Well you see unicellular organisms are very unique in the fact that they live all on their own and move around with a flagellum or little motor, but to the point unicellular organisms carry out essentially every function in life and they must in order to simply survive. So it's most likely D.
Answer:
Simulation, in industry, science, and education, a research or teaching technique that reproduces actual events and processes under test conditions. ... The interaction of these phenomena create new situations, even new rules, which further evolve as the simulation proceeds.
The correct answer is - C. Warm water is carried to cooler parts of the ocean.
The Gulf Stream is warm ocean current. It is an ocean current that originates from the Caribbean region, where it is constantly warm throughout the year. Because of that, the water is warm as well, and since the warm water is less dense, it moves on the surface. The movement is toward the higher latitudes, where this current, as a surface movement of the water, is bringing warmer water to the cooler areas, such as the eastern coast of the United States. Not only that warm water is brought to these areas, but the Gulf Stream also brings in warm and moist air masses with it, making the climate much more mild, and increasing the amount of precipitation.
