A science class conducts an experiment about temperature and the motion of particles. The students are given three cups. Each cup holds 150 milliliters of water. Cup A has water at room temperature, cup B has cold water, and cup C has very warm water. The students add three
drops of red food coloring to the center of each cup at the surface of the water. They observe the water for 1 minute.
What is the responding variable in this experiment?
O A. the number of cups
O B. the temperature of the water
O c. the amount of water in each cup
O D. the rate of dispersion of the food coloring

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
