Why do some female rats turn into male rats?
Female rats don't just turn into male rats. Sometimes a male rat's testes will be withheld in his body as a result of stress and he will appear to be female. Of course in such a situation, he is still male.
What is the lifespan of Wistar rats?
Wistar rats appear to be an interesting model to study the changes related to metabolic syndrome. They can have a lifespan of two to three years.
Why are naked mole rats called naked mole rats?
Naked mole rats are called "naked" because they do not have hair or fur on their bodies, making their skin appear naked. They are called "mole rats" because they live underground, dig extensive tunnel systems like moles, and have physical characteristics similar to rats.
Can rats get hiccups?
Yes, rats can get the hiccups. Rats do not have a gag reflex, which prevents them from burping, vomiting etc. Hiccups, however, are the result of a muscle spasm in the diaphragm. Rat hiccups are silent. Your rat may sit still and appear to be twitching much in the same way that humans hiccup.
Where did the black death appear?
I think it originated from the east maybe china and then spread to Europe via ships carrying rats with fleas.

Yes, in part. But also, rats are darker in both hair color and eye color, which makes them appear dirty. Rats have also been known to attack when cornered, and spread more diseases (like bubonic plague) than mice.
When was the first rat born?

Are rats invertebrate?
No, rats are vertebrates. Rats have backbones.
What does a psychologist mean when she says a particular experimental result results is significant?
In science (and possibly in psychology as well), "significant" has a special meaning, which is that two things appear to be correlated more than one would expect from random chance.If, for example, we have a lot of lab rats, and we play Justin Bieber at half of them and Frank Sinatra at the other half, and all the Bieber rats turn out to be homosexual and none of the Sinatra rats do, that's significant. If we only have a few rats, or if some of the Bieber rats and some of the Sinatra rats are homosexual, then maybe it's significant and maybe it's not; there are mathematical tests you can do to say with varying levels of confidence "Justin Bieber turns rats homosexual."
