Chapter 22, Problem 17TYK
Evolution by natural selection would be impossible in a population

Which of the following is NOT evidence for endosymbiosis?
A. Bacteria and mitochondria both have nuclei.
B. Bacteria and mitochondria both have ribosomes.
C. Bacteria and mitochondria both have circular DNA.
OD. Bacteria and mitochondria both reproduce via binary fission
E. Bacteria and mitochondria both have membranes.
Horizontal gene transfer probably started soon after endosymbiosis. It has resulted in genes being moved from the mitochondrion to the nucleus.
What is a reasonable explanation for why some genes still remain in the mitochondria?
A.
The products of those genes are rapidly damaged and need to be quickly replaced.
B.
The products of those genes are not required for organelle function.
C.
The ability for lateral gene transfer ended about a billion years ago and some genes simply got “stuck” within mitochondria.
D.
The products of those genes are only needed in the mitochondria.
Consider all of the species on earth. Some scientists believe that the genes for growth and reproduction have been under evolutionary forces for longer than those involved in maintenance and repair. Which statement below best supports their theory?
a. Most species die after producing offspring.
b. “Survival of the fittest” is true.
c. Most animal species mate for life.
d. Only the more intelligent organisms live long lives.

- The transfer of genes by a mechanism not involving asexual reproduction is called: a. meiosis b. web of life c. horizontal gene transfer d. gene fusionarrow_forwardSelect the statement that does NOT support the origin of excavates that lack plastids, have highly reduced mitochondria and are parasites: A. These parasites typically live in low-oxygen conditions and therefore loss of genes for plastids and mitochondria did not result in lower fitness B. The original, eukaryotic ancestors of these parasites did not engulf prokaryotes C. These parasites typically live in low-oxygen conditions, and many of their mitochondrial genes move to the nucleusarrow_forwardWhat is the most likely evolutionary advantage of sexual reproduction? a. Sexual reproduction is more efficient than asexual reproduction b. Sexual production minimizes adverse mutations c. Sexual reproduction is associated with faster recombination. d. Sexual reproduction leads to significant genetic recombination. e. Sexual recombination is associated with more numerous offspring Which of the following is unnecessary for adaptation? a. Replication b. Selection C. Time d. Competition e. Variationarrow_forward
- Over the past several decades, natural selection has caused populations of Staphylococcus aureus (an infectious wound bacterium) to evolve resistance to most antibiotics. If antibiotic use were stopped, what would you predict would happen to these S. aureus populations? A. Horizontal gene transfer would increase B. The populations will begin colonizing new environments. C. The frequency of resistant forms will definitely increase in these populations. D. They will go extinct without the antibiotic. E. The frequency of nonresistant forms will increase in these populations.arrow_forwardIt is said that sexual reproduction is selectively advantageous to asexual reproduciton. Why is the case? A. Asexual reproduction produces much more genetic diveristy than sexual reproduction B. Asexual repoduction is only half as efficient as sexual repdocution in sending ones genes into the next generation C. Sexual reproduction increases genetic diversity and consequently slows the rate of evolution D. Sexual reproduction is much faster than asexual repoduction E. Sexaul reproduction produces variation among populations which can help increase fitness for certain individuals/increase selection for favorable traitarrow_forwardSieve tubes and sieve elements are a. homoplastic because they have different function. b. homologous because they have similar function. c. homoplastic because their common ancestor was single-celled. d. structures involved in transport within animalsarrow_forward
- Which of the following alleles is most likely to increase in a population due to natural selection? A. An allele that prevents peptidoglycan synthesis B. An allele that causes a helminth to produce eggs more quickly C. An allele that creates a non-functional cytoskeleton D. An allele that prevents algae from capturing blue light in photosynthesisarrow_forwardA group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists? A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction. B. The animals could not adapt to the new environment. C. Bacteria lived in areas that were not affected by the zoning D. The animals became susceptible to human and environmental harm.arrow_forwardYou are examining an organism you believe to be an animal. Which of the following would NOT support your hypothesis? O A The organism appears to be heterotrophic. O B The organism appears to be multicellular. O C The organism appears to be motile. O D The organism appears to have cell walls. O E All animals, including sponges, have development directed by Hox genes.arrow_forward
