Answer:
The researchers' experimental hypothesis was that changes in actin and myosin overlap would alter the number of myosin cross- bridges that could form within a sarcomere, and specifically that (Primer Section Key Terms O)
A. Increases in overlap favor more cross-bridges to form, increasing muscle force. muscle force. effect on muscle force. fiber) lengths.
Explanation:
Physiologists Alfred Gordon and Fred Julian and Andew Huxley investigated on the strianed muscle´s contraction properties, to demonstrate the way the muscle lenght is affected by changes in overlap between myocin and actin causing the number of cross-bridges increase , increasing muscle´s force as well.
No cross-bridge disruption is caused, nor litlle differences or minimal overlap so B, C and D options are not correct.
Answer is False took biology last year lol
Answer:
On slim shady's grave please stand up
Explanation:
1. natural selection acts on existing traits because you can not evolve into something you didn't have
2. original structures evolve to accomplish new function in order to survive
