What scientist discovered the seven colors of the rainbow?
Noah The Bible in Genesis says that Noah was the first person to see the Rainbow after the Flood. Some may think this crazy. But think of this. One theory is that the earth was covered with a thick misty haze and that you could not directly see the Sun. Then when the rains came that caused the Great Flood, the sky cleared up and produced the Rainbow. Some theories also say that the atmospheric pressure at the time of Noah was twice as much as it is today. These scientists say that is why they lived longer in those days.
What is a scientist that studies elements atoms and molecules called?
Chemist
A scientist that studies elements atoms and molecules is called a Chemist
Which of these scientists would be interested in the earth layers?
They want to look into further details about any natural disaster that might happen that can damage the earth or OR
they just want to discover more about the Earth's layers
If string theory is true, strings. If not sub-atomic particles
Why do scientists need to classify living organisms?
Most flora and fauna have several common names; names which can be different in other parts of a country. The scientific names are agreed and are specific. For instance, a common hedgerow weed is Jack-By-The-Hedge (Alliaria petiolata), which has several common names, but will always be scientifically known as Alliaria petiolata throughout the scientific world.
What was Isaac Newton's mother's full name?

How did john snow help save lives?
Snow used epidemiological and statistical methods to identify the water pump in a district of London that was the source of cholera germs that had caused an outbreak of the disease. In doing this he helped to lead the way in applying similar approaches, even before the germ theory of disease had been developed. Please see the link.
Whose work proved conclusively that spontaneous generation of life from non-life was not possible?
Louis Pasteur was the one who used a swan necked flask to show that when particles were not allowed to touch boiled broth, it would not turn cloudy, but that when it was open to air, cloudiness quickly appeared.
Are scientists most concerned about the gases that have increased by the greatest percentage?
Carbon dioxide (CO2). This is the one that is largely contributing to global warming, and it's the one that we can possibly do something about, by reducing our burning of fossil fuels and by stopping deforestation.
Other greenhouse gases are more powerful, like methane, but the amount so far is small compared with CO2.
What instruments scientists use to study the universe?
anything like
Seismometers- Are used by seismologyto measure and record the size and force of seismic-wave.
Tilt meter- is an instrument designed to measure very small changes from the horizontal level, either on the ground or in structures.
Richter scale- Measure of the magnitude of seismic waves from an earthquake.
Magnetometers- An instrument for measuring the magnitude and direction of a magnetic field
Anemometer- Is an instrument use to determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
What are the scientific attitudes that a scientist should possess?
A good scientist should possess the following qualities:
1. A scientist must be curious about the world Example: Galileo Galileo's curiosity about the heavenly bodies made him the first person to use a telescope to study the moon, the sun, the planets and the stars.
2. A scientist is logical and systematic Example: Among the reasons why Gregor Mendel discovered the principles of heredity when others have failed was his logical experimental methods and his careful and accurate record keeping.
3. A scientist is open-minded and free of bias Example: An open-minded person is one who can modify plans or discard hypotheses if necessary. One such person was Johannes Kepler who was hired to develop evidence that planets moved along perfect circles.
4. A scientist is intellectually honest Example: Isaac Newton built his laws of motion on the previous work of Galileo and others.
5. A scientist works hard and is persistent Example: Marie Curie was the first person ever to be awarded the Nobel Prize twice. It was not surprising considering how hard she worked.
6. A scientist does not jump to conclusions Example: John Dalton's atomic theory was backed by experimental evidence. He was not the first to propose that the atom was the smallest particle of matter, but he was the first to use experimental evidence to support his theory.
7. A scientist is a creative and critical thinkerExample: Albert Einstein was able to derive his theory of relativity because he went beyond what was given and known at that time. He saw links and connections where others did not. He looked at things from different perspectives.
8. A scientist is rational
9. A scientist is willing to suspend judgment until he is sure of his results
10. A scientist tries new approaches to arrive at solutions
In addition:
A scientist must have an open mind and be curious. It is fine to have an idea about how or why something is the way it is, but the scientist should then seek to prove or disprove this "hypothesis" and should then be willing to change their ideas depending on the results of their experiments, rather than to continue believing in their original idea even if the evidence of their experiments is sticking up against it. 1.Keen Observer 2.creative 3.patient 4.curious 5.humble 6.intellectually honest 7.objective 8.Aware of the limitations of Science 9.Persevering 10.Open minded
Socioeconmist.
What did isaac Newton define in his first book The Principia-?
In his first book, The Principia, Newton defined the three laws of motion that govern the planetary bodies. Isaac Newton was an English physicist.
The study of flora is essentially the study of plants. By definition this would be considered botany. Botany is a noun, meaning the study of plants.
Why is it important for scientists to find out more about cell division?
Cell division is essential to life - all forms of reproduction, as well as repair, rely on cell division. Learning about cell division gives a person an understanding of one of the most important processes in biology.
Could scientist experiment on humans?
It can go both ways. Many people have been helped due to advances in genetic knowledge, which has allowed us to further our treatment for many medical conditions.
Billions of people's lives have been saved or helped due to vaccinations, which have pretty much wiped out diseases like polio and mmr. Without advances in genetic knowledge, developing and improving these medicines would be impossible.
However, there are risks to genetic experimentation. Since it's not perfect, there are possible side-affects and things that could go wrong, which is why medicines are extensively tested before available to the public.
There is also controversy in stem cell research. Many believe that this is morally wrong for the baby, but so far scientists have found no major side-affects or harm to the baby from this type of research.
no
cause of death: heart failure
death date: May 27, 1910
What type of scientist studies moths?
A lepidopterist is a person who specializes in butterflies, moths, and skippers.
How do scientist conduct controlled experiments done in space?
Scientist use robots to search for available forms of life outside of earth. They also use them to explore space itself. Robots such as the mars rover are great examples of how robot are used to explore other plantes and possible life outside of earth in case something were to happen on earth. But its safe to say we're safe for now.
How do scientist construct models of the sun?
by comparing numerical mathematical models to lots and lots of observations.
Archimedes of Syracuse.
How do scientist think protobionts formed?
Biological molecules were trapped in molecular bubbles.
Cell like structures formed from molecular bubbles-apexx
Which Greek philosopher first proposed that matter was composed of invisible particles?
These philosophers were Leukippus and his disciple Democritus.
