Answer:
E. bind to troponin which moves the tropomyosin
Explanation:
calcium ions bind to troponin, causing conformational changes in troponin that allow tropomyosin to move away from the myosin binding sites on actin. Once the tropomyosin is removed, a cross-bridge can form between actin and myosin, triggering contraction
The answer is B. Heterotrophs. All animals and fungi are heterotrophs. Hope I helped!
3.5 meters = 350 centimeters
Formula: multiply the value in meters by the conversion factor '100'.
So, 3.5 meters = 3.5 × 100 = 350 centimeters.
The answer is X is equal to Z
Y+X=Z+Y
Y=Y
Z=X
