<h2>Answer:</h2>

The air we inhale is a <u>A) gaseous solution</u>.  

<h2>Explanation:</h2>

The air we breathe for our survival is the mixture of numerous gases comprising the atmosphere of the Earth. Argon, Nitrogen, Helium, Neon, Oxygen, Hydrogen, Nitrous Oxide, etc., are some of the gaseous solutions present on our planet. The gaseous solutions are not even classified as solutions rather they are addressed as mixtures.

For example, the carbon dioxide and oxygen gases are dissolved in nitrogen gas.  In gases, we cannot different the solute and the solvent with the naked eyes but we need to use some chemical methods for it.

The genetic code is redundant. What is meant by this statement?
storchak [24]

Answer:

This means that one amino acid can be coded by more that one codon.

Explanation:

A triplet code that code for an amino acid during translation is called genetic code. The genetic code is said to be redundant because a single amino acid can be coded by more that one triplet codon.  

So there can be synonymous codon for one amino acid. For example, leucine, serine, and arginine have 6 synonymous codons.

The genetic code is unambiguous also because each triplet codon can only code for a particular single amino acid. Genetic code is also universal which means the same code is used in all life forms.
