Alternative- Will affect germination

H2O affects # of seeds germinated

Evidence:

~5ml->1.67 seeds (Avg)

~10ml-> 7.4 seeds (Avg)

~No overlap (Between error bars of 5ml and 10ml data)

Reasoning:

~Softens seed coat

~Provides Dissolved Oxygen

~Speeds reactions inside seed

~Activates enzymes of respiration

C.E.R:

Water affects the number of seeds germinated in seventy-two hours. As seen in the data, the seeds with 5ml of water averaged 1.67 seeds while the seeds with 10ml of water averaged 7.4 seeds. In the graph there were no everlapping error bars with the 5ml and 10ml of water. This shows that water affects the seeds because the more water they had the coat of the seed softened, the water is abbsorbed and gives dissolved oxygen to the seed, and the water also activates the enzymes and initiates respiration in the seed.

Alt- Moisture will affect the number of bugs in the choice chamber.
