- You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * O Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. O Microevolution is occurring in both variations. O They are two separate species.For the following question, first, explain if it is true or false. If false correct the underlined word to make it true. If you do not correct it then you will lose all points. Sea Lamprey has gills that are little holes while most fish have gills that are slights that filter the water, this is an example of a(n) analogous structure. O True O False: Homologous O False: Vestigial organ O False: coevolutionScientists 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
- Similar gill pouches in embryos of a chick, human, and cat are an example of genetic homology O structural homology the inheritance of acquired characters O developmental homologyA researcher studying the wing structures of bats, birds, and insects finds that while they all have wings, their underlying bone structures and development are different. The wings of these organisms are examples of: Homoplasy Homology Synapomorphy ApomorphyHow can biologists explain similar gill pouches in embryos of a chick, human, and cat? O genetic homology developmental homology the inheritance of acquired characters O structural homology
- Lepidoptera caterpillars differ from sawfly caterpillars by having more prolegs by having parthenogenesis in many species |by having a pair of stemmata rather than multiple stemmata on each side by being crochets on their feet in movement through looping for some familyThe evolution of wings helped the insect clade to be very successful. In this example, wings are an _______. a. derived trait c. key innovation b. adaptive trait d. all of the aboveWhich of the following is an animal characteristic that also is a synapomorphy supporting animal monophyly. O Sexual reproduction O Multicellularity O heterotrophy O muscle tissue
- Some organisms have features that have different functions, but similar structures. One example is the forelimb of humans, dogs, birds, and whales. Human Dog Bird Whale What term best describes the relationship between these forelimbs? They are vestigial. O They are homologous. They are embryological. They are analogous.What must be TRUE of any organ described as vestigial? It need be neither homologous nor analogous to some feature in an ancestor. O It must be analogous to some feature in an ancestor. O It must be homologous to some feature in an ancestor. OIt must be both homologous and analogous to some feature in an ancestor.Which of the following is probably the best explanation for the fact that Antarctic penguins cannot fly, although there is evidence that millions of years ago their ancestors could do so? Group of answer choices Penguins live on land and feed in the water; therefore they have no need to fly. The Antarctic home of penguins is flat and barren; therefore there is no place to fly. Ancestral penguins did not use their wings for long periods of time; therefore today’s penguins have only tiny, nonfunctional wings. Ancestral penguins without large wings were better able to swim and feed in the water; therefore they passed their genes for shorter wings structure onto their offspring.
