Question

scientists have believed for many years that marine temperatures drop as ocean depth increases. what experimental method would best test this hypothesis, and why? (1 point)

• bring samples of ocean water from various depths to the lab and measure the temperature of each sample, because this most directly measures water temperature
• send a robot to measure the temperature of the ocean at various depths and plot the data on a graph, because ocean temperature may change with depth
• capture fish from various ocean depths and measure the temperature of their tissues, because this directly measures the temperature of living systems
• collect rocks from various ocean depths and determine what temperature was present during the rocks’ formation, because rocks do not change once they are formed

interpreting the results of an experiment requires critical thinking skills and the ability to make connections across data. which skill would most likely benefit a scientist who is doing this? (3 points)

• creativity
• inflexibility
• time management
• memorization

Explanation:

First Question (Experimental Method to Test Marine Temperature Hypothesis)

To test if marine temperatures drop with depth, we need a method that directly measures water temperature at various depths. Bringing ocean water samples to the lab (first option) directly measures water temperature. Sending a robot to measure and plot (third) is about plotting, not direct measurement. Capturing fish (second) measures fish tissue temp, not water. Collecting rocks (fourth) measures rock formation temp, not water. So the best is the first option.

Interpreting results and making connections across data needs creativity to find patterns/links. Inflexibility is bad for connections. Time management and memorization don't help with data connections. So creativity is the key skill.

Answer:

A. Bring samples of ocean water from various depths to the lab and measure the temperature of each sample, because this most directly measures water temperature
