There is a widely accepted theory that the act of observation will change what is being observed.
Researchers usually want to observe an animal's natural behaviour - but this would be impossible if the animal knew the researcher was there because it would act differently with a human there.
Animal experiments are widely used to develop new medicines and to test the safety of other products.
Many of these experiments cause pain to the animals involved or reduce their quality of life in other ways.
If it is morally wrong to cause animals to suffer then experimenting on animals produces serious moral problems.
Animal experimenters are very aware of this ethical problem and acknowledge that experiments should be made as humane as possible.
They also agree that it's wrong to use animals if alternative testing methods would produce equally valid results.
Ecologists study relationships in the natural world. The study the connection between animals, plants and their environment. They usually teach or run studies as well.
they usually use a key which is a special chart for identifying and classifying features of animals and comparing it to those of a key.
How do scientists usually communicate and defend the results of an investigation
A geoscientist studies (usually only one of) the sciences related to the planet Earth, including geology, geophysics, hydrology, meteorology, physical geography, oceanography, and soil science.There are many well-paid jobs using geoscience and many more will be needed in the future. US Studies are predicting a shortfall of 135,000 scientists by 2024.
in the atmosphere
Because , animal field studies help the scientists provide data , and work with the hypothesis
They are trying to accomplish studying the animals in their natural habitat, behaving in natural ways, rather than scared of us.
because if animals were aware of humans they would be scared and act differently
to learn how animals in the wild interact with others in their groups, researchers carry out field studies
Usually a nuclear physicist.
Ecologists study relationships in the natural world. The study the connection between animals, plants and their environment. They usually teach or run studies as well.
Scientists first find out why the animal is getting endangered. Then, they usually start a campaign, such as "Help Save The (animal)!" The scientists can work with authorities to ban poaching from the area that the endangered animal lives in, or they can take in some of the animals and breed them. Scientists also tell pro. breeders about what they want.
A volcanologist studies the activity of volcanoes and their eruptions. These scientists are usually geologists who specialize in volcanology, and have at least a Master's degree in the discipline.
Not usually ... because even within a single species both size and color vary too much.
Taxonomists usually use a set of criteria that have to do with reproduction. So even if two species can reproduce an offspring, taxonomists usually make the distinction that the offspring must be able to reproduce as well. If this is the case, then they are likely to consider the two organisms as one species.
they usually use a key which is a special chart for identifying and classifying features of animals and comparing it to those of a key.
Only high level scientists can mutate animals, but usually they are only cloned, not mutated like they have special super powers.
