Answer:- Furthermore, almost all human genes known to be associated with diseases have counterparts in the rat genome and appear highly conserved through mammalian evolution, confirming that the rat is an excellent model for many areas of medical research.

Answer:- The use of animal models allows researchers to investigate disease states in ways which would be inaccessible in a human patient, performing procedures on the non-human animal that imply a level of harm that would not be considered ethical to inflict on a human.

Answer:- To improve our understanding of biology. That means we can study how bodies work by running experiments in animals that would be impossible in human volunteers, and this is where most research animals are used. Studying how healthy bodies function often reveals what is happening when things go wrong.

Answer:- Pros & Cons of Animal Testing Pro: Life-Saving Medications and Vaccines. The landscape of modern medicine would unquestionably be vastly different without animal testing in the mix. ... Con: Inhumane Treatment in Animal Experimentation. ... Pro: Similarity to Humans. ... Con: Lack of Applicability. ... Alternatives to Animal Testing.

Answer:- Animals are typically killed once an experiment is over so that their tissues and organs can be examined, although it is not unusual for animals to be used in multiple experiments over many years. There are no accurate statistics available on how many animals are killed in laboratories every year.

Answer:- While some animals may be used again, or sometimes even adopted out, most animals are humanely euthanized. This is usually because certain information, such as organ samples, can only be taken after the animal is euthanized and the body subjected to further analysis.

Answer:- Predators are essential to ecosystems because they regulate prey populations. Without predators, prey can become over-abundant. This can result in damage to local plants, as well as disease outbreaks that can spread to domesticated animals.

Answer:- With no predators to control the population and alter feeding behavior, the prey species quickly degrade and over-run its habitat. As food becomes scarce, the population becomes sick and malnourished, and will either move or crash.

Answer:- Dogs feel pain for many of the same reasons as humans: infections, dental problems, arthritis, bone disease and cancer. They also feel discomfort following surgical procedures. Unfortunately, unlike humans, they are unable to speak to us about when and where they hurt.

Answer:- Whats the average IQ of a mouse? The average score of an IQ test, administered to a large sampling of the general population, has been consistently around 100.

Answer:- The human brain can be studied meaningfully, but many researchers prefer to use simpler animal models because they allow more elegant investigation of neural principles that apply to all species. The see slug, for instance, is often used to study the neural mechanisms of learning.

Answer:- The most important reason for using rats and mice in research is to model aspects of human physiology and function, most notably to advance our understanding of human diseases.

Answer:- The nervous system of nonhuman animals resembles that of humans in many ways.

Answer:- All human beings are 99.9 percent identical in their genetic makeup. Differences in the remaining 0.1 percent hold important clues about the causes of diseases.
