a) The biological half-life is the time duration in which an organism takes to lose one half the amount of a content on a biological basis.

If a stable chemical compound is given to an individual and half of it is eliminated by the body within 'n' hours, the biological half-life would be 'n' hours.

b) Biological half life, tb = 64 days
nuclear half life, tn = 8 days

effective half life,
te = tb*tn/(tb+tn)
= ...

  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
