In 2013, researchers constructed a vesicle with replicated RNA. Why was this significant evidence for abiotic origin of life? In 2013, researchers constructed a vesicle with replicated RNA. Why was this significant evidence for abiotic origin of life? a. RNA molecules could pass on information to their "daughters." b. RNA molecules were not able to replicate. c. RNA is a stable repository. d. RNA would be used up by protocells.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

What would be the result if crossing over did not happen during meiosis in humans? a. there would be less genetic variation in humans. b. parents would be more likely to look like their children. c. the human population could not reproduce. d. children would have more chromosomes.
