Answer:
42,5 mL
Explanation:
We need to use the serial dilution formula beacuse we start with a stock concentrate solution and we need to prepare a new less concentrated one.

<u>DF in the dilution factor, Vi is the initial volume and Vf is the final volume.</u>
The first step is to have the same measurment unit so we need to convert 345 µg to mg.
we know that 1 µg equals 0,001 g, hence:

now the final volume is 0,345 mg protein/ mL and the inital volume is 15mg protein/mL, both of them are in the same unit so we can use the formula


Now since the question said that we already have 1.0mL of the amylase stock solution we need to subtract that 1.0mL to the 43,5 mg protein/mL

So, we need 42,5 mL of diluting buffer if we want a final concentration of 345 µg protein/mL (0.345 mg protein/mL)
Answer - Yes! of course. For better outlook you want to be in a city like Miami, FL U.S or someone populated cause that is where your able to find patients in need of recover. Other then that we will always need occupational therapy assistant because its crucial to the recover with some help and maintenance.
Reasoning - It is in fact true because in a city you can find a populated are that probably fractured their hand and needs some assistant for help recovery if the main doctor is not there.
