A certain signal molecule S in muscle tissue is degraded by two different biochemical pathways: when only Path 1 is active, the half-life of S is 20.s. When only Path 2 is active, the half-life of S is 101.s. Calculate the half-life of S when both pathways are active.

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
