I believe its A. I could be incorrect though.
Answer: Senescent cells
The Senescence of
the eyes is often demonstrated by the presence of <span>senescence cells. They are forms of cells that are normally capable of
replication within mammalian tissues but permanently non-dividing and
share features with oncogene-induced senescence.
</span>Moreover, the accumulation of senescent cells has been overwhelmingly
studied using fibroblasts and has been proposed to act as an ageing mechanism.
Solar power/energy or hydroelectric plants
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move.
4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea.
5. An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption.
6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter.
7. Depends on what kind you're looking for. I'd look it up for your specific topic.
8. To apply a forces to something, usually resulting in a stretch.
9. The action of compressing something, to flatten or squeeze by pressure
10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.
11. In areas undergoing extension or stretching. It's when the crust is extended.
12. The hanging wall drops relative to the footwall.
13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)
14.
