PLEASE HELP plz ignore the one I choose bc it’s probably wrong

Your option(the third) is correct since all the cells in an organism have the same genetic material

the first one is false because all cells contain the same dna

the second one is false because the dna stays the same

the fourth one is false because sea animals have different dna

i also need this answer for on a project, does anyone know the answer? ?

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.
