Answer:
Skin cells are the epidermal cells which all of the organs In the body by forming a tissue called skin
Explanation:
Muscle cells have many mitochondria which provide a lot of energy during contraction and relaxation of the cells.
In 15 minutes 3 cells will be reproduced and in 30 minutes 6 cells will be reproduced
D(Cr) = 8,96 g/cm3
<span>M(Cr) = 63,546 g/mol </span>
<span>In a cell face centred cubic, there are 4 atoms of Cur . . . ! </span>
<span>n(Cr in 1 cm3) = m(Cu) / M(Cr) </span>
<span>n(Cr in 1 cm3) = 8,96 / 63,546 </span>
<span>n(Cr in 1 cm3) = 0,141 mol of Cr </span>
<span>Avogadro's number is : NA = 6,02•10^23 mol^-1 </span>
<span>N(Cr) = n(Cu) x NA </span>
<span>N(Cr) = 0,141 x 6,02•10^23 </span>
<span>N(Cr) = 8,488•10^22 atoms of Cr </span>
<span>N(cell) = N(Cu) / 4 </span>
<span>N(cell) = 8,488•10^22 / 4 </span>
<span>N(cell) = 2,122•10^22 cells in 1 cm3</span>
