1.Discuss the possible health effects of a high sodium diet
2.How was your sodium intake? See the Nutrition Report and identify the amount consumed. Did you meet or exceed your sodium target? If it was high, identify foods from your Servings Report that contributed the most sodium. If you met the recommendations, discuss the strategies that helped you.
3.Discuss the long-term health consequences of a sedentary lifestyle.
4. How might a deficiency in iron affect a person's health? Discuss the long-term health effects of a chronic deficiency in calcium.
5 How might a consistently high consumption of sugar, especially added sugars, affect a person's health long term?
6.How might a consistently high consumption of saturated fats and /or trans fats affect a person's health long term?

You have a sample of ssDNA molecule that you will use as a primer for PCR. You dissolved the dried ssDNA peller in TE to a total volume of 400 ul to make a "stock DNA sample." You need to determine the concentration (ug/ul) of this primer DNA in solution. To do this you took 4 ul from the "stock DNA sample" and added these to 996 ul of TE buffer in a cuvette, making a total of 1000 ul in a cuvette. Next, you determined the absorbance of 260 nm light for this 1 ml of diluted DNA in the cuvette and the A260 value is 0.014.
1) what is the concentration (ug/ul) of the DNA solution in the cuvette?
2) what is the concentration (ug/ul) of the primer DNA in the original Stock DNA sample?
3) what is the total amount (ug) of DNA in the stock DNA sample tube?
4) how many ul of the original "stock DNA sample" would you need to use in a PCR experiment that required a total of 0.25 ug of DNA from this sample?
