The genetic code is redundant. The meaning of this statement is that (D) More than one codon can specify the addition of the same amino acid.
Genetic code is a set of three nucleotides (mRNAs) that code for an amino acid together. The concept of given by Francis Crick. These codes are standard in majority of the organisms on Earth, hence the code is universal. For example, UGG codes for tryptophan.
Amino acids are the molecules that are involved in the formation of proteins. They have an amino group as well as a carboxylic group attached to the same alpha-carbon. There are 22 amino acids in the body that are involved in protein synthesis.

Fossils, or preserved parts of organisms from the distant past, have shown that species change over time. Radiometric dating can be used to determine the age of fossils by measuring the how much of the radioactive materials in each rock layer have broken down.
Answer:
Codominance is when both alleles in the genotype are seen in the phenotype, like a flower that is half blue and half red. Incomplete dominance is a mixture of the alleles, like for example, a mixture of blue and red flower, a purple flower.
Answer:
C. Both light tan and dark tan body color provided an advantage to the crabs on this beach, but not necessarily in other crab habitats.
Explanation:
The changes in the number of light tan and dark tan body color of crabs that occured can be described as a diversifying or disruptive selection.
This disruptive selection occurs when individuals with extreme traits on both ends of the spectrum become selected against individuals of ntermediate or medium traits.
In the case of the crab, their environment favors the selection of both extreme values as against those intermediate individuals, as both light tan and dark tan body color of the crabs gives them advantage over others in this particular environment. This may only be obtainable in this environment or similar beach environment with the same settings and conditions.
