Which of the following would be a good prediction for an experiment exploring how rainy days are related to photosynthesis?If photosynthesis is measured in plants over the course of many days that vary in the amount of rain, there will be a negative correlation between the amount of rain and the rate of photosynthesis.When it is rainy, plants have lower rates of photosynthesis because they have less light energy available.If photosynthesis is measured in 100 plants over the course of 100 days that vary in the amount of rain, there will be a negative correlation between the amount of rain (mm) and the rate of photosynthesis (change in plant mass in grams).If photosynthesis is measured in 100 plants over the course of 100 days that vary in the amount of rain, there will be a difference in the rate of photosynthesis over those 100 days.

Which of the following would be the best hypotheses about how rainy days influence photosynthesis in plants? Be sure to consider all aspects of a good hypothesis, not just the logic.Select the two best hypotheses.On rainy days, plants have lower rates of photosynthesis because of the interaction between rainy days and photosynthesis. Plants that live in rainy regions have greater rates of photosynthesis because they have more water, which is required for photosynthesis.When it is rainy, plants have lower rates of photosynthesis because they have less light energy available.Plants engaging in more photosynthesis will increase the amount of rain because plants remove water from the soil and put it into the air during the process of photosynthesis. Plants that live in rainy regions have lower rates of photosynthesis (on average). If photosynthesis is measured in 100 plants over the course of 100 days that vary in the amount of rain, there will be a negative correlation between the amount of rain and the rate of photosynthesis.

A scientist studies climate change and its possible effects on rain forest species. She collects data to determine the relationship between rainfall and plant productivity, and creates this graph.Using these data, what would be a reasonable prediction about species survival?Group of answer choicesA decrease in annual rainfall could cause a decline in rain forest species.An increase in the intensity of tropical storms could cause widespread extinction of rain forest species.A decrease in the intensity of tropical storms could improve the survival of some rain forest species.An increase in annual rainfall could cause widespread extinction of rain forest species.

Over the past year, every time it has rained, the temperature has dropped significantly. What can be inferred about rainy days?Rain causes the ground to cool.Rainclouds block the sun, lowering the temperature.Rain and temperature are not related.Rain is related to a temperature drop

Which of the following changes would most likely reduce the rate of photosynthesis?A.Decreasing wind speed past a plantB.Increasing the temperature around a plantC.Moving a plant closer to a light sourceD.Shortening the length of a plant's light exposure

Based on the results of this experiment, which of the following best describes how the rate of photosynthesis changes from low %PAR to high %PAR?Photosynthesis decreases, levels off, then increases.Photosynthesis remains constant and then increases.Photosynthesis decreases, increases, then decreases again.Photosynthesis increases and then decreases.Photosynthesis increases, decreases, then increases again.Photosynthesis increases, levels off, then decreases.
