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? complete the flow chart by selecting the hypothesis and predictions that follow from the question you're trying to answer. not all labels will be used.

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
