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.

<span>The organic molecules that must be included in the soil for earthworm nutrition are Neutral pH. A neutral pH substance that is neither basic nor acidic is considered neutral. The pH scale is the one that measures how a substance is basic or acidic. It ranges from 0-14. A 7 pH is neutral.</span>
Answer:
Option 1, No. The highest frequency of heterozygotes under Hardy-Weinberg equilibrium is 0.5
Explanation:
As per Hardy Weinberg’s equilibrium principle, the maximum frequency of heterozytotic individuals occur only when half of the population is dominant and recessive homozygous.
In other way when the sum of frequency of dominant and recessive species is equal to 0.5, only then the frequency of heterozygotes is maximum which in any case would not be higher than 0.5.
Hence, option 1 is correct
<span>In humans, oogenesis
in comparison to spermatogenesis is different in that the temperature they have.
Female puberty typically occurs much later than the age of male puberty oocyte
production works best at cooler temperatures than those that support
spermatogenesis oogenesis continues throughout life, but spermatogenesis
typically ends.</span>
