A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.

Hello there!
I do not know what the statements are but i will explain some characteristics of the beach to you!
Beaches are made of sand, they are along the coast, the coast is when a state (such as California) is along the beach, or the ocean, beaches also sometimes have trees, but usually when the ocean rises the ocean takes the tree into its depths. That's why sometimes you see tree trunks on the beach, but be careful sometimes if you sit on them they will cave in because of all the salt it absorved from the oceans water, sometimes you will see seagulls, seagulls like to eat the fish from the ocean, and/or the crabs that wash up on shore.
I hope this helped you!
Good luck!
