Answer:
troposphere
he troposphere begins at the Earth's surface and extends up to the stratosphere. It contains roughly 80 percent of the mass of the entire atmosphere and is where most familiar weather patterns form.
I can't give an exact answer if you do not provide any unit of concentration. The most common unit of concentration is molarity, which is the number of moles of solute over the number of liters solution. Say for example, the concentration of the solution is 0.1 M. To find the equivalent mass percentage, the solution is as follows:
The molar mass of Sr(NO₃)₂ is <span>211.63 g/mol.
(0.1 mol </span>Sr(NO₃)₂/ L solution)(211.63 g/mol)(1 L solution/ 1 kg solution)(1 kg/1000 g solution) * 100 = <em>2.12% Sr(NO₃)₂ solution</em>
The answer is c) to repair and replace other cells.
Cell division is the replication of cells by dividing itself into two, it does not prevent replication. Cell division does not make glucose either and cell division does not make ATP.
