AI Thread Summary
To prepare a 10^-5 molarity solution of phenylthiourea in a phosphate buffer, it is necessary to first dissolve the phenylthiourea in a minimal amount of ethanol. After dissolving, the solution should then be diluted to the desired final volume using the phosphate buffer. This method ensures that the phenylthiourea is properly solubilized before achieving the correct concentration in the buffer. The approach discussed is a common practice in solution preparation. Proper technique is essential for accurate results in chemistry experiments.

Homework Statement



I have to dissolve phenylthiourea in a phosphate buffer solution. The final molarity of the phenylthiourea is 10^-5, but it says to dissolve it in ethanol. Does this mean that I have to dissolve my weight of phenylthiourea in a minimal amount of ethanol, then bring that to volume with the phosphate buffer?

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...
