Two intracellular molecules, x and y, are both normally synthesized at a constant rate of 1000 molecules per second per cell. molecule x is broken down slowly – each molecule of x survives on average for 100 seconds. molecule y is broken down 10 times faster – each molecule of y survives on average for 10 seconds. a) calculate how many molecules of x and y the cell contains at any time? and what if the rates of synthesis of both x and y are suddenly increased tenfold to 10,000 molecules per second per cell in response to a signaling cascade, without any changes in respective degradation rates, how many molecules of x and y will there be after one second?

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
