Rudolf Virchow apparently received no help in 1858 for his opinions on cell theory. Some of his opinions, however, were based upon research by Theodor Schwann.

Which theory is supported most by the finding that the moon is similar in composition to the outer portions of Earth?
The "giant impact" theory. The most popular current theory of the Moon's formation is that during the early times of our solar system very shortly after its formation, another planet perhaps as large as Mars collided with the proto-Earth. The cores of the two planets merged (resulting in the unusually massive iron core of the Earth) and the debris blasted into space by the collision partly fell back to Earth and partly formed the Moon.

What is the plate techtonic theory?
The plate tectonic theory states that new Earth crust is being formed while old crust descends back into the mantle. Uneven heating in the mantle causes convection which keeps the crust in motion. The constant movement of Earth's plates are the result of the three types of boundaries, divergent, convergent, and transform, and the convection in the mantle.
Which observation provides the best evidence that earth revloves around the sun?
The heliocentric model provides evidence that the earth moves around the sun. This theory was discovered back in ancient Egyptian times.
Could artificial snow be used to replinish our melting polar ice caps?
I had a similar idea with recycled plastic used to make large sheets to extend the polar ice caps back to what they were 30 years ago. I'm with you. Reflects the sun the same. Returns the climate to 30 years ago. Should even make it snow, in theory & bring back the natural snow where it should be. I think it is about the science of light reflection's effect on climate. Artificial polar ice caps.
Who discovered cancer cells?
Some descriptions of cancer go back to ancient Egypt as far back as 1600 BC and the understanding of cancer was significantly advanced during the Renaissance period. However, Sir Rudolf Virchow, a German biologist and politician, is generally credited with discovering the first cancer cells. As Giovanni Morgagni had linked autopsy findings seen with the unaided eye with the clinical course of illness, so Virchow correlated the microscopic pathology.
Who developed cell theory?
This happened in the 15th century known as 1600s Robert Hooke, Anton Van Leuwenhoek, and Theodor Schwann, and Matthias Schielden are discovery and observatory to this.The Cell Theory was first discovered in 1836.
Which experiments led to changes to the original cell theory?
Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory.

What is an explanation in science that has a lot of evidence to back it up?
I think it is theory
How is a hypotheseis different from a theory?
A theory has been proven and has lots of data to back it up while a hypothesis is simply an educated guess that has some data to back it up.
What is the different between postulate and theory?

What is the difference between equity theory and social exchange theory?

The definition of a theory is an untested hypothesis. An example of a theory: "By going backwards around the world in a spaceship, we may be able to go back in time." I thought of that myself, not to brag.
