I think the correct answer would be D. Actin and myosin are completely overlapped would sum up the three steps of a muscle contraction. For it to happen, troponin and tropomysin should be moved in order to show the myosin-binding sites.

What are beneficial traits?
AURORKA [14]
 <span>Beneficial traits are inherited traits (they may be phyical, biochemical, or behavioral) which increase an organism's fitness. Fitness is the technical term in biology for an organism's ability to reproduce itself, compared to other organisms. A beneficial trait, then, may either (1) increase the number of times which an organism reproduces, (2) increase the number of offspring which an organism has per reproductive act, or (3) increase the fitness of individual offspring. These three are not, of course, mutually exclusive. </span>
