Answer:
The suitable option will be - B
B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.
Explanation:
Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.
Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.
So, we can say that option B is correct.

Answer:
Technically Mitosis and Meiosis
Explanation:
Mitosis is the spliting of <em>Body Cells.</em> Mitosis goes through 4 phases that are easy to remember as PMAT. Mitosis starts with Interphase then moves to Prophase, Metaphase, Anaphase, and Telephase. These steps also occur in Meiosis. However Meiosis goes through these step twice. If you need further explaination of mitosis and meiosis I recomend the amoeba sisters.
Hope this helps!!
