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.

After the unknown eradication of the Homo Neanderthals, Homo Sapiens became the only homonine for the last 24,000 years. That is to say, that modern humans are the result of the evolution of homo sapiens to homo sapiens sapiens.</span>
Answer:
What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:

So what would happen if there were no condensation stage?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.
Without clouds, I foresee a few things happening:
From clouds come rain. With no clouds, there would be no rain.
Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.
Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.
And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
