How can you use classification to tell how closely organisms are related?
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
What is the most useful fact in determining whether two organisms are related?
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
Which two organisms in the chart are closely related?
Family and kingdom
Which two organisms on the phylogenetic tree are most closely related?
Clasifiaction
What two fields of study provide the core information that is used to classify organisms?
The two fields of study that provide core information for classifying organisms are taxonomy, which involves organizing and naming species, and systematics, which focuses on the evolutionary relationships among organisms. Together, these fields help scientists understand the diversity of living organisms and how they are related to each other.

What part of the scientific name will two organisms share if they are related?
When using genus and species in taxonomy , the genus will be the same for two very closely related organisms. The species will separate them.
What is the most useful fact in determining whether two organisms are related?
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
True or False If two modern organisms are distantly related in an evolutionary sense then one should expect that they should share fewer homologous structures than two more closely related organisms?
True. The more distantly related two organisms are in evolutionary terms, the fewer homologous structures they are likely to share. Homologous structures are features that have a common evolutionary origin, so closely related organisms are expected to have more similarities in their structures compared to more distantly related organisms.
Which two organisms in the chart are closely related?
Family and kingdom

Clasifiaction
The more classification levels that two organisms share?
The more classification levels two organisms share, the more closely related they are in terms of evolutionary history. Organisms that share many classification levels are likely to be more similar in terms of genetics, anatomy, and behavior.
Scientists know that organisms that are more closely related will have DNA sequences more similar to each other than organisms that are distantly related Which two organisms below would most likely h?

What are the two ways that energy stored in dead organisms is used?
Energy stored from dead organisms can be used in two ways. They can either be eaten by other organisms or decomposed by bacteria with the nutrients absorbed in the soil to be used by plants.
The greater the number of taxa two organisms have in common the more closely related they are?
true
