What modern cells do scientists believe to be close relatives of the Earth's first cells?
Scientists believe that modern cells called archaea are close relatives of Earth's first cells. Archaea are single-celled organisms that share similarities with the ancient cells that existed billions of years ago. Their ability to thrive in extreme environments suggests they may have characteristics similar to those of early life forms on Earth.
What grew from the work of many scientists who studied cells?
The field of cell biology emerged from the work of many scientists who studied cells. Through their collective efforts, scientists were able to discover the structure and function of cells, leading to the development of the cell theory, which states that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
What invention made it possible for scientists to discover and learn about cells?
The microscope was the invention that made it possible for scientists to discover and learn about cells. Its ability to magnify small objects allowed scientists to observe cells for the first time, leading to the development of the cell theory in the 19th century.
Wher does the cell theory state that all cells come from?
i really don't know what cells come from but i it in science class and still don't get it
What method do scientists use to make identical offspring from adult cells?
Scientists use a process called somatic cell nuclear transfer (SCNT) to create identical offspring from adult cells. This involves transferring the nucleus of a somatic cell into an egg cell that has had its nucleus removed, resulting in a genetically identical embryo. This technique has been used in various scientific studies and in cloning animals.
How do scientists know that fish existed before amphibians?
Scientists know that fish existed before amphibians because fish were found in a lower layer of rock.
How do scientists know that the cro-magnons existed?
They found their skeletons.
How did you know pangea existed?
Yeah because scientists from all around the world had expreinced it
How did scientists know from observational evidence that living things are made of cells?
Everything that they studied that had cells was alive, everything without them was not.
What modern cells do scientists believe to be close relatives of the Earth's first cells?

Archaea are single-celled organisms that share similarities with the ancient cells that existed billions of years ago.

Do scientists think living could have existed on neptune?
no
How did scientists determine that the Earth's mantle existed?
Scientists used detectors which determined the mantle existed. As well, scientists must hypothesize and theorize what cannot be readily seen, and make determinations based on the evidence that does exist.
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
Why were cells and what's inside of them such a mystery to scientists?
cells are just small enough to where we can't see them with the naked eye. Therefore, until someone came up with a microscope strong enough to see what's inside of them they had no idea.After they saw the outline of the cell, they knew that they existed. They didn't, however, know what was inside. When Rober Hooke first saw cells, he saw dead cells- the cells of cork. Because they seemed empty, he named them cells, after the small rooms that monks would pray in.People want to know what they don't. Its called curiosity. Therefore, because people didn't know what was inside of cells, it was appealing to them to find out.
What evidence led scientists to believe that neptune existed?
food
Why could scientists not see cells before the microscope?
The cells are too small for scientists to see with the naked eye. For some perspective on how small cells are, the dot above the letter 'i' is about the size of fifty cells. Scientists could not see regular cells with the eye alone.
Where do scientists get cells from?
scientist get there cells from humans, plant and animals.
