Answer:
<em><u>the North American Continent is ripping itself apart.</u></em>
<em><u /></em>
Explanation:
<em><u>Landscapes within the western us are characterised by long, parallel mountain ranges separated by down-dropped valleys. These landscapes are a results of continental rifting, or places wherever the continental crust is extending and dilution. because the crust thins, the hot, buoyant layer (the asthenosphere) rises. Eventually, the layer upwells therefore on the brink of the surface that rock that erupts onto the surface. Continental rifting processes are showcased within the steep fault escarpments and active volcanoes that characterize the western us.</u></em>
A) Infiltration allows for groundwater filling
Explanation:
Ground water is related to infiltration in that the ground water system gets filled by infiltration.
Ground water is the water beneath the earth surface.
- Infiltration allows for water to percolate into the ground.
- The water moves through the pore spaces in rocks and they collect in an aquifer which is a natural underground storage for water.
- Infiltration is a component of water cycle by which the ground water system is recharged.

The ends of the actin filaments are anchored to the Z-line or disk.
The sarcomere is the primary functional unit of muscle fiber. It is flanked by a Z-band on each end with adjoining I-bands. The Z-band or disk is a dense fibrous structure composed of actin, α-actinin as well as other proteins.
Thin filaments or actin filaments are anchored at one end at the Z-band. Titin is connected to both the Z-band and the M-line. Thick filaments are attached in the middle of the sarcomere at the M-line.
An intermediary filament protein forms a meshwork from one Z-disk to the next across the myofibril. These networks are joined by actin through the protein dystrophin to the sarcolemma.
