As most of you know, heart disease is america's leading cause of death. In unit one, we have discussed the different types of lipids. Please answer the following questions.

• What are the potential health consequences of coronary arteries being clogged by “plaques”

• Name some specific foods that might lead to increased LDL cholesterol in the bloodstream
• What is the main difference between a saturated fat and an unsaturated fat? List characteristics of each. Where are they found? Solid/liquid at room temp? Etc.
• What type of reaction is used to link each of the fatty acids to a glycerol molecule?
• If you wanted to raise your HDL and lower your LDL levels, what should you eat?

The extinction coefficients of the four natural nucleoside-5’monophosphates pdA, pdG, pdC and pdT at 260 nm are 1.506*10⁴ , 1.218*10⁴ , 7.10*10³ , and 8.56*10³ L/mol/cm, respectively (Cavaluzzi, M.J., Nucleic Acids Res., 2004, 32, e13). Please determine:

a) The extinction coefficient of a single-stranded, 5’-phosphorylated Dickerson Dodecamer sequence d(pCGCGAATTCGCG).

Answer: ε260 = 1.244*10^5. HOw they got that?

b) Please calculate absorbance and percent transmittance of a 10 micromolar (μM) solution of the single-stranded Dickerson Dodecamer, as described in (a), at 260 nm when a cell with the path length of 1.0 cm was used.

What is A? %T?

I don't know the answer for that.

Q1 We have naturally occurring radioactive material with the chemical formula (Ce,La,Nd,Th)(PO4,SiO4). A sample of the ore is mined and is concentrated to 5%, 10%, 25% and 100% monazite So four samples are created in 5%, 10%, 25% and 100% of this monazite.

a. Calculate the activity of the samples. Thorium 232 with a known half life in literature should be used in activity calculations.

b. would activity be different if the samples with 10% and 25% were dissolved in acids or other minerals? assume same percentages.

show all steps for the question to be worth any marks the result should be given in Bq/gram thorium 232 half life is public information and it should be used in this case.

1) A 0.23 g sample of an unknown monoprotic acid is titrated with 0.11 N NaOH. 23.89 mL of NaOH is required to reach the equivalence point. What is the molar mass of this acid?

2) You perform a phenolphthalein titration on a 0.26 g sample of an unknown organic acid, which requires 33.78 mL of 0.1008 N NaOH to reach the endpoint.

a) What is the equivalent weight (estimate) for this acid?

b) Assume the acid is monoprotic and calculate its molar mass. Assume the acid is diprotic and calculate its molar mass. Now that you have two potential molar mass values, using the list of acids in the lab, do you think this acid is monoprotic or diprotic? Explain your rationale.

In at least two paragraphs, reflect on your definition of health and how disease affects homeostasis of the human body. Include at least one peer-reviewed source in your response.

Explain the different types of health insurance programs. What are the main differences among these programs? How are they similar? Be sure to use terms that are unique to benefits, compensation, and human relations

A nonscientist friend of yours asks how findings in a worm or fly can be relevant to human biology. Explain to your friend the importance of model organisms in molecular biology research.

Discuss the pros and cons of the federal, state, and local government funding human service programs. Should they continue to do so, or should it be the responsibility of concerned citizens to “care for their own”?

Describe how the motility and secretions of the stomach contribute to the digestive process in a healthy human, making sure that you describe difference between the functional regions of the stomach.
