Question about physiology.

In order to answer your question, you need to know what is titin. Titin is a protein that is considered the largest of its kind, and is the most abundant after myosin and actin (Did you know that?). Titin is responsible for the passive elasticity that you have in your muscles. This protein is very important when it comes to the assembling of striated muscle tissues.

The answer to your question is A. stabilize the position of the contractile filaments, because titin connects the Z disc to the M line (sarcomere).

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
