Question

5 multiple choice 1 point a heritable trait that confers on an individual a survival and reproduction advantage in its current environment is called what? a transposable element an adaptation a translocation a mutation 6 multiple choice 1 point a scientist compares a gene from yeast to a similar gene found in humans and discovers that they look very much the same. these data could be interpreted as all of the genes in yeast and humans must code for the same products. evidence for a common creator evidence for a common ancestor or a common creator; the data fit either paradigm. evidence for a single common ancestor 7 multiple choice 1 point antibiotic resistance in bacteria is an example of natural selection allopatric speciation migration genetic drift 8 multiple choice 1 point individual differences with a genetic basis lead to ____ in successive generations. extinction normalization speciation variation

Explanation:

• Question 5: An adaptation is a heritable trait that gives an organism a survival and reproduction advantage in its environment. A transposable element is a DNA sequence that can change its position in the genome. A translocation is a chromosome abnormality. A mutation is a change in the DNA sequence.
• Question 6: Similar genes in yeast and humans could be due to a common ancestor (evolutionary view) or a common creator (creationist view). The data fit either paradigm. Just because one gene is similar doesn't mean all genes code for the same products. And it's not just evidence for a single common ancestor as creationist view is also a possibility.
• Question 7: Antibiotic resistance in bacteria is an example of natural selection. Bacteria with resistance genes survive antibiotic exposure and reproduce. Allopatric speciation is speciation due to geographic isolation. Migration is movement of organisms. Genetic drift is random change in allele frequencies.
• Question 8: Individual differences with a genetic basis lead to variation in successive generations. Extinction is the dying out of a species. Normalization is a statistical or data - related term. Speciation is the formation of new species.

Answer:

• Question 5: B. an adaptation
• Question 6: C. Evidence for a common ancestor or a common creator; the data fit either paradigm
• Question 7: A. natural selection
• Question 8: D. variation
