Answer:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
Natural selection only occurs when there is a superiority within a species set. If there is no genetic variation, no single animal is any better than the next, making the presence of superiority impossible and survival left up to chance. In this case it would be considered genetic continuity.

Acronyms are abbreviations for words like what does it stand for and its basically used to make words stand out and turn long words shorter like for example. VIP is very important person, MVP is most valuable player, and YOLO is you only live once, things like those are meanings in just a small word.
