∙ 15y agowell, if you are talking about the cellular level YES we may have cells that look similer microscopically but totally different function, an example would be the lymphocytes (the cells that fight microbes) has two types T and B, they have TOTALLY different functions but microsciplically you merely find the difference. about the organ level, i would say the digestive system, from the mouth to the anus they share the same basic structure but with simple modifications at each level , i.e. the stomach has a thicker muscular layer while the esophagus have a thick mucosa layer. i hope i helped well, if you are talking about the cellular level YES we may have cells that look similer microscopically but totally different function, an example would be the lymphocytes (the cells that fight microbes) has two types T and B, they have TOTALLY different functions but microsciplically you merely find the difference. about the organ level, i would say the digestive system, from the mouth to the anus they share the same basic structure but with simple modifications at each level , i.e. the stomach has a thicker muscular layer while the esophagus have a thick mucosa layer. i hope i helped

How does DNA sequence analysis contribute to evolutionary theory?
It's common sense that organisms with similar DNA are more related evolutionary-wise. Analyzing DNA can help us determine which organisms evolved from which organisms.
What is the grouping of organisms based on their common descent called?
The procedure of grouping organisms based on their evolutionary history is called evolutionary classification. It is also called Darwinian classification.
HOW ARE THE AREA OF STUDY -EVOLUTION AND CLASSIFICATION-INTERLINK?
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor. Thus, classification of species is in fact a reflection of their evolutionary relationship.
What information can be obtained from a cladogram?
Cladograms tell you which animals are the closet in relationship, which are the farthest, what characteristics the animals have in common, what characteristics they would need to have in order to be closely related to them, and the number of shared characteristics between the animals.
What is the function of organic molecules in unicellular organisms?
Organic molecules are the part of life we are living in earth... it is common for all level of organisms on earth.

What is an evolutionary?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
What is a group of similar cells that perform a common functions?
A group of similar cells that perfrom a common function form a tissue. A group of similar tissues that perform a common function form an organ, organs form organ systems, and organ systems form organisms.
What does the presence of Similar genes in very dissimilar organisms imply?
Common ancestor, or convergent evolution to the same function
What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
In evolutionary terms the more closely two organisms are the?
more recently they hared a common ancestor.
What is the grouping of organisms based on their common descent called?
The procedure of grouping organisms based on their evolutionary history is called evolutionary classification. It is also called Darwinian classification.
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Are similar genes evidence of common ancestory?
If organisms have similar genes, then they are closely related.
Phylogenetic trees are visual representations of .?
ancestral relationships of organisms Plato users c
Similar features in organisms that do not share a recent common ancestor are the result of what?
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
How are the areas of study-evolution and classification-interlinked?
Evolutionary relationships are traced in the classification of organisms. For classification of organisms, we look for similarities among organisms which allows us to group them. The more characteristics two species will have in common, the more closely they are related. It indicates that more closely two species are related, the more recently they would have had a common ancestor.
