Systematists have used a wide variety of traits to reconstruct the phylogenies of particular groups of organisms. which one of the following traits produces a good estimate of phylogeny?
- molecular traits
- gross morphological traits
- behavioral traits
- biochemical traits
- all of the above traits combined

All of the above traits combined.

Explanation:

Systematists may be defined as the field of biology that helps in the study of the diversification of the living organisms. The evolutionary relationship is studied in the form of evolutionary tree.

The different traits are used to study the phylogenetic relationship of the organisms. The organisms can be classified on the basis of the similarities and differences on the morphological traits, biochemical traits, molecular traits and behavioral traits.

Thus, the correct answer is option (5).

oceans

indian ocean

pacific ocean

atlantic ocean

arctic ocean

southern ocean

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
