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.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
