D. fingernails
Skin, hair, and vertebrae are all the outer layer of the body and protect the body. The fingernails aren't part of that.
Homologous and analogous structures are two types of evolutionary evidence, taken together, provide strong evidence for when extinct species most likely diverged from common ancestors, relative to other events happening on Earth.
Several types of evidence support the theory of evolution: If two or more species share a unique physical feature, such as a complex bone structure or body plan, they can all inherit this property from the common ancestor. Physical traits shared through evolutionary history (common ancestor) they say they are homologous. Not all physical properties that look similar are signs of common ancestry. Some physical similarities instead are analogous: they evolved independently in different organisms because organisms lived in similar environments or experienced similar selective pressures.

The hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called the recovery stroke.
<h3>What is myosin ? </h3>
Myosins are a class of motor proteins well recognized for their functions in the contraction of muscles and a variety of other eukaryotic motility processes. They are ATP-dependent and in charge of motility based on actin. By Wilhelm Kühne, the first myosin was identified in 1864.
<h3>When the myosin pulls the actin what is happening?</h3>
The actin is drawn along by the myosin head as it advances in the direction of the M line. The filaments migrate nearer the M line by around 10 nm as the actin is tugged. The power stroke is the name given to this motion because it is where force is generated.
