3 Which statement best describes a cause and its effect that occurs during the process of muscle contraction? A. The release of
Y_Kistochka [10]

Answer:A. The release of calcium ions causes myosin and actin to attach to each other.

The contraction of skeletal muscles takes place by induction of a nerve impulse, which produces a movement and the interaction of the filaments containing proteins named as actin and myosin. This interaction of filaments is regulated by proteins  called tropomyosin and troponin present on the actin filaments. The motor nerve causes the depolarization of the muscle membrane sarcolemma. This triggers the sarcoplasmic reticulum to release calcium ions. This calcium binds to troponin and thus allows the tropomyosine strand on the actin filament to displace so that the part of the actin where myosine head needs to be attached remain uncovered. Binding of the actin myosine filament results in contraction.

Hence, the release of calcium ions causes myosin and actin to attach to each other causes muscle contraction.

What are the reactants and the products in this equation?<br><br> 2H2 + O2 → 2H2O
Hitman42 [59]

Answer:

Reactants: hydrogen and oxygen

Products: water

Explanation:

The reactants are what goes into a reaction, i.e. what is reacting. The products are what is formed. The reactants are usually shown on the left, and the products are usually shown on the right.

We can see in this equation that hydrogen (2H2) is reacting with oxygen (O2) to form water (2H2O). Therefore the reactants are hydrogen and oxygen, and the product is water.
