How do cells in a multicellular organism become specialized? a. genetic recombination determines which genes are located in each cell within a multicellular organism. b. each type of cell in a multicellular organism has slightly different dna, allowing the different types of cells to specialize. c. the genes necessary for different types of cells to function segregate into different cell types in a multicellular organism. d. gene expression is regulated so that different genes are turned off and on at specific times during development of a multicellular organism.

D. Gene expression is regulated so that different genes are turned off and on at specific times during development of a multicellular organism.

Explanation:

In biology, cell differentiation is the process by which living cells "specialize" to perform a given function.

This process results from the differential expression of genes and is an ontogenetic process that occurs in the development of multicellular beings. Cells proliferate, differentiate, migrate and interact with each other and with the extracellular matrix, forming different tissues and organs.

In other words, the process of specialization in the cells of multicellular organisms occurs when gene expression is regulated so that different genes are turned off and linked at specific times during the development of a multicellular organism.

the answer is c.) there is a warm front in region a and a stationary front in region b.

cell division is not regulated in tumor cells.
