Based on the tree below, which statement is correct? A phylogenetic tree of four species. The main branch divides into two branches 2 a and 2 b. Branch 2 a leads to salamander. Branch 2 b divides into two branches 3 a and 3 b. Branch 3 a leads to lizard. Branch 3 b divides into two branches that lead to goat and human. Lizards and goats form a sister group. Goats and humans are the only sister group shown in this tree. Salamanders are a sister group to the group containing lizards, goats, and humans. Salamanders are more closely related to lizards than to humans.

Temperature and Heat Flow Question 2 of 6 (1 point) | Question Attempt: 1 of Unlimited 1 2 X 4 5 X6 A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 8.60 kg of water at 32.1 $^\circ$C. During the reaction 50.3 kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J$\cdot$g$^{-1}\cdot$K$^{-1}$. Round your answer to 3 significant digits.

5. For the system below find $A^k$ using the inverse Z transform of $(zl-A)^{-1}z$. Find the zero-input $x_{zi}(k)$ from $A^k x(0)$. Write an expression for the full solution assuming the input is $(-1)^k$, for $k > 0$. For the full solution use the time domain formula (with the summation formula) and plug in the zero-input part and plug in all available values into the sum part and simplify as much as possible. $x(k+1) = A(k)x(k) + B(k)u(k)$ $A = \begin{bmatrix} 0 & 1 \ -1/6 & -5/6 \end{bmatrix}$, $u(k) = (-1)^k$ for $k >= 0$ ($u(k) = 0$ for $k < 0$), $x(0) = \begin{bmatrix} 1 \ 0 \end{bmatrix}$
