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.
- Capillaries are a type of blood vessels. They need permeable walls for exchange of nutrients and waste material between the blood and the tissue.
Answer:
This region of the United States has been tectonically active since the super continent Pangea broke up roughly 200 million years ago, and in large part because it is close to the western boundary of the North American plate. Since the formation of the San Andreas Fault system 25-30 million years ago, the juxtaposition of the Pacific and North American plates has formed many faults in California that accommodate lateral motion between the plates. North and east of California, the Basin and Range province between the Wasatch Mountains in Utah and the Sierra Nevada Mountains in eastern California is actively spreading and stretching westward.

Titanium is a strong, light metal. It is as strong as steel and twice as strong as aluminum but 45% lighter than steel and highly resistant to corrosion. It is used in making alloys and is mostly added to steel because it increases the strength and resistance to corrosion of steel.
Titanium - steel alloys are particularly useful in spacecraft and aircraft applications which account for about 65% of all Titanium sold. These alloys find a host of other applications such as in manufacture of jewelry, bicycles, golf clubs, various sports equipment and also in the medical field as artificial hips, knees and specialized dental implants.
