C. Mutations, this allows them to adept to their surroundings.
Unit cell: The simplest arrangement of atoms or molecules that regularly repeat in a crystal structure
Crystal lattice: A crystal lattice is a three dimensional atomic structure for the solid phase of matter.
Characteristics of a crystal lattice include
Symmetrical and infinitely repeating arrangement of atoms
hope this helps
Answer:
Early geneticists wondered how only four nucleotides could specify the sequence of 20 amino acids in proteins. Today we know that there is a genetic code in which <u>3</u> nucleotide(s) code(s) for each amino acid.
Explanation:
64 or 43 is the number of possible 3-letter codes which is more than the number of amino acids. Hence, the code can thus be redundant. It has been seen that there is more than one codon that codes for the same amino acid in some cases, .

There legs had to adapt to their new surroundings in order to survive so as time passed they evolved. I think it’s called natural selection.
