The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
Climate variations are averaged by using weather conditions from past years. Climate variability varies by seasons, because some seasons get colder than others, and there could be more precipitation in the atmosphere, which would then make it easier to calculate future rainfall, making people aware of storms that are coming ahead of time and allowing them to prepare for it (making storm water drains, etc.).
