Answer:
A mutation during protein synthesis may not affect the protein since the mutation causes a new code for the same amino acid, the protein will still function normally.
Explanation:
Protein synthesis depends on the transcription of DNA to RNA, and on the sequence of nucleotides in the chain, determining the triplets or codons that encode a specific amino acid.
In protein synthesis, when a mutation alters the codon, changing one nucleotide for another, it is possible that the mutation does not alter the amino acid and the protein functions correctly. This is because an amino acid can be encoded by several codons, as occurs with leucine, which is encoded by CUU, CUC, CUA and CUG.
<em> The other options are not correct because one mutation does not give better amino acids or more powerful proteins.</em>
Example: Darwin’s Finches
In evolutionary biology, adaptive radiation is a process in which organisms rapidly diversify from ancient species to a wide range of new forms, in particular when environmental changes provide for new resources, create new challenges or open new niches to the environment.
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
