One feature of rats that make them a good experimental model to learn about factors that affect humans are they are small and familiar. Another factor is that they are easily bred for experiments.
Scientists experiment with rats for many reasons. A rat's digestive system and organs are very closely like humans. They use rats to learn more about humans.

No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
The rats in NIMH were forced to participate in the experiments for approximately 10 years before their intelligence was enhanced.

Lab rats helps us by using them to do dangerous experiments. That way we don't have to do it on humans.
Nicodemus and the other rats were forced to participate in the experiments for a period of about a year before they managed to escape from the laboratory.
Yes Dr. Christiaan Barnard did perform his first experiments on 50 dogs 35 cats and some rats.
There are various different experiements performed on rats, & they quite often vary between male & female results. Male rats are not a high choice for experiments, but should a test to be used for men need to be created, then male rats would be the test subjects, & vice versa for females/
Pet rats are not vermin. Pet rats are raised in a pet store, laboratory, or adoption center and they are raised to be pets or in the case of labs, experiments. if you are thinking of buying a rat remember not to buy a rat raised as food for snakes. Rats bred to be pets are much gentler and sweeter than rats raised as food.
The question was ,"What substance was responsible for transformation?" psst. it was DNA, (:
they are more commonly born in a litter then multi-colored so there for they are cheeper so if the experiment fails and the rat dies they don't lose money! poor rats :(
For brain or drugs experiments, rats are frequently used but dogs and monkey are also used a lot.
Selye used rats in experiments with hormones but as an aside discoverd thet rats were more harmed by the shock of the injections than the hormones. selye developed his GAS or general adaptation syndrome.
In the 1970s, Ader performed experiments on lab rats, which showed that environmental factors could impact the immune system.
