Answer:
3) Each sample has the same number of molecules
Explanation:
1 mol are 6,022x10²³ particles. Moles of a chemical substance represent the number of molecules that this chemical has.
Thus, one mol of oxygen are 6,022x10²³ molecules of oxygen and one mol of nitrogen are 6,022x10²³ molecules of nitrogen.
Right answer is:
3) Each sample has the same number of molecules.

Scientists would deal with the aspect of cloning a particular gene into a bacterium or making of hybridoma cells that will produce the particular required protein. Engineers will then design and develop a bioreactor which is a programmed instrument that avails the required substances to the cells/bacteria in specific amounts and at particular time periods to grow and reproduce the cells in large amounts.
