An experiment uses two groups of mice with 20 individuals in each group. Both groups are fed the same amount of water and food e
very day. They are kept in similar cages in a climate-controlled room. The experimental group is given five doses of a pesticide every day. After two months, the amount of an enzyme in the brains of the mice was measured. Use Passage 1-2. The climate-controlled room is important to establish _______.
Climate-controlled room are almost indoor and are kept with stable temperatures and also with stable humidity levels.
<u>In biological experiments, it used to establish constant parameters like temperature, humidity, exposure to different things, growth of organisms and etc.</u>
These rooms provide better shelf life and thus better results.
