2. In the ENSO cycle, by how many degrees does the sea surface temperature typically deviate from normal within the defined Niño 3.4 monitoring region of the equatorial Pacific Ocean, and how do the deviations differ between El Niño and La Niña (hint: interpret the Ocean Temperature Departure from Normal - Niño 3.4 graph in the ENSO section)?

Astudent conducts an experiment to see how music affects plant growth. the student obtains four identical plants. each one is potted in the same type of soil and receives the same amount of sunlight and water each day. plant a listens to classical music for three hours each day. plant b listens to rock music for three hours each day. plant c listens to country music for three hours each day. plant d does not listen to any music at all. 2. based on the experiment in the scenario, which visual aid would be most in showing the change in the plants' heights over time? a. a pie chart b. a line graph c. a timeline d. a bar graph
