Proteins serve as antibodies.
Answer: It will affect muscle contraction because it is needed for the formation of muscle contraction cross-bridge.
Explanation: During muscle contraction calcium binds to troponin, a protein complex that regulates muscle contraction by exposing the binding site of actin filament. Actin filament active site is where myosin head binds to, creating a cross-bridge using enzyme ATPase to speed the reaction. Calcium ion are needed to activate troponin movement, otherwise it stays in its inactive form blocking the active site of actin filament. Without calcium ions, troponin will not move and there will be no muscle contractions.
what you mean in this question?
Answer:
its gonna be D
Explanation:
It can't be A, since cells only divide once they are past interphase
It can't be B, becuase cell division does have an order
It can't be C, becuase a dying cell is still a functioning one
And it is D becuase daughter cells are haploid, while parent cells are diploid
Answer:
yes by 0.3

i think that's the answer
