Which of these is an advantage of a multicellular organism? a. one cell performs all the necessary functions b. their size allows them to retain structure easily c. they can reproduce quickly t d. they can perform more functions

I'd say the correct answer your looking for is B.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
