This shows that recessive alleles are not always eliminated by natural selection.

<h3>Natural selection: what is it?</h3>
  • One method of evolution is natural selection.
  • More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.
  • Natural selection, which occurs over time as heritable features that aid organisms in surviving and reproducing grow more prevalent in a population, was another process Darwin proposed for evolution.
<h3>What variables influence natural selection?</h3>

Reproduction, heredity, variation in organism fitness, and diversity in individual traits among population members are the four prerequisites for natural selection to take place.

​If Clark had no ions in his nervous system, ____. ​his action potentials would be faster ​his action potentials would be slower
telo118 [61]

Answer:

If Clark had no ions in his nervous system, he would not be able to generate an action potentials.

Explanation:

An action potential occurs when a stimulus causes sodium channels to open in a neuron. Sodium floods in, making the inside of the cell more negative and the outside more positive. This is known as depolarization. Then, the Potassium channels open to allow Potassium out (Repolarization). A few too many K+ ions will leave the cell (Hyperpolarization), and finally, the Sodium-Potassium pump will bring the cell back to resting potential.

As you can see, the Sodium and Potassium ions are <em>essential</em> to action potentials in the nervous system. If Clark had no ions in his system, he would not be able to send any action potentials at all.
