Question 1

what is the change of heritable characteristics in a species over multiple generations through the process of natural selection?

Answer 1

evolution

Question 2

what drives evolution when certain environmental factors cause differences in the reproductive success of individuals with particular genotypes?

Answer 2

natural selection

Question 3

what must be present for natural selection to occur?

Answer 3

preexisting genetic variation, natural selection does not create the variation it just impacts it.

Question 4

what is the major source of genetic variation in bacteria?

Answer 4

mutation

Question 5

what introduces genetic variation through the direct transfer of DNA from one bacterium to another?

Answer 5

conjugation

Question 6

what is the transfer of DNA to bacteria by bacteriophage viruses?

Answer 6

transduction

Question 7

what is the the uptake of DNA from the environment into bacterial cells?

Answer 7

transformation

Question 8

what is the antibiotic that can be used to kill bacteria by inhibiting protein synthesis, but bacteria can develop resistance to it?

Answer 8

streptomycin

Question 9

what describes how large populations do not experience changes in allele and genotype frequencies unless the population is being influenced by agents of evolution?

Answer 9

The Hardy-Weinberg law of equilibrium

Question 10

what use the same genetic code?

Answer 10

living organisms

Question 11

what gives instructions that allow cells to produce necessary proteins?

Answer 11

genetic code

Question 12

what do proteins evolve through?

Answer 12

amino acid substitutions(mutations)

Question 13

what uses serum proteins of interest attached to a plastic well?

Answer 13

the enzyme linked immunosorbent assay (ELISA)

Question 14

what is the binding of multiple antigens by a single antibody, resulting in a complex that can be seen by the naked eye?

Answer 14

agglutination
