Euglena is a unicellular protist. other examples of protists include amoeba and paramecium. euglena are unique because they behave like plants and like animals depending on the environment. they have a light-detecting eye spot that detects light. because of this, we might expect euglena to a) use chlorophyll to make sugar. b) search for prey as a predator. c) use the eye spot to find other euglena. eliminate d) use the eye spot to swim away from the light.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
