Explain what happens during cytokinesis. This needs to be detailed.

During cytokinesis, which is a physical process of cell division, the cells divide the cytoplasm of a parent cell into two daughter cells. The ring on the outside of the cell which is also known as a contractile ring, shrinks at the equator of the cell which causes pinching, and the plasma membrane goes inward. After all that happens there’s something called a cleavage furrow which is the formation of a dip between the two cells while they are splitting.

(You can sum it up, but I hope this helps!)

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
