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.
Answer: By listening closely to the sound produced by rubbing of the components.
Explanation: Pericardial friction rub may have one, two, or three audible components. The rubbing of three components distinguishes a pericardial rub and it can be used to diagnose pericarditis. The pericardial friction rub can be heard even after breathe has been ceased.
Pleural friction rub has two components. Pleural friction rub can be heard only during inspiration. the Pleural friction rub causes pain on the lateral part of the chest wall. The intensity of pleural friction rub increases by pressing the diaphragm of the stethoscope over the affected area.
Answer:
electricity without added energy... i think, sorry if i'm wrong
Explanation:
The answer is D, because carbon footprint is defined by the amount of carbon dioxide released into the air by human activities.
