Question
Chapter 31.4, Problem 3EQ
Summary Introduction
To determine: The way in which the measurements made by Browning and Gunning led them to their conclusions after adding an excess amount of unlabeled CO2.
Introduction: Specialized placental transfer tissue helps in transfer of nutrition from mother plant to the embryo plant. This function of placental transfer tissue was first discovered by Adrian Browning and Brian Gunning by an experiment.

Exercise 4.
(Rabbits vs. Foxes) The Lotka-Volterra predator
prey model is given by the system R = aR – bRF, F = -cF + dRF, with parameters
a, b, c, d > 0 and R(t) population of rabbits in time, and F(t) population of foxes in time.
a) Discuss the biological meaning of each term in the equations and comment on any
unrealistic assumptions.
b) show that the model can be rewritten (adimensionalization) as i= ¤(1 – y), ý =
py(I – 1).
c) Find a conserved quantity in terms of the dimansionless variables in (b).
d) Show that the model predicts cycles in the population of both species for almost all
initial conditions.
