Question

1. consumption of which of the following is most likely to raise your hdl and also lower your ldl levels? a trans fats b. saturated fats c. lard d. polyunsaturated fats e. margarine 10. plaque formation in arteries: high levels of ldl cholesterol in the bloodstream can lead to formation of plaques in the arteries a cholesterol b. ldls c. polyunsaturated fats c. hydrogens e. hdls 11. which of these molecules is a monounsaturated fatty acid? a b c d

Explanation:

1. Polyunsaturated fats are known to increase HDL ("good" cholesterol) and decrease LDL ("bad" cholesterol) levels. Trans fats and saturated fats raise LDL; lard is high in saturated fat; margarine varies but often has trans fats historically.
2. High LDL cholesterol leads to plaque formation in arteries, as LDL carries cholesterol that deposits in arterial walls.
3. A monounsaturated fatty acid has one double bond in its carbon chain. (Note: Molecular structures in options A-D are not fully legible, but typically this is identified by a single C=C bond in the fatty acid tail.)

Answer:

1. D. Polyunsaturated fats
2. A. cholesterol
3. (Depends on legible structure; assume the option with one double bond, e.g., if C has one double bond, then C)
