Genes that code for a specific protein can be inserted into bacterial plasmids, and then the plasmids are used to transform cells. Many useful human proteins are now synthesized by these transgenic bacteria. Uses for the
synthesized proteins include human insulin used to treat diabetes and human growth hormone used to treat
dwarfism.
Which tenet of cell theory BEST serves as a basis for this type of biotechnology?
A)
All living things are made up of cells.
B)
All cells come from pre-existing cells by division.
C)
The cell is the structural and functional unit of all living things.
D)
Cells contains hereditary information which is passed from cell to cell
during cell division.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole

i think tornado but not 100%
