Which of the following best describes the numbered areas?
Understand the Problem
The question is asking to identify and explain the characteristics of specific areas in a membrane diagram based on the properties of the membrane molecules and their interaction with water. It requires an understanding of biological membranes, specifically concerning hydrophobic and hydrophilic properties.
Answer
Areas 1 and 3 are polar, since the membrane molecules are aligned with water molecules.
The final answer is Areas 1 and 3 are polar, since the membrane molecules are aligned with water molecules.
Answer for screen readers
The final answer is Areas 1 and 3 are polar, since the membrane molecules are aligned with water molecules.
More Information
In biological membranes, the polar areas typically interact with water molecules, while nonpolar areas tend to repel water.
Tips
Ensure you're distinguishing between polar (hydrophilic) and nonpolar (hydrophobic) regions correctly.
