Answer:
Substances can pass through them
Explanation:
- When a wall or membrane is permeable, it means that substances can pass through it from one side to another.
- Alveoli and capillary have permeable walls.
- Alveoli are found in lungs. They need permeable walls for exchange of gases between the body and the environment.

Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they "pull apart" and create trenches. When they converge they "push together" and create ridges, subduction happens here. The tectonic plates move on the mantle of magna from convection currents creating these different boundaries.
Have a nice day!
