How can the cells in a multi-cellular organism differ from each other when they all have identical DNA?

They differ based on what genes are turned on and off. Some gene portions, called introns, are essentially useless, and they are not coded by into RNA during transcription. Exons are the portions of DNA that are coded into a complementary RNA strand during transcription, and then are sent to ribosomes to be translated into various proteins that the body's cells use (and in doing so, determine the differences among certain cells in the body). This process is called cell differentiation, and it is what transforms stem cells of the spinal fluid into cardiac cell, neurons, even skin and liver cells, etc.

∙ 13y agodude are u from NVOT cause i have the same hw lololol
well i guessed that some cells have different purposes such as red blood cells ( carry oxygen)
white blood cells ( i think like protect from viruses) and etc.

How do bacteria differ from the cells of the organism they infect?
Bacteria are unicellular. The cells of the organism they infect are, quite often, part of a multicellular organism.
How does a cell develop into a multicellular organism?
as a multicellular organism develops, its cells as a multicellular organism develops, its cells
Do multicellular organisms differ from unicellur organisms?
A colonial organism is a collection of one-celled organisms living together. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony can, if separated, survive on their own, while cells from a multicellular life-form (e.g., cells from a brain) cannot. Multicellular organisms consist of differentiated cells that perform special tasks. The entire organism requires all the different types of cells to be present, and the individual cells can not survive without being in the organism
Are all cell the same in a multicellular organism?
Almost all cells in a multicellular organism are genetically the same - i.e. they have identical DNA. However, through a process called "differentiation", cells diverge in size, shape, and function by having different sets of genes turned off or on.
