Dna is the genetic material that makes up living things, and folic acid plays an important role in the formation of dna. jon wants to study the effect of folic acid on dna formation in microbes. which statement accurately describe the variables in this study? a. the amount of folic acid and dna synthesized are both dependent variables. b. the amount of folic acid and dna synthesized are both independent variables. c. the amount of folic acid is the independent variable, and the dna synthesized is the dependent variable. d. the amount of folic acid is the dependent variable, and the dna synthesized is the independent variable. e. the amount of folic acid and dna synthesized are neither dependent nor independent variables.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
