I beleve that they use them to test medicine and human vaccinations.
Scientists use control groups to show how something will change under normal circumstances.

Well scientists do study them but there isn't an actual name of the study of them.
yes gum is scientific. you can use it for expirements and if you look closer it has many ingredients

No, don't use crittertrail cages with gerbils. Unlike hamsters, gerbils are chewing machines. They can ingest the plastic which can kill them, and by chewing the plastic they can escape. I would use a 10 gallon tank instead. Gerbils cost around $10 each from a pet shop.

for my opinion, Mendel use plants in his experiments so that we can see clearly the characteristics and differences as a good example for cross pollination
They have to use standard units of measurements in their expirements, so they can commpare data
I believe that gerbils are best at smell, and maybe hearing. Gerbils use smell to tell each other apart and what things are, as their eyesight is not so good.
controlled expirements i think
