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.

Plant reproduction by tissue culture differs from reproduction by meristem culture because
Leviafan [203]

The answer is; B

Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.
