To what kingdom did the first eukaryotes most likely belong?
The first eukaryotes are most likely to belong to the Protista kingdom. These are mostly multicellular organisms with the earlier ones including organisms like Kneallhazia solenopsae and many more.
When was the theory of evolution discovered?
The theory of evolution was proposed by Charles Darwin in his book "On the Origin of Species" published in 1859. However, the idea of evolution had been discussed by earlier naturalists and scientists before Darwin.
Which of the following provides evidence that led many scientists to accept Darwin's theory of natural selection instead of earlier theories?
The discovery of genetics and the mechanism of inheritance through Gregor Mendel's work provided evidence supporting Darwin's theory of natural selection. This, along with the fossil record showcasing transitional forms and the observation of adaptation in response to environmental pressures, led many scientists to accept Darwin's theory over earlier ideas like Lamarckism.
The three-domain system recognizes fundamental differences between two groups of?
The three-domain system recognizes fundamental differences between the Archaea, Bacteria, and Eukarya domains. These differences are based on genetic, biochemical, and structural characteristics that distinguish each domain from one another. This system has replaced earlier classification systems that grouped all organisms into either plants or animals.
Do All cells contain a cell membrane and cell wall?
No, all cells do not contain both a cell membrane and cell wall. Animal cells have a cell membrane but no cell wall, while plant cells have both a cell membrane and a cell wall. The cell membrane serves as a boundary between the cell and its environment, while the cell wall provides structural support and protection.
What could be the first organisms?
[1] There's no all-across-the-board agreement. Some scientists believe the first organisms to be amoebae and fungi, others bacteria. The former are called eukaryotes, because they have nuclei. The latter are called prokaryotes, because they have no nuclei. Those who believe the eukaryotes were first call chloroplasts and mitochondria among the first organisms. Those who believe the prokaryotes were first call the monera among the first organisms. [2] A common assumption has been equating earlier appearance with simplicity. It favors the prokaryotes, for their lack of the more complex nuclei. [3] But a growing argument has been equating earlier appearance with complexity, later appearance with streamlining into simplicity. It favors the eukaryotes, for their nuclei which the projaryotes supposedly jettisoned in their efforts to streamline. [4] Another assumption has been linking earlier appearance with areas of heat, deep within the oceans. It favors the prokaryotes, which handled high temperatures much better than the eurkaryotes. [5] The oldest known fossils date back 3.5 billion years. They're the stromatolites of Glacier National Park. And they contain cyanobacteria microbes. [6] Some scientists say that there's an even older first organism that was the ancestor common to both eurkaryotes and prokaryotes. But they disagree on whether that ancestor evolved first into the former and then the latter, or vice versa.
Why are prokaryotes older then eukaryotes?
Prokaryotes are considered older because they appeared in the fossil record earlier than eukaryotes. It is believed that the simpler structure of prokaryotic cells made them better suited for survival in the early Earth conditions. Eukaryotic cells with their complex internal structures evolved later.
What organism do scientists believe are plants' ancestors?
The dinosaur is thought to be the ancestor of all things today.
Scientists believe that the more distant galaxies formed?
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
How did scientist find out about earlier scientists?
cause there scintest
How was Zacharias and Hans Janssens work affected by earlier scientists?
by a frog
Why earlier scientists could not guess about the gravitational force?
The earlier scientists did not care about the gravitation. They took the phenomena happening around them as granted. They did not think logically about gravitation while newton observed it carefully and minutely
What is a root that means before or earlier?
"Pre-" I believe :)
How did the earlier scientists and their contributions directly affect the discoveries of later scientists?
Since glass was invented, the scientists were able to create the microscope. If this was never invented, the scientists would never have been able to discover cells.

What do scientists mean by new species?
a new sp means that sp. which has not been seen earlier by anyone(people or scientists)/has no record in anywhere.
What did scientists think the Arizona crater was made by?
A volcanic steam explosion was earlier believed to be the cause.
