Today the white tailed squirrel is found on the North side of the canyon, and the gray tailed squirrel is found on the south side of the canyon. These squirrels cannot produce offspring together. When DNA from each type of squirrel is analyzed, the results indicate that the squirrels are very closely related. Based on this information, which inference can be made about the two populations of squirrels?The squirrels evolved from the same ancestors and are considered the same species.The squirrels evolved from the same ancestors but are considered different speciesThe ancestors but are considered the same squirrels evolved from different species.The squirrels evolved from different ancestors and are considered different species.Why are some biologists now using a six kingdom classification scale?Scientists have developed more advanced tools to study the physical and genetic structure of organisms.Scientists needed a new kingdom because all other kingdoms became fullScientists created species with unique traits through the process of genetic engineeringScientists have recognized organisms living in water are different from organisms living on land.Of the total amount of energy of a producer, how much energy is transferred to the 1st level consumer?100%90%50%10%KindomAnimal IAnimal IIAnimal IIIAnimal IVAnimal VFamilyChordataChordataChordataChordataChordataClassMammaliaMammaliaMammaliaMammaliaAmphibiaOrderCarnivoraCarnivoraCarnivoraPrimatesSalietiaFamilyFelidaeFelidaeCarnidaeHominidaeRanidaeGenusFelisFelisCanisHomoRanaSpeicesleodomesticusfamiliarissapiensclamitansIn the table above, the two animals showing the greatest similarities are:Animals I and IIAnimals II and IIIAnimals III and IVAnimals I and VDuring photosynthesis in plants, what is the source of the carbon in the sugar molecule (CH)?carbon dioxide in the aircarbon monoxide in the aircarbon particles in the soilcarbon particles in waterDarwin's ideas on evolution were not accepted by scientists in his time.
