2. What process do mRNA and tRNA work together to complete? (3 points)
liberstina [14]

This process occurs in the ribosomes. As the ribosome reads the codons on the mRNA the corresponding tRNA with the complementary anticodon is recruited. The tRNA brings in an amino acid (attached to it), and the amino acid is joined to the rest of the growing  polypeptide chain. Each codon/anticodon specifies for a specific amino acid.

The biosphere is made of different kinds of matter. Which substance is an
Sedaia [141]

Salt is the Inorganic matter.

Option D.

<h3><u>Explanation:</u></h3>

Organic matters are defined as those compounds of carbon expect the carbonates, bicarbonates, cyanides etc. These compounds were primarily thought to be produced only from the living organisms and were unable to be produced in laboratory. But later they were being produced in laboratory too.

Inorganic compounds are all the compounds except the organic ones.

Here, in the question, we see the compounds -

Protein - it's the polymer of amino acids which contain carbon, and isn't carbonates or bicarbonates, cyanides etc.

Carbohydrates and sugars are also similar to proteins which contain carbon and isn't the exceptions. So they are also the organic compounds.

But salt, commonly table salt is sodium chloride which doesn't contain carbon, so is Inorganic.
