Answer 1

First of all, before going to discuss the experiment's results, ABA is a plant hormone that inhibits seed germination, opposite to the acción of GA. Then we expect that the greater the ABA concentration, the less seeds will germinate, and the greater seed germination rate will show in the control group (the minimum ABA concentration).

Now, what do we see in the experiment. We have two repetitions of the experiment.

In the first experiment for carrot we can see a 95% of germination in the control group, a very low 19% in the high ABA concentration (10-4 molar) and a reduced 81% at low ABA concentration (10-6 molar). Just as expected.

In the same first experiment but for radish we see 86% in the control group, an extremely low rate of 6% in high ABA concentrations, but an unexpected 95% germination rate at low ABA concentration. The results were not completely the expected.

In the second experiment for carrot we have low values, 3% for the control, and rarely higher values with ABA, as the high concentration has a 7% and the low concentration has a 5%. This value variation is minimal but not expected

In the second experiment for radish we found 81% rate for the control, 6% for high ABA concentration and 90% for low ABA concentrations.

Now for GA, it is a plant hormone that promotes seed germination, opposite to the acción of ABA. Then we expect that the greater the GA concentration, the more seeds will germinate, and the greater seed germiantion rate will show in the highest GA concentration.

Now, what do we see in the experiment. We have two repetitions of the experiment.

We found, in the first sampling, a control of 95% in the control for carrot, 96% for high concentration and 91% for low. Not completely expected. And for the second, 3% for control, 2% for high and 7% for low.

Now for radish, for the control 86%, 98% for high and 96 for low. As expected. In the second one, 81% for control, 85% for high and 83% for low. Just as expected

Well, to be able to say if the results are significant or insignificant we would need to apply a test that could prove such statements by exhaustive analysis, this is not the case. We can only guess and discuss shallowly the charts as we did.
