How do scientists determine the location and size of underwater mountain chains?
They determine it by using sonar.
Why do scientists keep track of populations?
By analyzing all this data, scientists can learn new ways to help control animal populations, determine what impact development might have on an animal population, and determine if there are enough individuals of a particular species in an area to allow for reproduction.
How can scientists determine whether or not they have created a new element or just an isotope of an element after smashing together particles in a particle accelerator?
essentially that's what a lot of elements are, but what makes an element a new element is if it can be reproduced and be stabilized for an amount of time
What determines the speed of a seismic wave?
By measuring the difference in arrival times at a seismometer station they can be used to determine the distance to the epicentre of an earthquake. They may also be used to estimate the properties of the subsurface and it's structure (refraction and reflection seismology). Please see the related questions for further information.
Explain how scientists use the law of crosscutting relationships to determine the relative ages of rock layers and a fault that cuts through the layers?
well love is a boy and a girl together ...........like meh3>
The apparent shift in the spectrum of a star as it moves toward or away from the earth is explained by the phenomenon known as the?
Doppler effect. This effect causes the wavelengths of light from a star to appear shorter (blueshifted) as it moves towards the Earth and longer (redshifted) as it moves away, providing valuable information about the star's motion in space.
An experimental design is usually looking to determine?
causation
What is percent error calculation used to determine?
It is used to determine how accurate an experimental value is.
Why is drawing conclusions difficult for scientists?
Many times, more than one theory can support a given set of experimental data. Therefore, it is difficult to determine which of the many available theories best fits the data presented.
How do scientists determine the sex of a fossil?
No
How do scientists use isotopes to determine the of an object?
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
How is the sex of an individual determined?
Scientists do not determine the sex of a fetus. Science does, but scientists do not.
How do scientists determine whether a hypothesis is correct?
Scientists determine whether a hypothesis is correct by performing experiments. They apply the hypothesized stimulus to one group of subjects and not to another group called the control group. If the experimental group is significantly different statistically from the control group the hypotheses is assumed correct. But, that isn't the end, if it's a significant finding other researchers try to duplicate the experiment. If they are unable to, it brings the hypothesis into question.
Scientists use a what to determine if a transformation was successful?
Scientists use a genetic marker to determine the success of a transformation. Genetic markers will change if the transformation has succeeded.
How do scientists determine the location and size of underwater mountain chains?
They determine it by using sonar.
Scientists can determine the age of some ancient artifacts usin what dating?
Scientists can determine the age of some ancient artifacts using Carbon-14 Dating.
How did the scientists determine the shape of the earth?
round shape
