It is not directly over a flame because it depends on the substance you might not want to heat it too much.you never know what could happen
Ions. Im 99.9% sure haha.
Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
Answer:
0.9%
Explanation:
At the instance where you add RBCs to a solution of 0.9% NaCl, they will maintain their shape as well as their size, this is simply to indicate an equilibrium. That entails that the solution is isotonic to the RBCs. This must mean that the concentration of solutes on each side must be equal otherwise osmotic pressure would force water either in or out of the membrane. Therefore, one can also safely assume that RBC's also have a solute concentration of 0.9%.
A for sure sparrows are like birds but sparrows build holes in trees and birds do nests in trees so for sure is a
