Answer:
This term was created by Charles Darwin based off his research on evolution
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
The characteristic that the nurse will describe is HIGHER PITCHED.
When it comes to heart beating in children and adults, one major difference between the two is that, the heart sound typically auscultated in children has higher pitch than that of the adults.
I think theres a few methods to do it, but this is probably the most efficient.
Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin
Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.
To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%
Therefore 1% = 12.5/8.5= 1.470588
Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml
Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
