I believe your question is asking what keyboard layout is most commonly used. If that’s the case, then the answer would be the QWERTY keyboard layout.
Answer:
Basically, calcineurin is an enzyme which dephosphorylates the proteins and tacrolimus is working against the calcineurin and it inhibits the action of calcineurin or we can say that it inhibits the dephosphorylation of protein.
Now, calcineurin acts on NFAT because it is substrate for calcineurin enzyme but it does not act on CDK1 as it is not substrate for calcineurin.
That's why, tacrolimus is an inhibitor of enzyme calcineurin and it will prevent the dephosphorylation of NFAT protein but it cannot prevent the dephosphorylation of CDK1 because it is not substrate for calcineurin.
Answer:
Well, I think that maybe it can by rain. Hope this helps!
Your answer is A, (because indeed it is the basic unit of even LIFE), B, (because MOST cells are used for ANY part of the body functions, which makes it unique and some have special features for specific jobs in da body), and D, (because of all of the built in parts of the cell that makes it function, like its mitochondria, etc.).
I hope I helped! =D

P.S.,
If it's only ONCE answer choice, your answer would be A., because that is a fact STRAIGHT from Science. ;-)
