Question

1. there are two lines under each of the following drawings. on the first line, write the correct name of the molecule shown. on the second line, briefly explain how you know.

Explanation:

The top - image shows a phospholipid bilayer structure which is characterized by two layers of phospholipid molecules with hydrophilic heads (the circular parts) and hydrophobic tails (the long lines). The bottom - image shows the double - helix structure of DNA, which is composed of two strands coiled around each other. The structure of DNA is well - known for its double - helix shape, and the phospholipid bilayer is a key component of cell membranes with its distinct two - layer arrangement.

Answer:

Top: Phospholipid bilayer; Bottom: DNA double - helix
