This was an
ideal place to study the evolution of the finches because basically due to Daphne's climatic
conditions, they found a natural environment with an extreme
climate, oscillating between periods of severe drought and abundant rainfall,
as well as an uncontaminated environment that had never been visited by humans,
which provided a wide natural selection for research on finches.
Could you possibly tell me what exactly you need help with? As my computer already has viruses, I am surely not going to click on any of those. Sorry!
This can be explained by analyzing the two chemical equations
The equation for photosynthesis is:
6CO2+6H20--->C6H12O6+6O2
The equation for aerobic respiration is:
C6H12O6+6O2--->6CO2+6H2O
The oxygen that is produced by the photosynthesis is consumed by the organism that do aerobic respiration.
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.
