Argon, which comprises almost 1 percent of the atmosphere, is approximately 27 times more abundant than CO2, but does not contribute to global warming. Which explanation accounts for this fact

Transparent to the wavelengths of light

Explanation:

Argon, an element comprises of almost 1 percent in the Earth’s atmosphere, is approximately 27 times more abundant than CO2, is not a greenhouse gas. The reason that it is not a greenhouse gas or not contribute in global warming is that it is largely transparent to the wavelengths of light that is responsible for trapping heat that is similar to that of oxygen, nitrogen and other gasesArgon is not able to form large and complex molecules that are enough to block infrared light, which is generally done by greenhouse gases such as carbon dioxide and methane also.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
