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.
While both show the process of natural selection, vestigial structures no longer have a working function, but are still present in an organism. An example of this in humans is the appendix. To humans, it doesn't necessarily serve any function, but it is just there as part of the human body.
On the other hand, analogous structures are similar structures in different species that perform the same function. We can think of it as wings on a moth, bird, and a fly. While the three do not share a common ancestor, the structure of the wings are said to be analogous.
Nitrogen and phosphorus, they aren’t in a form that can be directly taken up by an organism.
