How many times have multicellular organisms evolved from unicells?

none :) a bacteria is considered to be unicellular but there are many bacteria that live in clusters or are filamentous, in that case the intercellular interaction is more important and we can in a way see that as a multicellular organism. Theoretically a bacteria is unicellular , always !!

What organism kingdom is multicellula?
The multicelular organisms are found in all of life's kingdoms. Multicellular life has evolved independently dozens of times we belive, once for plants, once for animals, once for brown algae and perhaps several times for fungi, slime molds, and red algae. Multicellular bodies exists in both prokaryotes and eukaryotes, and first appeared several billion years ago in cyanobacteria. Thus the whole basis of your question is wrong, multicellularity is NOT a sound discrimination basis for classifying Earth's life forms.
What changes that occur during differentiation in a multicellular organism?
Differentiation occurs several times during the development of a multicellular organism. The organism changes from a simple zygote to a complex system of tissues and cell types.
Explain how protists differ from other organisms?
All protists are eukaryotic (have a nucleus), most live in water. They are the "ancestor organisms" because they were the first organisms ever to exist.Protists are simply organisms that don't fit into any of the other kingdoms.The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes. This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction. Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.
Why are the rainy seasons and times of drought in the temperate grasslands?
kinds of resident organisms
Is it possible that an organism can be a source of food several times to other organisms?
predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey the organism that is attacked or a predator-prey relationship.

How are unicellular organisms better than multicellular organisms?
a multicellular organism is more advanced because a unicellular organism meets up to all its basic needs in just one cell which in a multicellular orgaism it does the same thing but with trillions of cells. So which do you think is more advanced?? Multi-cellular so pretty much no Actually, since a multicellular organism needs everything to function perfectly to sustain life, it has an easier chance of dieing if one little thing were to go wrong whereas a unicellular organism can surive in almost any enviorment
Are arcella multicellular?
yes it is but it can also be single at times.......
Where do scientists believe plants evolved?
They believed plants evolved from prehistoric times.
Skarmory evolved into how many times?
Skarmory does not evolve.
What lived in the Triassic?
Early Dinosaurs that evolved from the Jurrasic times.

Has the instrument evolved from an earlier instrument?
Yes, the Shaun in Tudor Times.

How are single-celled organisim similar to multi-celled organisim?
you times the singled celled one by two to get the multicellular organisim
Is it possible that an organisms can be a source of food several times to other organisms?
Yes is possible to process of fermentation
