Why do medical researchers use rats. Why rats? Physiology The size of body sciences and rats - they are easy to handle and small enough for the home - the main reasons for their popularity in the laboratory. In 2013, laboratories in Canada used 1.2 million mice in research according to the Cabinet for Animal Care in Canada, according to the National Body, which oversees strict rules around health and welfare for all laboratory species. Why rats? Stable Scientists are always looking for alternatives to animal use in clinical research, but the role of rats in the form of experimental models for human disease is still immutable. Even with the difference between the two species, basic research in the manual mouse model of the disease gives valuable information to the scientists. Using rats in the form of surrogates, researchers are allowed to see how patients can respond to treatment before giving them medication - an important step in ensuring patient safety.

Floating body on water There are many bacteria in our body area (meat intestines) in our body. When a whole body goes inside the water or dies inside the water then our lungs which are initially filled with air, are filled with water. Along with this, the bacteria that were first made about earlier were starting to produce various gases, for example "methane gas, carbon dioxide". Due to this kind of gases produced, our body density is decreasing and our bodies are starting to work like billions filled with gases and as we know, if the density of the water is high then any body on the body Floating starts. This is the reason for the floating body found in water.
