Spirochete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. D. Spirochete DNA is linear.arrow_forwardTwo different plants, cactus from the desert southwest USA and a euphorb from South Africa, have similar adaptations to desert life- these similarities evolved independently in response to similar environmental conditions, they were not inherited for one shared ancestor of cactus and euphords . What is the best term for these adaptations? A. Synapomorphies B. Acclimations C. Homologous traits D. Analogous traitsarrow_forwardWhy can’t scientists just do DNA analysis on these fossil hominins to determine if they are a separate species and possibly what species they belong to? A. The DNA of fossil hominins is too similar to modern humans, making it difficult to distinguish between them. B. The technology for extracting DNA from fossils hasn't been developed yet. C. The fossils would need to be in a -5 degree Celsius environment to prevent DNA from degrading D. Scientists can't perform DNA analysis on fossil hominins because the fossils have been contaminated with modern human DNA over the years, making it impossible to isolate the ancient genetic material.arrow_forward
- Some species undergo polyploidy, which is a multiplication of their chromosomes. That is, they contain full chromosomes from each parent. How could speciation affect a polyploid organism? A. The polyploid organisms may experience gametic isolation. B. The polyploid organisms may experience behavioral isolation. C. The polyploid organisms may experience geographic isolation. D. The polyploid organisms would not be affected by speciation.arrow_forwardAccording to "The Complex Evolution of Homo sapiens", what is the significance of the L3 gene and who was the L3 woman? A.Only individuals within North and South America descended from the L3 woman. B.All individuals within Africa are descended from the L3 woman. C.All individuals outside of Africa and who live in the Old World are descended from the L3 woman. D.All individuals outside of Africa are descended from the L3 womanarrow_forwardIn this data table comparing DNA sequences among various protists, why do some cells have a dash rather than a value? A. Those cells would compare one species to itself. B. Those cells would duplicate comparisons shown elsewhere in the matrix. C. Those comparisons were not made by the researchers.arrow_forward
- which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forwardThe three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.arrow_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
