The biochemical analysis of different chlorophyll pigments in plants would be most useful in determining:
A. how plants reproduce asexually.
B. the age of a plant.
C. which plants might have a common ancestor.
D. how plants pass favorable traits to their offspring.
E. why some plants produce hemoglobin.
Comparative biochemistry is the field of biology that deals with comparing similarities among different species DNA and proteins produced from the DNA. The more similar two different species DNA is, the closer the evolutionary link, and the more recent the two species shared a common ancestor.
