Answer:

The correct answer is myofibrils

Explanation:

The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.

1. How does the inner core affect all of the Earth's other layers?
Artist 52 [7]

Answer:

With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays

Explanation:

The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.
