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
