Answer the following question given this paragraph: Corals form large colonies in shallow tropical water. They are confined to shallow water because they have a symbiotic relationship with algae that live inside of them. The algae need sunlight for photosynthesis, so they must stay relatively close to the surface of the water to get enough light. Corals exist only as polyps. They catch plankton with their tentacles. Q: Coral and the algae living inside of them have what type of relationship, since the algae relies on the coral to stay close to the water's surface? Choices: - peculiar - competitive - parasitic - symbiotic A:
symbiotic

Answer the following question given this paragraph: A mudslide is the sudden flow of mud down a slope because of gravity. Mudslides occur where the soil is mostly clay. Like landslides, mudslides usually occur when the soil is wet. Wet clay forms very slippery mud that slides easily. You can see an example of a mudslide in Figure below . Q: What do you call the sudden flow of mud down a slope because of gravity? Choices: - rockflow - typhoon - mountainside - mudslide A:

Ques: Answer the following question given this paragraph: Tubeworms deep in the Galapagos Rift get their energy from chemosynthetic bacteria. Tubeworms have no mouth, eyes, or stomach. Their survival depends on a symbiotic relationship with the billions of bacteria that live inside them. These bacteria convert the chemicals that shoot out of the hydrothermal vents into food for the worm. Q: Tubeworms deep in the galapagos rift get their energy from what type of bacteria? Choices: - sprillia - filamentous - asexual - chemosynthetic A:
Ans:
chemosynthetic
