Why are molecular clocks not accurate when making comparisons between distantly related organisms?

Because rates of divergence are not static, but variable. The more distantly related the organisms, the longer the period of divergence. The longer the period of divergence, the more room there is for variability in the rate of divergence, the less accurate an estimate will be.

How does the phylogeny based on molecular analysis compare to the original phylogeny based on anatomical similarities?
Phylogeny based on molecular analysis can sometimes differ from the original phylogeny based on anatomical similarities because molecular analysis looks at genetic similarities, which may not always align with physical traits. Molecular analysis can provide a more accurate depiction of evolutionary relationships among organisms, as it is less affected by convergent evolution or other factors that can cloud anatomical comparisons.
Why do scientist today rely on molecular and genetic similarities to classify organisms?
Because it is more accurate than using physiological differences as used in the past.
How do you find molecular fomula?
The molecular formula is established only after an accurate chemical analysis of the compound.
What do modern scientists use in classifying organisms that Linnaeus did not use?
Modern scientists use genetic sequencing, molecular studies, and evolutionary relationships to classify organisms, techniques that Linnaeus did not have access to. These methods provide a more accurate and detailed understanding of the relationships between different species.
Do ionic compounds have molecular formula?
Sort of, though the term "chemical formula" is more accurate for describing compound molecular or otherwise.
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.
Is the simplistic formula in chemistry the molecular formula?
this formula tells the accurate ratio of a molecule or compound
What are two goals of the system to classify organisms?
I think its To show accurate relationships between types of organisms and to group them into Linnaean categories
What physician made accurate drawings of the organisms of the human body?
Andreas Vesalius

How did classification change?
Classification has evolved from traditional methods based on physical appearance and behavior to more advanced techniques using DNA analysis and molecular biology. This has allowed for more accurate categorization of organisms and has highlighted the evolutionary relationships between different species. The shift towards molecular classification has greatly improved our understanding of biodiversity and the interconnectedness of all living organisms.
