Recall that in the Hardy-Weinberg lab we did earlier in the semester, the clams in some of the populations we studied were expos
ed to saxitoxin. Some of these clams were sensitive to the toxin. Saxitoxin affected the sensitive clams by blocking their voltage-gated sodium channels, ultimately killing the clams. Now that you know more about the role of voltage-gated sodium channels from completing this lab, explain why the saxitoxin killed those clams.
Due to failure of vital organ system and body functions
Explanation:
Saxitoxin is a toxin that acts as a blocker to the voltage-gated sodium channels. It binds to voltage-gated sodium channels within the muscle and the nerve fibers and causes Paralytic Shellfish Poisoning following bioaccumulation and ingestion. It binds to the receptor at the voltage gate and causes inward Na+ flow thereby substituting cation. Its high exposure could lead to muscle paralysis and respiratory failure leading to death of clams
Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.
