Neco 2022 Biology Question 10
Practice objective / multiple choice question 10 from the 2022 Neco Biology examination.
In an experiment, the plasma concentration of hormone X after a single intravenous injection follows first‑order decay described by \(C(t)=C_{0}e^{-kt}+C_{b}\), where \(C_{b}=5\) ng mL^{-1} is a constant basal level. The observed concentration is 85 ng mL^{-1} immediately after injection (t=0) and 25 ng mL^{-1} after 2 h. Determine the half‑life of the decaying component of hormone X in minutes.
