All life on Earth have a common ancestor. But in order to produce the immense amount of difference among
all living organisms, certain ones had to evolve into distinct species.
All continents on Earth fit together like puzzle pieces in a giant landmass known as Pangaea that slowly drifted
apart.
An object in motion stays in motion unless acted upon by an outside force,
The universe began almost 14 billion years ago with a massive expansion event encompassing all the
universe's matter. That original movement continues today, as the universe keeps expanding outward.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
