The correct option is C.
Obligate anaerobes are micro organisms that are poisoned and killed when exposed to the normal atmospheric oxygen concentration. These organisms can only survive in the absences of oxygen, therefore, they carry out only anaerobic form of respiration in order to obtain the energy that they need. <span />
I believe it’s lactic acid fermentation! hope this helps
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.
A. animal can fly; AA. animal can't fly. That should be the correct answer. I hope that this helps you!
