Why is the classification of protists based on DNA sequences useful? * a. Because only protists have DNA b. Because it has confirmed the traditional categories for protists c. Because it has revealed evolutionary relationships, even among organisms that look diffferent d. All of the above are correct This is a required question (2) Why is a species with small population more likely than one with a large population to undergo an extinction? * a. Because small population are exposed to greater environmental changes b. Because genetic diversity is likely to be lower in a small population c. Because the mutation rate is too low d.
