2 flaws of molecular clock model in determining relatedness between species?

It assumes that all changes in amino acid sequence are random and aren't affected by natural selection and this probably isn't true. Moreover, sequences of amino acids change at different rates in different organisms

Is SO a molecular or ionic solid?
Molecular. Covalently bonded between the species.
Is carboxylic acid the same as volatile fatty acids?
No: they are two different and separate molecular moieties - or species.
Is sodium a molecular element?
A molescular species is informed about the height and power of the radioactive waves which were inferenced by sodiums almighty power
What are molecular weight markers?
To identify the approximate size of a molecule when run on a gel, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. Simply: So we know how long the DNA molecules are.
What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
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 role does molecular evidence play in determining how closely two species are related two 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 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
How are differences between DNA amino acid sequence used to show relatedness between species?
the acid burns the fats
Is SO a molecular or ionic solid?
Molecular. Covalently bonded between the species.
Biologists use molecular clocks to try to measure?
Generally, a molecular clock is used to describe the rate of molecular change over time that tells you when two species, or taxa, have diverged.
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
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 is the molecular formula of the principal molecular or ionic species present in glucose?
It is a molecular species with the formula C6H12O6
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.
Which molecular analysis would be the most useful in deciding the exact classification of similar species?
DNA sequencing would be the most useful molecular analysis in deciding the exact classification of similar species. By comparing the nucleotide sequences of specific genes or regions of the genome, scientists can identify genetic differences that can help distinguish between species that are otherwise very similar morphologically or ecologically. DNA sequencing provides a high level of accuracy in determining species classification and can help resolve taxonomic confusion.
