Scientists use squid nerve cells in research because the nerve cells of a squid are 1,000 times fatter than those of a human. how is the outcome of nerve cell research most likely to be affected if scientists were to study human nerve cells directly? the outcome would be different because humans and squids are very different. the outcome would be different because the nerve cells in squids are much larger than those of humans. the outcome would be the same because in both cases a nerve cell is being researched. the outcome would be the same because genes in squids and humans are 85 percent identical.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
