Scientists use various methods to determine how closely two species are related. One method is to compare their physical features, and another is to compare their DNA. Can scientists also use similarities in the embyros of two animal species to help determine how closely they are related? No, comparing embryos of organisms does not help determine how closely two species are related. Scientists can obtain the same information comparing adult organisms No, comparing embryos of organisms does not help determine how closely two species are related. The embryos change too much as they grow into adult organisms Yes, comparing embryos is a useful way of determining how closely two species are related. There may be important similarities in the features of the embryos, even when the adults look very different. Yes, it is sometimes useful to compare embryos, but only when the adults are very similar

A phylogenetic tree represents...  a hypothesis about evolutionary relationships a branch point for species Binomial nomenclature Relationship between sister taxa Breakdown between large groups like kingdoms and small groups like species

As an evolutionary biologist, you are asked to determine whether if two different populations of scavenger beetles that occupy different adjacent habitats are a single species or two distinct species. Which species concept would give you the best tool to determine this? Biological Species Concept Morphospecies Concept Phylogenetic Concept Ecological Species Concept

A scientist is studying two different species of fish. The table below shows various observa- tions that the scientist could have seen in the two different species of fish. Observation Number A B с 1 D 2 3 4 observation 1 observation 2 observation 3 Genetic Similarity observation 4 high low low high Function of Structure different same Which observation number would best support the claim that the two species have structural similarities, specifically as a result of convergent evolution? different same Form of Structure same different same different

A- the two nematode populations have undergone complete speciation B-  individuals reared on different bacteria produce offspring that have a better chance of survival C- The populations appear to be most likely in the process of speciation D- all individuals were equally reproductively successful regardless of mate combination

Which of the following is/are true? Group of answer choices All animal species are diploblastic. All animals are multicellular. All animal species are autotrophic. All animal species are radially symmetrical. None of the answers shown are true.

Figure 4. This map shows the range of five different bird species in North America based on data collected from 1980 to 1995.  For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above.  Fossil evidence suggests that Bird F and Bird X once shared a common ancestor that predates the formation of the mountains that separate them. This evidence is consistent with vicariance in these two species.    Question 13 options:   True   False

In another class, you and a classmate are peer reviewing each others' papers to check for plagiarism. You compare a passage from your classmate's paper to a section from an article that they used for their research.   Article passage:   Birdwing butterflies are found in Oceania and Southeast Asia and can reach wingspans of almost 9 inches. They are so large and high flying that some researchers had to shoot them out of the sky with rifles in order to collect specimens. Unfortunately, these big, beautiful butterflies are endangered due to habitat loss and the illegal butterfly trade.   Classmate's passage:   One of the most beautiful groups of insects found in Southeast Asia is the birdwing butterfly. There are many species of birdwing butterfly found in Southeast Asia, and unfortunately these big, beautiful, insects are endangered due to habitat loss and the illegal butterfly trade. Birdwing butterflies are the largest butterflies in the world, with some species growing up to 9 inches…

What is a reason that speciation can occur?         Organisms within a species are brought into closer proximity by a physical barrier.         Organisms within an ecosystem make adaptions that involve different breeding times or interactions.          Organisms develop traits that are not beneficial to their survival, and these traits are passed from generation to generation.         Organisms develop traits that are beneficial and pass on the same traits to all future generations within the same species.
