Which of the following are true about factors that contribute to the high speed at which water is transported up a plant against gravity? [ Select ] ["True", "False"] A. Due to the cohesive nature of water, water molecules create hydrogen bonds with each other, creating a "chain" of water molecules. [ Select ] ["True", "False"] B. The inside of the xylem tubes are coated with a waxy, hydrophobic cuticle that allows for water to not get stuck to the sides of the xylem, which would slow down the rate of water transport. [ Select ] ["True", "False"] C. The pressure gradient needed to pull water up the plant is caused by transport of water from the soil being sucked into the roots. [ Select ] ["True", "False"] D. The waxy hydrophobic cuticle surrounding the outer layer of the leaf ensures that most water will be lost only via stomatal openings. [ Select ] ["True", "False"] E. Water evaporation from stomata creates a positive pressure resulting in a water potential gradient that has a higher water potential at the leaves compared to at the roots.

In the other major city, which had the work-from-home group had higher average morale and the test statistic of t = -1.956, if the company uses significance level 0.01 to test the advocate's claim that work-from-home leads to higher morale, what is the conclusion? Reject the null hypothesis. There is a statistically significant increase in average morale in the work-from-home group compared to the office worker group. Reject the null hypothesis. There is no statistically significant increase in average morale in the work-from-home group compared to the office worker group. Do not reject the null hypothesis. There is a statistically significant increase in average morale in the work-from-home group compared to the office worker group. Do not reject the null hypothesis.

Consider the ac equivalent circuit provided. Assume $R_E = 3k\Omega$ and $R_C = 5k\Omega$, and the transistor parameters for both $Q_1$ and $Q_2$ are: \begin{itemize} \item $I_{CQ} = 0.5 mA$ \item $\beta = 80$ \item $V_A = 100 V$ \item $V_T = 25 mV$ \end{itemize} Determine: $g_m = \boxed{} mS$ $r_{\pi} = \boxed{} k\Omega$ $r_o = \boxed{} k\Omega$ $A_{v1} = V_1/V_i = \boxed{} V/V$ $A_{v2} = V_o/V_1 = \boxed{} V/V$ $A_v = V_o/V_i = \boxed{} V/V$
