What are three discoveries about cells did scientists make several hundred years ago?
Every organism is composed of cells. Every cell exist from pre existed cell. Cell is the basic thing of life
Which scientist worked in the field of pressure?
Oxygen was discovered for the first time by a SwedishChemist, Carl Wilhelm Scheele, in 1772.
What type of scientist studies biotic factors?
I would describe such a scientist as an environmental scientist.
Organisms are placed into a kingdom based on what four characteristics?
I think that the seperation of organisms in the kingdoms are sorted by there characteristics like how many cells it has or the ability to make their own food or what kind of cell type it is
Which experimental discovery led Niels Bohr to revise Rutherford's model of the atom?
Jj Thompson in 1904.................. Actually it was Ernest Rutherford who Disproved it in 1911. JJ thompson was the creator of the plum pudding theory
Why is gps navigation important earth scientist?
GPS which is the global positioning systems are important in agriculture because it helps farmers in ditecting the amount of nitrogen,phosphorus required in the soil.It is a quit expensive and advanced agricultural system and is mostly used by large scale famers.
They are also used by commercial ships, instead of using celestial navigation. You don't need a clear sky and the position is continuously updated. Bad weather systems can be more effectively avoided and the course re-routed. This saves time, money and damage.
People find them useful in cars, to tell them exactly where to go. Commercial traffic saves time and money. Private users have more peace of mind that they will not get lost.
Vehicles involved in accidents, can get emergency services to them more accurately, either by the services getting there more reliably, or by the victims knowing where they are in the first place. Saving time and lives.
Scientist who studies viruses?
Virology is the study of viruses and their evolution, structure, classification. It also is complexes of nuclies acids and proteins that help all living cells.
What is the name for the skills scientists use to solve problems?
If you mean the process by which they evaluate problems and go about solving them, they use what is called the "scientific method." This method involves a few steps:
1. Define the problem
2. Evaluate the problem and its parameters.
3. Create a hypothesis (or an educated guess of what method you think will solve your problem)
4. Conduct an experiment using your hypothesis. (Test your hypothesis)
5. Evaluate your results and collect data (did it work?)
6. Deduct a conclusion (if it worked, that's your answer, if not, figure out why it was not the solution to your problem and come up with other possibilities)
What organism do scientists believe are plants' ancestors?
The dinosaur is thought to be the ancestor of all things today.
In the University of Paris, France (the Sorbonne)
Marie Curie lived in a smart family, but were poor because of their belief in polish culture. So, Marie had to work as a governess before she went to university, to pay for herself and to help her sister out. When she got her degrees and doctorate in physics and chemistry, she worked in a lab finding out more about her discovery. When her husband was run over, she was given the position of first femal professor at Sorbonne University in Paris.
She worked in her lab, in her house, and at a school.
Why scientists collect information about what is already know when trying to solve a problem?
Scientists do this because very few people-even scientists-can think of completely new problems to solve. This means that it's extremely likely that a scientist will find that some other person will have published information that will be useful to know in their research.
Which supercomputer is developed by the Indian Scientists?
PARAM PADMA is the name of the first super computer.
Why do American scientist use Kilometers instead of miles?
Because scientists are educated people who understand that their results and reports may be published and read by people outside of America.
What seems strange is that some people still use Miles rather than Kilometres.
What are the names of Anton van Leeuwenhoek' siblings?
Philips Teunisz was his father and his mother was magriete jacobsdr van der berch.
How do the scientists study the universe?
I would like to add one more additional method for investigating universe, it just appeared in my brain.
well the method is being used in large hadron collider(which is a particle collider), in which smallest particle of any atom are collided at very high speed.
it tells us about the born of the universe, dat how did it happen.
They say "At Cern, the Large Hadron Collider could recreate conditions that last prevailed when the universe was less than a trillionth of a second old. It has massive particle detectors called the Compact Muon Solenoid."
Two ways technology helps scientist?
1 is that technology is something like a problem to slove but the only way to do that is in a scientific way.
2 is that when dealing with science u can explain in manny ways but the way u explaining its using technology.
3 any thing u do in science is technology......
How do scientists estimate the age of earth to be 4.6 billion years old?
The age of rocks is usually determined by radioactive (or radiometric) dating. Some elements are radioactive and gradually convert from one isotope to another. For example, uranium 238 (238U) will gradually convert to lead (206Pb). It will do this at a constant rate. The rate is described as a half-life of the isotope in question. This is the period of time it takes for half the atoms of 238U to convert to lead. For this particular element, the half-life is 4.47 billion years and uranium/lead dating is useful for rocks between 1 million and 4.5 billion years (as luck would have it!). Other elements are also used (potassium/argon for example). The choice of element depends on how widespread it is - if it isn't found in many rocks then it's not very useful. And how long the half-life is - if the half life is shorter than the age of most rocks then its equally unuseful. Radiometric dating can only be performed on igneous rocks. The uranium/lead elements are most often used because igneous rocks often contain uranium and the half life is so long. The oldest rock found is around 4.54 billion years old. This is consistent with the age of rocks from the moon and from meteorites, which all point to an age around 4.54-4.56 billion years. Separate studies of the sun's mass and luminosity suggest that the solar system itself can't be much older than these rocks. All of this is well-known scientific information. The arguments against it lack scientific credibility, and most of them are posted by so-called Young Earth Christians. The vast majority of the scientific community accepts as valid the information provided by radiometric dating. The claims made about "assumptions" in radiometric dating of billion-year old rock are actually stepping stones that those who work in the field have worked hard to eliminate as impediments to the accuracy of their measurements. Making a "claim" about any aspect of radiometric dating without scientific proof that something is wrong, as has been done, does not invalidate the work - or the mearurements. The earth is about four and a half billion years old.
What scientist proposed that DNA was a triple stranded helix?
Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .
What were Newton's contributions as a philosopher?
Newton used the ideas of Plato in his work by reading Plato's works and ideas. He then went and passed it off as his own work. Therefore, he basically added more of his own ideas to Plato's works.
im sorry i do not know the answer but if ur single im free
What does NOT support the continental drift theory?
they couldn't agree on how it separated or what made it separate.
What did spallanzi do to improve upon redi's and needham's work?
He boiled two containers of gravy, assuming that the boiling would kill any microorganisms that were present.
He boiled two containers of gravy, sealed the top of one and left the other open. After a few days had passed he saw the unsealed gravy was teeming with microorganisms, while the closed bottle was clean of microorganisms.
