The thyroidectomized rat lacked thyroxine hormone. Activity 2 What was the effect of thyroxine on the normal rat’s metabolic rate? How does it compare to the normal rat’s baseline metabolic rate? Thyroxine caused the metabolic rate to increase; it was faster. Why was this effect seen? Because it stimulates heart rate‚

depression in teenagers. This article really discovers the effects of cannabinoids on rats which have had a prolonged exposure to CUS. The colleagues tested Long-Evans rats who were 70 days old with an independent variable as the amount of cannabinoids used on a CUS induced rat and the dependent variable as the amount of depression the rats had. A main method the researchers used to analyze the depression in rats was their sexual activity. All the behavioral testing was performed during the middle

GM maize‚ health and the Séralini affair Smelling a rat GENETICALLY modified maize causes cancer: that was the gist of a study‚ among the most controversial in recent memory‚ published in September 2012 in the journal‚ Food and Chemical Toxicology. Well‚ actually‚ it doesn’t. The journal has just retracted the article. It would be too much to say that GM foods have therefore been proven safe. But no other study has so far found significant health risks in mammals as a result of eating GM foods

reaction of the brain to ionizing radiation in a series of experiments on laboratory animals‚ mainly rats. Garcia noticed that rats avoided drinking water from plastic bottles when in radiation chambers. He suspected that the rats associated the “plastic tasting” water with the sickness that radiation triggers. During the experiments rats were given one taste‚ sight‚ sound as a neutral stimulus. Later the rats would be exposed to radiation or drugs (the unconditioned stimulus)‚ which would make the
