Question 36 (1 point) Which of the following is a likely explanation for why tropical regions tend to have higher species richness compared to temperate regions? Tropical regions experience higher evolutionary rates due to warmer temperatures and faster physiological processes Tropical regions have fewer primary producers, leading to reduced competition among species Tropical regions are less stable over time, resulting in frequent species extinction Tropical regions have shorter day lengths, allowing for more concentrated ecological activity

1. Describe recursive algorithms for the following generalizations of SUBSET- SUM: (a) Given an array X[1.. n] of positive integers and an integer T, compute the number of subsets of X whose elements sum to T. (b) Given two arrays X[1..n] and W[1..n] of positive integers and an integer T, where each W[i] denotes the weight of the corresponding element X[i], compute the maximum weight subset of X whose elements sum to T. If no subset of X sums to T, your algorithm should return $-\infty$.

(ii) Let u(t), v(t) be a parametrization by t of a geodesic curve on the surface from a point P(x1, y1) at t = t1 to a point Q(x2, y2) at t = t2. Show that u(t), v(t) satisfy the equations (1+u'^2)u'' - 2u'v'v'' = 0 and (1+u'^2)v'' + 2u'u'v'' = 0, where u' = du/dt and v' = dv/dt. For the case when t = s, arc-length along the curve, show that these equations become d^2v/ds^2 + c^2v/(1+v^2) = 0, where c is a constant.
