An experiment uses two groups of mice with 20 individuals in each group. both groups are fed the same amount of water and food every 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

constants.

Explanation:

Climate-controlled room are almost indoor and are kept with stable temperatures and also with stable humidity levels.

In biological experiments, it used to establish constant parameters like temperature, humidity, exposure to different things, growth of organisms and etc.

These rooms provide better shelf life and thus better results.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
