What is a possible explanation for obtaining the same result of isolating a single colony containing two distinct species of bacteria after performing a quadrant streak twice?
a) The bacteria species are in a symbiotic relationship, allowing them to grow together.
b) The agar used in the experiment is contaminated with multiple bacterial species.
c) The bacteria species are closely related and have similar growth patterns.
d) The streaking technique used does not effectively separate bacterial species.
e) The colony contains a mixture of genetically identical bacteria that have undergone mutations.
