Concept explainers
To propose a hypothesis: The hypothesis in the given experiment and whether the experimental result support the hypothesis.
Introduction:
Carbon dioxide gas is a greenhouse gas which also acts as a growth and reproductive stimulator of plants through increased photosynthetic carbon assimilation. Rise in temperature is related to elevated concentration of CO2, which may lengthen the flowering season and which will further increase the pollen loads. Individuals who are allergic to pollen can suffer more in this condition.
Hypothesis: Increase in CO2 concentration increases the pollen production.
To determine: The other variables to be tested and the measurements required in the given experiment.
