There is no simple answer to this question, what happens to an animal after the experiments depends on what was done to them. A number of the animals will go onto be used in other experiments and even a few of them may end up in a loving home. Occasionally cats and dogs from testing are adopted out to families and some of the primates used end up on wildlife reserves or in zoos, however this is not typically the case and usually only happens to animals that were used in behavioral as opposed to medical studies. Some experiments require the animal to be euthanized for sample collection or post-mortem examination. Even when the animal is not required the be euthanized side affects of the experiments have made the animal unsuitable for either further experimentation or life as a household pet.
Billions.
13, 000 animals died due to animal testing in 2009. A majority of these deaths were due to cross breeding, as scientists try to create more animal species.(cross breeding is when scientists combine two genes from two different animals.)
No they shouldn't, because were not the only ones with rights, animals have them to. If a cream got tested a little animal and died from it would be unfair because we have enough cream and that kind of stuff. :)
Koch tested his hypothesis by isolating bacteria from the blood of animals that died from anthrax, then injecting the bacteria into healthy animals to see if they developed anthrax. He also purified the bacteria and showed that it caused anthrax when injected into animals, fulfilling Koch's postulates to demonstrate that the bacteria was the cause of anthrax.
In an experiment, there are many variables (things that can't be controlled). For an accurate result, experiments must be done many times over to so that a pattern can be seen, giving scientists an idea of what the result is. For example, if you tested how music affected plant growth, and tested it once, if the plant died because of other causes, it could seem like the music affected the plant. By doing the experiment many times and seeing no affect on the majority of the plants, the scientists would see that music has no affect on plant growth. Scientists redoing experiments is to ensure that the results are credible.
The percentage of soldiers tat died of the war at Valley Forge was 80%.
No animals died on Noah's Ark.
Fossils are used by scientists to answer questions about species and maybe even dinosaurs. They use the fossils and run tests by using there DNA and seeing their molecular structure and running it by other animals for similarity's.
The saber-toothed cat or saber-toothed tiger or smilodon has been extinct for over 7 million years. Scientists think they died out because their food sources died. They had evolved to hunt big animals and could not deal with smaller prey.
