How did the Miller-Urey experiment impact the way scientists think about the origins of life?
The Miller-Urey experiment demonstrated that simple organic molecules, such as amino acids, could be produced under conditions similar to early Earth. This suggested that the building blocks of life could have arisen from non-living matter through natural processes. It sparked further research into the origins of life and contributed to the understanding of how life might have began on Earth.
How old do scientists think that earth is?
4.6 billion years
What do most scientists think the earth's inner core is madde of?
iron
Scientists think the first water vapor on Earth came from?
From the oceans
Do scientists think living could have existed on neptune?
no
How many species do scientists think exist on earth?
Scientists estimate that there are between 8.7 million to 9.9 million species on Earth, although the actual number could be much higher due to many species still being undiscovered and undescribed.
Why is keplar 22b important?
keplar 22b is a planet. it is very important as scientists think there could be life on the planet as it has an atmosphere so it could have similar conditions as we have on earth, so it could be possible there is life on that planet.
Scientists think that the tilt of Earth's axis was caused by what hitting the Earth?
Many, many planetesmals and possibly a few protoplanets.
Why do scientists think the first living cells to spear on earth were pobably anaerobic heterotrophs?
there was no oxygen in Earth's early atmosphere.
Why do scientists believe think dinosaurs no longer roam the earth?
Because they're using a definition of "dinosaur" that allows them to think that.
How does urey's and miller's experiment support the theory that scientists think that the first life forms probably arose from nonliving materials?
Scientists don't "think" that the first life forms arose from non-living materials. However, they do accept abiogenesis as the only testable theory on the origins of life, as we know it. The Miller-Urey experiment set out to prove that the chemical components of life can arise from natural processes. While it does not prove life can come from non-living matter, it does show that its' components can arise naturally.
The validity of a theory is never examined directly.?
It would help if you could say something about the context in which this question has arisen and also name one theory that you think it applies to.
