Adaptations are defined as the components of an organism that benefit survival and reproduction. Adaptations born from natural selection. The mutations that leads to natural selection are random. These random mutations allows the organism to survive under a determined environment and reproduce.

6. One class of tool molecules built by biological organisms that we discussed are "catalysts." Which of the following is the most accurate and complete statement about such biogenic catalysts? a. Biogenic catalysts allow reactions that could never occur (even occasionally) in their absence; thus, biological chemistry is qualitatively different than all non-biological chemistry. b. Biogenic catalysts dramatically accelerate a tiny subset of all possible chemical reactions that specifically serve the replication of the organism's design information; biological chemistry is,...

Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...

Which of the following statements is accurate, at least according to our present knowledge? a. Prokaryotes acquired genes from fungi; now, all prokaryotes can digest cellulose. b. Prokaryotes acquired genes from eukaryotes many times; the reverse has never happened. c. Genes from prokaryotes have been acquired by some eukaryotes. d. Eukaryotes acquired nuclear genes; these genes allow survival in anaerobic environments. QUESTION 10 Which of the following statements about horizontal gene transfer is accurate? O a. Horizontal gene transfer among...
