a. The researcher made the following claims about the effect of KAR and the effect of TMP on seed germination
relative to the control treatment.
KAR alone affects the timing of seed germination.
KAR alone affects the percentage of seeds that germinate.
TMB alone affects the timing of seed germination.
TMB alone affects the percentage of seeds that germinate.
Provide support using data from Figure 1 for each of the researchers' claims.
b. Make a claim about the effect of rinsing on the binding of KAR to the receptor in the seed and about the effect of
rinsing on the binding of TMB to the receptor in the seed. Identify the appropriate treatment groups and results
from the table that, when compared with the controls, provide support for each claim.
C. There is intense competition by plants to successfully colonize areas that have been recently cleared by a fire.
Describe ONE advantage of KAR regulation and ONE advantage of TMB regulation to plants that live in an
ecosystem with regular fires.
