Punnett square for the original cross.
Method..safety concerns, identify controls and independant and dependant variables, procedures. 
Evidence from the experiment
Justify your results]]> 2017-04-20 13:05:08 UTC https://padlet.com/rford9/4royob4i3o3m/wish/167245488 Claim: aaabigailmccoy https://padlet.com/rford9/4royob4i3o3m/wish/167246496 Our group is trying to verify explanation 2:
 Some environmental factors, such as the amount or the intensity of light, have no influence on the genotype of tobacco plants, but these factors can alter the phenotype of a tobacco plant as is grows.]]> 2017-04-20 13:08:18 UTC https://padlet.com/rford9/4royob4i3o3m/wish/167246496 aaeileencollins https://padlet.com/rford9/4royob4i3o3m/wish/167246948 Controls: # of seeds, amount of water, petri dish, type of filter paper
Independent Variable: light intensity 
Dependent Variable: leaf color]]> 2017-04-20 13:09:50 UTC https://padlet.com/rford9/4royob4i3o3m/wish/167246948 procedures: aaabigailmccoy https://padlet.com/rford9/4royob4i3o3m/wish/167247069 Step 1: Put on safety equipment.
Step 2: Gather materials listed.
Step 3: Place filter paper on the bottom of each petri dish.
Step 4: Divide the 200 seeds among each petri dish.
Step 5: Add water into each petri dish.
Step 6: Place one petri dish underneath the florescent light rack, another on the window seal, and the last petri dish ]]> 2017-04-20 13:10:18 UTC https://padlet.com/rford9/4royob4i3o3m/wish/167247069 materials: aaabigailmccoy https://padlet.com/rford9/4royob4i3o3m/wish/167249500 3 petri dishes (used as the growth chamber)

 Water bottle with distilled

 200 tobacco seeds

 Filter paper ( you can keep the tobacco seeds wet using filter paper and the bottom of the   petri dish)


Florescent light rack

2. keep seeds away from face
3. never do two things at once
4. report all accidents/spills
5. no food or drinks
6. no horseplay

We believe this is a result of not enough water so, we are slightly going to increase the amount of water. ]]> 2017-05-01 13:24:37 UTC https://padlet.com/rford9/4royob4i3o3m/wish/169159904 Conclusion aaabigailmccoy https://padlet.com/rford9/4royob4i3o3m/wish/170156848 no light petri dish:
-44 sprouts: all white
controlled peti dish (window):
-74 sprouts: 19 white, 55 green 
florescent light rack: 
-1 sprout: green
Ratio:
63:56 = 7:6]]> 2017-05-05 12:23:31 UTC https://padlet.com/rford9/4royob4i3o3m/wish/170156848 Conclusion: aaabigailmccoy https://padlet.com/rford9/4royob4i3o3m/wish/170157870 Claim # 2 was correct based on the experiment, due to the tobacco seeds which did not have any light changing their phenotype to white in all of the sprouts. It can be proven that light did have an effect due to the controlled variable sprouting more green tobacco plants than white. ]]> 2017-05-05 12:28:16 UTC https://padlet.com/rford9/4royob4i3o3m/wish/170157870
