Find the general solution of this ODE: $\frac{d^2y}{dt^2} + 11\frac{dy}{dt} + 18y = 2t^2 - 6 + 8e^{-4t}$ The solution will be of the form: $y(t) = Cy_1(t) + Dy_2(t) + y_p(t)$ so use $C$ and $D$ as the arbitrary constants. $y(t) =$

For a population at Hardy–Weinberg equilibrium in regard to a two-allelic gene (e.g. gene A with two alleles A+ and A–, the frequency of A–A– homozygotes will be the greatest when ____. Group of answer choices A+ > A– A+ < A– A+ = A– A+ >> A– A+ << A– The allelic frequencies and the genotypic distribution of these alleles will remain constant. The allelic frequencies will not change over time, but the genotypic distribution of these alleles will change (e.g. more heterozygotes, fewer homozygotes, etc). The allelic frequencies and the genotypic distribution of these alleles will change over time (e.g. more heterozygotes, fewer homozygotes, etc).

1) Given that $ \vec{E}=-\vec{\nabla} \phi-\frac{\partial \vec{A}}{\partial t} $ and $ \overrightarrow{E^{\prime}}=-\vec{\nabla} \phi^{\prime}-\frac{\partial \overrightarrow{A^{\prime}}}{\partial t} $, with 1 po $ \overrightarrow{A^{\prime}}=\vec{A}-\vec{\nabla} \lambda $ and $ \phi^{\prime}=\phi-\frac{\partial \lambda}{\partial t} $, then which of the following is/are correct? (Here $ \lambda $ is a scalar function) \[ \begin{array}{l} \xrightarrow[E^{\prime}]{\stackrel{\ominus}{P}}=\vec{E} \\ \text { - } \\ \overrightarrow{E^{\prime}}=\vec{E}+\vec{\nabla} \lambda+\vec{\nabla} \frac{\partial \lambda}{\partial t} \\ \stackrel{\text { - }}{\rightarrow} \\ \overrightarrow{E^{\prime}}=\vec{E}+2 \vec{\nabla} \lambda \\ \text { O } \\ \overrightarrow{E^{\prime}}=\vec{E}+2 \vec{\nabla} \frac{\partial \lambda}{\partial t} \end{array} \]
