The blood cell will lose water and will undergo lysis.
Cell membrane is permeable to water and can get/lose water via osmosis. Osmosis is induced by the gradient of concentration of the solution. In this case, the 10M salt solution has a very high oncotic pressure that it will attract nearby water. That means the water inside the cells will be taken into the solution and cell will continue to shrink and then die.
It can become a sedimentary rock over time because of weathering. sedimentary rocks are rocks that have been broken down over time by water and erosion. hope this helps.
Because we have carbon in the ground in the air and every were else
