N2 is what type of chemical species?
A molecule
How does the structure of macromolecules such as proteins act as an index of relatedness between species?
Organic molecules that just so happen to weigh more than 100,000 daltons, are from that point on then referred to as macromolecules which is related between the species.
How does protein comparisons contribute to evolutionary theory?
Protein comparisons, ie. DNA comparisons contribute to evolutionary theory by separating organisms in the plant and animal kingdoms. They go so far as to even separate individuals from one another within the same species. AKA Genetic Code.
What organelles are used in investigating evolutionary relationships?
Mitochondria and ribosomes are the organelles useful in investigating potential evolutionary relationships. For example, mitochondria can be used to determine relatedness between individuals and species.
A model known as a what uses DNA comparisons to estimate the length of time that species have been evolving independently?
molecular clock
What determines the degree of relatedness between two different species?
The degree of relatedness between two different species can be determined by taxons and a classificaton system. The classification system is used to organize things into different categories based on their evolutionary relationships.
What determines the relatedness between two different species?
whatever the dicoythamus key says is the difference
What do biologists use to establish whether or not two organisms are of the same species?
Comparisons of appearance, comparisons of structure, and comparisons of DNA and proteins.
How are differences between DNA amino acid sequence used to show relatedness between species?
the acid burns the fats
In what two ways G C content data are taxonomically valuable?
It has been observed that there is a correlation between GC content and relatedness between species. This means there is a similarity in GC content in closely relates species. And since taxonomy is involved with classification of organisms, GC contect is an excellent indicator of relatedness. Using this technique, the classification process can be made more precise
N2 is what type of chemical species?
A molecule
In the biological species concept of Ernst Mayr what aspect of a population is critical to determining a species?
interbreeding capabilities
Uses DNA comparisons to estimate the length of time that to species have been evolving independently?
Molecular Clock
How does the structure of macromolecules such as proteins act as an index of relatedness between species?
Organic molecules that just so happen to weigh more than 100,000 daltons, are from that point on then referred to as macromolecules which is related between the species.
What role does molecular evidence play in determining how closely two species are related to each other?
the role in which molecular evidence play in determining how closely two species are related to each other is through the cladogram
What is an atom that has gained an electron nonpolar molecule or a polor molecule?
The actual answer should be an anion which are polar species.
How does protein comparisons contribute to evolutionary theory?
Protein comparisons, ie. DNA comparisons contribute to evolutionary theory by separating organisms in the plant and animal kingdoms. They go so far as to even separate individuals from one another within the same species. AKA Genetic Code.
