Question
Like all living things, cells need to maintain homeostasis, or a state of internal stability. To do this, cells must be able to bring in essential molecules and expel waste products. These molecules move in and out of the cell by crossing the cell membrane.
Some molecules can cross the cell membrane without using cellular energy. This movement is called passive transport. Other molecules need to use energy from the cell to move across the membrane. This movement is called active transport.
Select the true statements.
Responses
some molecules require energy to pass the membrane

passive transport does not use energy

Here are the assessments of the statements you provided:
1. **some molecules require energy to pass the membrane** - **True**
2. **passive transport does not use energy** - **True**
3. **cells must maintain a stable internal environment** - **True**
4. **the cell membrane prevents any molecules from entering the cell** - **False**
The cell membrane does not completely prevent all molecules from entering; it selectively allows some molecules to pass while blocking others, thus maintaining the cell's internal environment.
