Stem cells from an embryo are used to produce two cultures. Culture P develops into muscle cells. Culture Q develops into nerve cells. No mutations occur.
Which statement explains the difference between the cultures?
Mitosis gives the two cultures different diploid chromosome numbers.
Mitosis removes the chromosomes not needed by each culture.
Differentiation gives each culture a different set of chromosomes.
Differentiation produces different specialised structures in the two cultures.
