Activation of muscle contraction could be a speedy event that's initiated by electrical activity within the surface membrane and transversal (T) tubules. This can be followed by unharness of metal<span> from the inner membrane system, the sarcoplasmic reticulum.
</span>Nervous stimulation causes a depolarization<span> of the muscle membrane (sarcolemma) </span>that<span> triggers </span>the discharge<span> of </span>calcium<span> ions from the sarcoplasmic reticulum.</span>

<span>The burners must be turned off because, in the case of liquid chromatography, the eluant solvents being used are flammable. Leaving the burners lit could cause the eluant to catch on fire, putting the scientist at risk.</span>
Question : T<span>he humpback whale can be seen off the coast of Alaska during the summer months, but is found as far south as California and Hawaii during the winter. Why would the humpback whale most likely spend the summer months off the coast of Alaska?
Answer : The humpback whale likes being in the cold like all other fishes.
The humpback whale is usually found around the coast of Alaska because it is a little colder over there. Then in winter it is found around Hawaii and California because the pacific ocean cools down and is not so hot anymore!
