Which of the following are true about quorum sensing? Select all that apply. Group of answer choices Bacteria release autoinducers, a chemical signal that communicates to other bacteria on a general channel or a specific channel. An active area of research is looking into interrupting quorum sensing for treating antibiotic resistant bacteria If quorum sensing is interrupted before bacteria sense their surrounding numbers, they will not switch to their collective behavior Collective bacteria behaviors include bioluminescence, biofilm formation, producing toxins that cause disease, and many other collective behaviors. Quorum sensing is only present in no-till, regeneratively farmed fields

Let R be the region bounded by $y = 3.5\sqrt{x}$, $x = 3.25$ and the x axis. R appears below. Find the volume of the solid S obtained by rotating R about the line $y = -2.5$. S appears below. Hint: dV has the shape of a washer. $\text{Volume} = \int_0^{3.25} f(x)dx$ where $f(x) = $ $\text{Then volume} = \int_0^{3.25} f(x)dx = $
