During а reseаrch expeditiоn in а newly discоvered cave ecоsystem, scientists collect two mysterious microbial samples: Specimen Alpha and Specimen Beta. In the lab, they make the following observations: Specimen Alpha is a single-celled organism. Its DNA is free-floating in the cytoplasm as a single circular chromosome. No membrane-bound organelles are observed, though ribosomes are present. Specimen Beta is also single-celled. Under the microscope, it clearly has a nucleus and other membrane-bound organelles. Its DNA is organized into multiple linear chromosomes inside the nucleus. Based on these observations, which of the following statements are correct? Select all that apply.
