Question

1. which type of molecule is hydrophobic and has the basic structure of a long hydrocarbon chain? a. lipids b. carbohydrates c. nucleic acids

Explanation:

Lipids are hydrophobic (water - fearing) molecules. Some lipids, like fats, have long hydrocarbon chains. Hydrocarbons are non - polar and do not interact well with water (hydrophobic). Carbohydrates are generally more polar and can be hydrophilic (water - loving) to some extent. Nucleic acids (DNA and RNA) have charged phosphate groups and are also hydrophilic.

Answer:

A. lipids
