The respective percentages of nitrogen, oxygen and argon in the atmosphere are<em> 78.1%, 20.9% and 0.934%.</em> The process that produce trace gases is called source and the process that removes trace gas from the <em>atmosphere is called sink.
</em>
<em>Some other examples of trace gases are carbon dioxide, neon, helium etc.

Answer:
The calcium-binding protein in smooth muscle is __calmodulin_____; while the calcium binding protein in skeletal muscle is _troponin_____.
Explanation:
