<h2>Gap junctions </h2>

Explanation:

  • Skeletal muscle also called as voluntary muscle, is anchored to bone by tendons and is used to effect skeletal movement in activities such as locomotion and maintaining posture
  • Muscle associated with heart is called cardiac muscle is also an involuntary muscle but is more akin in structure to skeletal muscle
  • Both cardiac and skeletal muscles are striated, they contain sarcomeres and are packed into highly regular, repeating arrangements of bundles
  • Skeletal muscle do no have gap junctions because they are not single cells
  • The gap junctions, which are protein-lined tunnels, allow direct transmission of the depolarizing current from cell to cell, across the chambers of the heart, so that the cells contract in unison
  • Because of the way these gap junctions function, the cardiac muscle cells are said to be electrically coupled

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.
