Marsupials, such as kangaroos, koalas, and wombats, are mammals that care for their newborn young in a pouch. all marsupials that are found in australia are thought to have evolved from a single species that migrated to the island and then adapted to the various niches. what does this example illustrate? behavioral adaptation adaptive radiation geographic isolation population explosion

When a new species form by geographic isolation, it is called geographical speciation or allopatric speciation. Geographical isolation is a physical separation which prevents gene flow between distinct populations (on the island and on continent). The island populations will eventually diverge from a single species that migrated to the island. The members of the populations, which once belonged to the same species, will no longer be able to mate and produce offspring. Eventually, the formation of new species will occur, for example kangaroos, koala, and wombats, form that one species.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .
