Species is most closely related to 1ancestral primate 2chimpanzee 3gorilla 4orangutan 12The diagram below shows a comparison of nitrogen base sequences in the DNA of some organisms to those of a human.

. Parallel evolution occurs when two independent species evolve together at the same time in the same ecospace and acquire similar characteristics. Species A is the common ancestor of all life on Earth. Although the two species are not at all closely related they may appear quite similar as a result of ANSWER.

A The two species live at great distance from each other. This similarity is that the. In contrast relatedness between different species is 0 to about 65 percent.

Ruddy duck and white headed duckmany plant speciessome species always. A Both are cocci. The two species coexist successfully because Ahave different food requirements.

In the early stages of development the embryos of dogs pigs and humans resemble one another. This conclusion would be reasonable if the scientist observed that-. Many studies indicate that a bacterial species is composed of strains that are 70 to 100 percent related.

1 pig and the human occupy the same habitat while the fish occupies a different habitat. B The two species share many proteins in common and the nucleotide sequences that code for these proteins are almost identical. Species found in which taxonomic level are the most closely related.

Aeach occupies a different niche Bthey interbreed Cthey use different methods of reproduction Dbirds compete for food 2Two closely related species of birds live in the same tree. For example scientists can use DNA sequences to help determine if they have discovered a new species. A study of the embryos of a red squirrel an owl and a beaver showed that the beaver and the red squirrel appear to be most closely related.

The diagram below illustrates possible evolutionary pathways of some species. According to this cladogram primates are most closely related to -. D Both normally live in clams.

Scientists have been able to use _____to find common proteins and amino acids to determine how closely related species are. The more similar the junk DNA the more recent the split. D Both species are well adapted to their particular environments.

Pipistrelle bat in Britainsome pairs of species are different but can interbreed eg. BThe fossil record provides samples of every organism that ever lived. DFew organisms survive when the environment remains the same.

C Their DNA can hybridize together. Species B is the ancestor of species F. Up to 24 cash back a species is a group of organisms with similar characteristics which can interbreed and produce fertile offspringsibling species may show similar characteristics but cannot interbreed eg.

According to this diagram humans may be most closely related to the 1lead to mutations in the parent organism 2are always harmful to the offspring. We analyzed more than 1300 closely related species to test whether this correlation is generally applicable. Thus a CBC in an ITS2 sequence-structure alignment is a sufficient condition to distinguish even closely related species.

B Both ferment lactose. The kinds of evidence that indicates how closely species are related are evidence of DNA and protein structure. The optimal temperature for DNA reassociation is 25 to 30C below the temperature at which native double-stranded DNA denatures into single strands.

2Early stages in the embryo of a fish are similar to the early stages of human and pig embryos. C The structures in adult members of both species are similar in size. AF BG CH DK 20The diagram indicates that a common ancestor for species C and E is species AA and E BC and D CE and J DB and F 21Which species are least likely to be vital parts of a present-day ecosystem.

Animals that look alike are most closely related. 9 Questions Show answers. To play this quiz please finish editing it.

Two organisms that are closely related would have. Geographic separation led to divergence in the gene pool resulting in a new species in each location. CPopulations that have advantageous characteristics will increase in number.

2 pig and the human are more closely related to each other than to the fish. E Both are motile. 19Explain why species B and C are more closely related than species A and C are.

Scientists can also compare DNA sequences from different organisms and measure the number of changes mutations between them to infer if species are closely or distantly related. Species A feeds on ants and termites while species B feeds on caterpillars. And the numbers of DNA pairs involved are vast - theres no realistic way two species with reasonably large genomes could come to have similar junk DNA by chance.

How Can Scientists Tell How Closely Related Two Organisms Are. Different mating seasons led to the divergence of the gene pool resulting in a new species at each location. Different species can interbreed.

The beaver embryo looked most similiar to the owl embryo. 44 Which of the following characteristics indicates that two organisms are closely related. Species is most closely related to AGenetic alterations occur every time cell reproduction occurs.

This observation suggests that these animals may have. Two plant species live in the same biome but on different continents. In 93 where a CBC was found between organisms classified within the same genus they belong to different species.

Which statement is a valid inference based on the information in the diagram. The frog species occupied different habitats within the same geographic areas resulting in new species. Therefore if two species do have similar junk DNA it means they are quite closely related and parted company fairly recently.
