Question

17 multiple choice 4 points changes in one letter of dna (atcg) are called what type of mutation? point frameshift inversion translocation 18 multiple choice 4 points is the book published by darwin which explains his theory of natural selection and descent with modification. evolutionary change and the origin of the species on the evolution of species by natural selection on the origin of the species by natural selection the theory of natural selection through evolution 19 multiple choice 4 points which of the following is not a part of the theory of natural selection? individuals with beneficial traits survive to produce more offspring than those that do not possess beneficial traits. all organisms show natural genetic variations within their population. as beneficial traits become more common in a population, the population becomes less adapted to the environment than they were before. genetic variations are passed from parents to offspring via sexual reproduction.

Explanation:

1. A point - mutation is a change in a single nucleotide (one letter of DNA).
2. Darwin's book that explains natural selection and descent with modification is On the Origin of the Species by Natural Selection.
3. In natural selection, as beneficial traits become more common, the population becomes more adapted to the environment, not less.

Answer:

1. A. point
2. C. On the Origin of the Species by Natural Selection
3. C. As beneficial traits become more common in a population, the population becomes less adapted to the environment than they were before.
