Which of the following is an example of deep homology? The eyes of humans and fruitflies are morphologically very different, however they use the same proteins to transduce light into a nerve signal. There is very little genetic diversity across the human population near our lactase gene. Many proteins found in venoms are also expressed in other tissues. Two different members of the same gene family have gained the ability to digest cellulose in different vertebrates

(1 point) If the series $y(x) = \sum_{n=0}^{\infty} c_n x^n$ is a solution of the differential equation $2y'' - 5xy = 0$, then $c_{n+2} = \frac{5}{2(n+2)(n+1)} c_n$, $n = 1, 2, \dots$ A general solution of the same equation can be written as $y(x) = c_0 y_1(x) + c_1 y_2(x)$, where $y_1(x) = \sum_{n=0}^{\infty} a_n x^{3n}$, $a_0 = 1$, $y_2(x) = \sum_{n=0}^{\infty} b_n x^{3n+1}$, $b_0 = 1$ Calculate $a_1 = $ $a_2 = $ $a_3 = $ $b_1 = $ $b_2 = $ $b_3 = $

Question 4 (6 marks) On 1 July 20x1, Large Mart purchases a new building (and the associated land) in Sydney. Large Mart paid $1,000,000 for the land and $800,000 for the building. Large Mart will use the building for 30 years, after which time the building will have a residual value of 50,000. Large Mart will depreciate this building, using the declining balance depreciation method, with a yearly depreciation percentage of 6.67%. On 1 July 20x3, Large Mart decides to revalue the building (current fair value 600,000) to its most up-to date fair value. Required: A) Calculate the yearly amount of depreciation for the building for the year ended 30 June 20x3, AND provide an outline of your calculations. (2 marks) B) Provide all journal entries that are necessary to record the depreciation of the building for the years ended 30 June 20x2 and 30 June 20x3, AND the revaluation of the building on 1 July 20x3, AND provide an outline of all necessary calculations.
