Final answer:
The level of tension generated by a muscle fiber depends on various factors, except for the amount of water in a muscle fiber.
Step-by-step explanation:
The level of tension or strength of contraction generated by a muscle fiber depends on several factors. However, the factor that does not affect muscle contraction is the amount of water in a muscle fiber. The other factors that influence muscle contraction include body temperature, the frequency of nerve stimulus, and the muscle fiber's starting length.
