Answer:
It is a replacement that has an important effect on protein function because Arg and Gln are residues with different chemical properties.
Explanation:
In this case, Arginine (Arg) is a basic and positively charged residue, while Glutamine (Gln) is an uncharged (neutral) amino acid. Non-conservative substitutions like that are generally expected to have deleterious effects and they are generally removed by natural selection. Moreover, Arg is also a target for phosphorylation, which is the most important posttranslational modification. Phosphorylation is known to be capable of causing the activation of different proteins, especially kinases, and, therefore, the mutation at Arg109 might also inactivate the active site of this protein.
If they keep killing sharks, then the shark population will become extinct, I'm not sure if anyone wants to put a stop to it at all. About 100 million sharks are killed by humans every year.
Milk contains binds to capsaicin which cleans the palette of this irritant.
Answer:
Yes.
Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
Answer;
-Change in a population through genetic variation over time.
Explanation;
-Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is the process of genetic change from one generation to the next and may be caused by several aspects including mutation, natural selection, genetic drift, thought and technology.
