Explanation:
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
Answer:
d) genetic drift
Explanation:
The ABO and MN blood-type frequencies of the Dunkers differ significantly from those of current American and German populations due to Genetic Drift. This term refers to variation in the relative frequency of the different genotypes that may exist within a small population, which results in the extinction of different genes as individuals die without reproducing.
Answer:
Purpose research is the statement or sentences that describe the main reason or why the study is been conducted or why the research is been conducted.
Avoiding bias refers to the act the authors avoid using language that are biased or not factual
Explanation:
Purpose research is the statement or sentences that describe the main reason or why the study is been conducted or why the research is been conducted. It states the goal of the study .
Avoiding bias refers to the act the authors avoid using language that are biased or not factual information that portray the evidence.
Hypothesis experiment refers to information or explanation that is supplied which can be tested to be truth or falsifiable.
Independent variable is a variable that can stand alone and it's variation does not depend on another but the experimenter can control or change it in an experiment.
Dependent variable is a variable that cannot stand alone but depends on independent variable in an experiment.
Control analysis refers to analysis that supply information about the output, the approaches or method used.
Conclusion refers to the final statements or words to finish a discussion or experimental study.
Answer:D
Explanation:Life started in the oceans so others dont make sense
Operons are gene regulatory mechanisms that involve promoting and repressing genes that are involved in the metabolism of organic substances (i.e. sugars). Living organisms have the innate ability to metabolize glucose as the main source of energy. Although, in the absence of glucose, the organism must "learn" to use sugars other than glucose (such as lactose) in order to survive.
For instance, in the <em>lac </em>operon:
In the absence of glucose, various regulatory proteins promote the transcription of the gene related to the metabolism of lactose. This will ultimately lead to the production of the enzyme beta lactosidase which will enable the organism to use lactose as energy in the absence of glucose. This will therefore increase the chances of the organism for survival and will be naturally selected for evolution.
