Question

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.
a. rinsing does not affect KAR
b. KAR with no rinse = Group 2
c. KAR with rinse = Group 5
different than
d. Controls = Group 1, Group 4

Answer 1

The student hypothesizes that rinsing does not affect the binding of KAR to seed receptors, comparing KAR without rinse (Group 2) and with rinse (Group 5) against controls (Group 1, Group 4). Without experimental data, the claims are hypothetical.

Step-by-step explanation:

The student's question pertains to the effect of rinsing on the binding of KAR (karrikin) and TMB (presumably another substance) to seed receptors, as well as the comparison of these agents with appropriate control groups in an experiment. Based on the provided context, one can make claims about whether rinsing the seeds has an impact on the binding affinity of these substances to the receptors, which could affect germination processes or growth. However, due to the lack of specific data in the scenario, a factual claim cannot be made without further information on the experimental design and results.

As it stands, the student's claims suggest the following hypotheses:

1. Rinsing does not affect the binding of KAR to the receptor.
2. The binding affinity of KAR to the receptor should be the same whether the seeds are rinsed or not, as indicated by comparing Group 2 (KAR with no rinse) with Group 5 (KAR with rinse).
3. Control groups (Group 1 and Group 4) would provide baseline data for comparison to observe the effects of rinsing or the absence thereof.

However, without specific results from the experiment, these claims remain hypothetical.
