Calcium ions presents Ca+ binds to troponin which makes tropomyosin move out of way for myosin to attach. Cross-bridge attaches. ATP breakdown provides energy to ready the myosin head for a power stroke. Myosin head attaches to exposed binding site on actin and the power stroke is accomplished. Cross-bridge (Myosin head) springs from raised position and pulls on the actin filament. Cross bridges break, ATP binds to Cross-bridge (but is not yet broken down) Myosin heads are released from actin. As long as calcium ions and ATP are present, this walking continues until the musle fiber is fully contracted. Hope this helps!

Scorpion4ik [409]

Answer:

Drought is 19%

Flooding is 9%

Freeze is 2%

Severe storm is 15%

Tropical cyclone is 48%

Wildfire is 3%

Winter storm is 4%

Explanation:

220 + 108 + 25 + 178 + 550 +31 + 41 = 1153

Basically, you take the number of each natural disaster plus it all together. That is your total.

You then take individually the number and divide it by the total (1153), once you get a decimal number you times it by 100. Which give you the percent

You then do this for the rest of the other natural disasters.

Hoped this helped!
