No. They use the structural characteristics of the organism physically and genetically.
appearance
its use to identify unknown organisms
you dont. sciensists never use age to classify a star
Biologists use classification to organize living things into groups so that the organisms are easier to study. :) Hope this helps
Scientists classify organisms by the dichotomous key. They classify by looking at if it moves or not, then they look at characteristics, then they can see what they are.
taxonomy.
Marine biologists use science just like every biologist. They study living organisms and how they interact with their environment. The only difference is that the marine biologist studies organisms in the water.
scientists use taxonomy to classify and separate them into different groups
They are classified according to the DNA they share with other organisms.
Taxonomists use fossil records, morphological structures, and DNA/genetic information in order to classify organisms into different kingdoms, phylums, and classes.
not physical apperance it is thier genes that you should use to classify
DNA is the answer.
