled structures called floats.
Answer:
Claim 1
Explanation:
I chose this claim because I believe that when the plates under the earth move or shift, that's what causes an earthquake and when everything starts to shake. If it was the other way around there wouldn't be any reason for an earthquake to start.
hope that helped :)
