There are nine major phyla described - Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, which of these do you consider to be the most successful? Explain your rationale for measuring success (e.g. total numbers, numbers of different species within the phylum, adaptability, specificity etc) and choose a representative animal within that phylum and discuss which aspects of its physiology and lifestyle have contributed to its success.

Which explanations accurately describe how cell structures interact in order to maintain homeostasis? Select all that apply.

The red fire ant is indigenous to South America. In recent years, this invasive species has become a pest for both humans and other ants in the southeastern United States due to their resource consumption and crop destruction.
What would be the safest way to reduce the impact of the non-native red fire ant while minimizing the impact on other organisms?

A damped mass-spring oscillator is subjected to a forcing F=F_0 cos⁡〖(ω_d t)〗. The steady-state solution is given by
x=A cos⁡〖(ω_d t-δ)〗,
where
A=A(ω_d )=(F_0/m)/√((ω_0^2-ω_d^2 )^2+(γω_d )^2 )
and
tan⁡δ=(γω_d)/(ω_0^2-ω_d^2 ).
The symbols have the usual meanings.
A sketch of the variation of amplitude versus driving frequency is shown in Figure 1:

Figure 1: Variation of amplitude with driving frequency
Explain why the amplitude is F_0/k when the driving frequency is zero and the type of forcing the system is subjected to.
Show that the frequency at which the amplitude attains a maximum is given by
ω_m=√(ω_0^2-γ^2/2)
and that the maximum amplitude is given by
A=A_0 Q/[1-1/(4Q^2 )]^(1/2)
where Q is the quality factor and A_0=F_0/k
