Scientists use squid nerve cells in research because the nerve cells of a squid are 1,000 times fatter than those of a human. 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 ide

$\sf\color{green}{ >1,000 ~times~ fatter}$
$\sf \color{green}{>fatter}$

"fatter" is not a characteristic of a cell..is this a real question from your school? who write this? lol They mean "wider" or "larger diameter". 

Anyway, the correct answer depends on what the research is..  "The outcome would be different because the nerve cells in squids are much larger than those of humans." could be a possible answer because larger nerve cells can transmit the electrochemical message faster. But both nerve cells work on the same principles so it could also be "The outcome would be the same because in both cases a nerve cell is being researched.".

There is not definitive answer unless the type of research is specified.
