The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.
<h3>What is the smallest contractile unit within skeletal muscle?</h3>
A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.
In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

Answer:
the 2 pne pretty sure its that
The levels of an environment to be organized are populations,species,community,and the ecosystem
The error is that four haploid daughter cells are made so it needs to be 4N, because there should be 4 instead of 2
Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
