How could sea urchin evidence from both experiments be used to support the claim that the pH of the ocean is decreasing? A.
Experiment 1 indicates that on average, sea urchins grow to a larger size in a lower pH, and experiment 2 indicates that the majority of sea urchins fall within larger size ranges in 2010 than in 1990.
B.
Experiment 1 indicates that lower pH causes males to produce larger offspring, and experiment 2 indicates that more sea urchins fall within the largest size range in 2010 than in 1990.
C.
Experiment 1 indicates that on average, sea urchins grow to a smaller size in a lower pH, and experiment 2 indicates that the majority of sea urchins fall within smaller size ranges in 2010 than in 1990.
D.
Experiment 1 indicates that lower pH causes females to produce smaller offspring, and experiment 2 indicates that more sea urchins fall within the smallest size range in 2010 than in 1990.
