Please help asap!I will mark brainliest 1.what was happening in the food dye experiment at the macroscopic level?
2.what can we say about the movement of the food coloring in the center of the beaker for the hot, room temperature and cold water?
3.What was causing the movements that we observed? Why was it different at different temperatures?
4.Do you think its important to be consistent with out symbols and words on our models? Why? How can we make sure that happens?

Food coloring added to the center of a beaker of cold water will sink to the bottom. If you stir the cold water, or add the coloring to warm water, it will diffuse much more quickly.

(Apologies if I didn't answer the whole question I'm in a hurry.)

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
