Answer: B. The release of calcium ions causes myosin and actin to attach to each other. This statement best describes a cause and it's effects that occur during the process of muscle contraction.
Muscle contraction can be explained by sliding filament theory.
1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.
2.Contraction of muscles: calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.

Answer:
Electrolytes
Explanation:
An electrolyte is a substance that conducts electricity when dissolved in a polar solution e.g water. They are particles that carry a positive or negative electric charge called Cations and Anions respectively.
Electrolyte can also be referred to as a substance that dissociates into ions in solution and acquires the capacity to conduct electric currents. It becomes an ionic conductor when fused or dissolved in a suitable solvent.
Electrolytes include Sodium, pottasium, calcium, bicarbonate and magnesium amongst other body minerals. These minerals carry a small electric charge in fluid environment.
It is controlled by the nucleus which creates RNA, which is processed by the ribosomes causing the eukaryotic cell to do things
