b. surface-to-volume ratio remains constant as cells increase in size
c. there is no relationship between surface-to-volume ratio and cell
d. small cells have a smaller surface-to-volume ratio than larger cells

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
