Question 1
Provide concise explanations of each of the terms listed below. Please pay careful
attention to the mark allocations.
1.1.Donnan equilibrium
1.2.Edmund Newton Harvey equation
1.3.Countercurrent flow
1.4.Chlorocruorin
1.5.The bends / diver’s disease
Question 2
2.1 Calculate the quantity of oxygen in a bucket of freshwater (volume of 50 l) at
two different altitudes: sea level and 5,000 m.a.s.l. Use Henry’s Law for this
calculation and assume a temperature of 15°C. Show all your calculations
2.2 How long will it take a rainbow trout (Oncorhynchus mykiss) of 200g to
consume all the oxygen in the bucket for each of the scenarios, if it consumes oxygen
at a rate of 150 ml/kg of fish per hour? Assume the amount of oxygen is not
replenished during the experiment.
Question 3
Provide a brief overview in your own words of different approaches to measure
metabolic rate.
Question 4
Use a diagram to illustrate the effect of temperature on the oxygen dissociation
curve of a vertebrate. Explain briefly in your own words and discuss the
implications.
