Final answer:
The correct representation of sigmoidal growth is Option E) W1 = Wmax / (1 + e^(-k(t - tm))).
Step-by-step explanation:
The correct representation of sigmoidal growth is Option E) W1 = Wmax / (1 + e^(-k(t - tm))).
This equation represents the logistic growth model, which is characterized by an initial exponential phase followed by a slowing of growth as the population approaches a maximum carrying capacity.
In the equation, W1 represents the final size of the population, Wmax represents the maximum carrying capacity, k represents the growth rate, t represents time, and tm represents the inflection point where growth rate is highest.
