What advantage method of organism classification is that relationships between organisms can be proven even if structural analysis is misleading or inconclusive?
DNA sequencing
What relationships exists among organisms?
the answer is parasitism,competition,predation,symobis,
What is the chemical link between generations and all living organisms?
DNA is the chemical link between generations and all living organisms. DNA, which stands for deoxyribonucleic acid, is a molecule.
What is used to compare the antomy of organisms to show a possible ansestor?
Cladistics is the branch of science that traces bio ancestry. DNA is nowadays a powerful tool in use, and has overturned many traditional relationships based on form.
What evidence can be used to show that organisms share a common ancestor?
The DNA genetic code provides the best evidence of the common ancestry of life. Science has shown that there are many similarities between DNA sequences.
What is used as evidence for the idea of a domain Eukarya evolved from unicellular organisms?
Mitochondria and chloroplasts have their own dna
What organic molecule determines differences between living organisms?
dna
What kind of evidence is used by modern taxonomists to classify organisms based on how their relationships changed over time?
Modern taxonomists use molecular evidence, such as DNA sequences, to classify organisms based on how their relationships changed over time. By analyzing similarities and differences in genetic material, taxonomists can determine the evolutionary relationships between different species and create more accurate classifications. This molecular evidence complements traditional morphological and ecological data to provide a more comprehensive understanding of evolutionary relationships among organisms.
The DNA of all living organisms is composed of the same nucleotides It is only the sequence of nucleotides and quantity of DNA an organism possesses that cause the differences between organisms?
True
Why do DNA comparisons provide the most direct evidence of evolutionary relationships?
IT is believed that everyone has the same ancestor
How DNA evidence might be used to confirm scientists conclusions about any relationships between birds and seals?
DNA evidence might be used to confirm scientists' conclusions about any relationships between any animal and how closely related they are.
What similarities and differences could you look at when you classify organisms?
Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities
