Actinomyocin-d was found to be effective in preventing the growth of rapidly dividing tumor cells by blocking dna replication. scientists discovered actinomycin-d also caused side effects like hair loss and a decrease in the number of red blood cells. which statement best explains the reason that actinomycin-d caused the side effects? a. actinomyocin-d alters the environment so that hair and red blood cells are killed b. actinomyocin-d affects all cell division, so healthy cells are also unable to divide c. actinomyocin-d targets tumor cells, and the side effects are due to the release of chemicals from the tumor cells d. actinomyocin-d kills the cells that support the hair cells and red blood cells leading to the death of these cells
