Saturated Salt Solution
How many grams of salt did it take to saturate 50ml of water? What does saturated mean? What did we use as a solute? Do you think the water could hold more salt if the water was heated or cooled?
Natural Selection Graphs and Analysis
For the Natural Selection Lab, make graphs for all of your data. If you did not finish the lab, make prediction graphs for the parts you did not finish and explain why you predict these results. For your analysis, explain the results of each simulation, to include the questions asked on yesterday's blog post. Include how this activity was a representation of actual events. Also include the limitations of this activity (for example, how could you have manipulated the results)

Natural Selection Lab
How did the color of the environment (paper) effect the population (macaroni)? What happened after several generations? What do you predict will happen when you use white paper? What do you think would happen to these species if there were no predators? What would need to occur for speciation to occur? How does this activity relate to evolution, natural selection and the fitness of a species?

Cracking Your Genetic Code Response
What do you think are the benefits and disadvantages of knowing the contents of your genome? Would you want to know your chances of getting a disease that you could do little about (like Huntington's disease)? What would be the consequences of knowing? Do you think those consequences out weigh the benefits? Would you do things differently if you found out that you would get the disease? If so, what would you do differently? If not, why?
Your response should be a minimum of 250 words and answer all of the above questions. Responses should show thoughtful reflection. I recommend that you copy and paste your comment from a word document just in case it erases (so that you do not cry yourself to sleep). You are welcome to turn in a hard copy. This will replace a test for CH 14 and will be worth 50 test points.

Salt Solution
How were you able to determine the mass of the salt in your salt solution? Was this a direct or derived measurement?

Banana DNA
Why did we add each solution to the banana? Describe what the DNA looked like. Do you think it would differ in appearance if we used a different fruit? Why/why not?
