Summary Introduction
The biogeochemical cycle of iron is referred to as iron cycle. Iron present in wide range of oxidation states (-2 to +7). But, on earth, it is chiefly existing in its +2 or +3 redox state. Thus, iron cycle refers to cycling of iron between its +2 to +3 oxidation states. This mechanism can be abiotic or enabled by microbes. For example, the rusting of iron (Fe2+ is abiotically oxidized to Fe3+ by means of oxygen. Subsequently, the abiotic reduction of Fe3+ to Fe2+ by biological cycling of Fe2+ oxidizing microorganisms or by iron-sulfide minerals.

You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

- 3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.)
