Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.

Answer:
D.
Explanation:
Plants take in CO2 and turn into Carbo.
That's the most efficient example
Hey there
the answer is
a Archean is a single celled microorganism and has no cell nucleus
and Bacteria <span>constitute a large </span>domain<span> of </span>prokaryotic microorganisms<span>. Typically a few </span>micrometres<span> in length, bacteria have a </span>number of shapes<span>, ranging from </span>spheres<span> to </span>rods<span> and </span><span>spirals</span>
so im going to say D as the answer
Hopes this helps u :)
<span>The roots of plants are able to self-regulate the amount of water they take in. Therefore, by adding this amount of water, Stela is insuring that the plant will have as much water as it needs to grow. </span>
