Click For Summary

The molar conversion for NAD+ at a concentration of 50 micromolar is calculated using its molecular weight of 660 grams/mole. This results in a concentration of 0.033 grams per liter. Converting this to nanograms per liter yields 33,000,000 ng/L. Further conversion to nanograms per milliliter results in 33,000 ng/ml. The calculations appear to be correct based on the provided values.

Homework Statement: Convert 50 micromolar NAD+ to ng/ml

Relevant Equations: I mole NAD+ = 660 grams
1 micromolar = 1 micromole/L
1,000,000,000 nanograms/gm

660 grams/mole for NAD+
50 micromolar is 0.00005 mole/L
0.00005 mole/L x 660 gm/mole = 0.033 gm/L
1,000,000,000 ng/gm x 0.033 gm/L = 33,000,000 ng/L
33,000,000 ng/L x 1L/1000ml = 33,000 ng/ml Is this correct?

looks OK to me

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
