Question

Suppose that you were a researcher trying to understand how rising levels of atmospheric CO2 might affect ragweed plants, and thus seasonal ragweed allergies. What questions, hypotheses, and predictions might you want to study

Answer 1

Prediction a - Plants grown at higher CO2 levels will produce more pollen.

Hypothesis 2 b - CO2 levels affect the concentration of protein allergens in ragweed pollen.

Prediction c - Plants grown at higher CO2 levels will produce higher concentrations of allergens.

Researchers developed two hypotheses to explain why ragweed allergies appear to be getting worse as the global climate changes.• CO2 levels affect ragweed pollen production, with plants that grow at higher CO2 levels producing more pollen.

CO2 levels affect the concentration of allergens (the proteins that actually trigger allergic reactions) found in ragweed pollen, with plants that grow at higher CO2 levels characterized by pollen with higher concentrations of allergens.
