A person consume more than required garlic, herbal products, omega 3 fatty acids, fortified juice, organic milk. She is also taking aspirin. And now experiencing bruising. What questions a nurse can ask her so that her diet can be improved to reduce the risk of cardiovascular disease?

Describe each of the four classes of macromolecules (large polymers) of living things, carbohydrates, lipids, proteins, and nucleic acids. Include the following items. monomer units (not for lipids) function and location of molecule in living things one example of each class of macromolecule (examples of proteins - amylase, collagen) describe the structure of each class.

It is common practice to dump strong acids and bases (nitric, sulfuric, NaOH ect.) down the drain into the water supply after dilution and mixing with sodium bicarbonate. Are sanitary plants able to filter out 100% of these chemicals before being put back into circulation or the enviornment? What are the possible health and enviornmental effects of this practice?

Explain the difference between a human right and human need. identify the relationship between rights and needs.

Calculate the volume, in liters, of 1.616 M KOH that must be added to a 0.129 L solution containing 10.85 g of glutamic acid hydrochloride (H3Glu Cl–, MW = 183.59 g/mol) to achieve a pH of 10.17. Glutamic acid (Glu) is an amino acid with pKa values of pKa1 = 2.23, pKa2 = 4.42, pKa3 = 9.95.

1.The same amino acid sequence protein produced in bacteria can have different bioactivity than when produced in mammalian cells. Explain why.

2.Carbohydrate conversion to energy that cells can use has a component that occurs in the cell cytoplasm and a part that occurs in the mitochondria. In cancer cells, how does this get altered?
