No its not illegal,scientists carry out multiple tests.
The laboratory experiment involves a total of 20 mice.
Its illegal to catch mice in Cleveland Ohio if you do not have a hunting license.
it is not illegal, why would it be illegal in the first place?
only in Alaska
yes
the experiment could be repeated with the same mice
Exhaustion phase
Only the fancy ones (unless feeding it to a snake, that would be fine). HOWEVER, killing a house mice is not illegal, and therefore should be killed.
Because it is needed.
In the Proteus experiment involving laboratory mice, the variable parameter was likely the specific conditions or treatments applied to the mice, such as dietary changes, environmental factors, or genetic modifications. These variables were manipulated to observe their effects on the mice's behavior, physiology, or overall health. By altering these parameters, researchers aimed to identify causal relationships and better understand the underlying biological mechanisms.
no its not because it they are awesome pets to have.
Test animals to experiment on. (dissecting trying new product, etc.)
