Why did Bacillus subtilis survive longer than Escherichia coli when exposed to uV light?
O Because Bacillus subtilis is a spore-former and spores are resistant to uV light.
O Because Bacillus subtilis cells are larger than Escherichia coli cells so it takes longer to kill them.
O Because Bacillus subtilis has a thick cell wall that uV light cannot penetrate.
O Because Bacillus subtilis has a capsule that protects it from uV light.
