Put the following steps in order: 1. Calcium binds to troponin
3. Myosin head is release from actin
5. Electrical impulse (action potential) is
send to sarcoplasmic reticulum
7. Myosin heads are bound to actin
9. ATP binds to myosin head
2.Sarcoplasmic reticulum releases calcium
4. Motor neuron action potential is signaled
6. Tropomyosin moves exposing the active
binding site
8. Acetylcholine is release
10. power stroke/contraction

Which type of bacterial reproduction is depicted in the diagram?

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.

Which blood cell spend most of their time in the lymphatic system?
