How do multicellular organisms begin?
multicellular organisms begin as a single cell.
Why there are no human fossils in coal?
Coal fossils formation begin about 60 million to 290 million years ago (before human existence) therefore no human fossils are found in coal.
All living organisms begin the breakdown of their food by?
Glycolysis
How are cells in multi-celled organism similar and different in cell in a single cell organism?
Both!All cells in a multicellular organism are identical genetically. This is because they are all formed from a single original cell (in humans, for example, the zygote) by mitosis.However, as the organism develops, some cells will become different in shape and function; this is called differentiation, and it allows different cells to specialize for different roles. Some examples in humans: nerve cells, muscle cells, white blood cells (and there is more than one kind of each of these).

How do multicellular organisms begin?
multicellular organisms begin as a single cell.
Do plants and animals begin their lives as multicellular organisms?
yes
Do all organisms begin as a single cell-?
Yes, all organisms begin as a single-celled zygote. Then they undergo meiosis and mitosis to replicate if they are multicellular or stay the same if they are single celled organisms.
How do all multicellular organisms begin?
By cellular reproduction. Cells reproduce asexually so if there is only one cell and it reproduces then there will be two cells and thus multicellular.
Which Unicellular or multicellular organisms in fresh or salt water begin with A?
It may be Algae or Alga, the singular of Algae.
Are ciliates unicellular or multi cellular?
Protists include unicellular, colonial and multicellular organisms Most protists are unicellular although (only one group) can be multicellular. There are types of algae, green algae known as Ulva, that are multicellular protists. They begin as colonies of unicellular protists known as Volvax, but the ones that break away are the multicellular version. The multicellular protists are without any specialized tissues. Protists used to be considered soley unicellular. Now that the molecular information has been redifined, protists are both unicellular and multicellular. .
What are some dinosaurs that begin with the letter U?
Ultrasauros dinosaur fossils date from the late Jurassic period. Utahraptor dinosaur lived during the early Cretaceous period.
When did large numbers of fossils first appear in the geologic record?
Large numbers of fossils begin to appear around 530 million years ago. It is called the Cambrian Explosion, because it occurred in the Cambrian period. The Cambrian period was the first part of the Paleozoic era.
What types of organisms have specialized cells?
mutlicellular
Did birds first begin to fly in the pre-Cambrian period?
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
What are some examples for index fossils that begin with the letter T?
trilobites
