Write a method replacekey in the minheap class with the following signature: public void replacekey(integer oldkey, integer newkey) the method will replace the first occurrence of oldkey with the newkey, and restore the min-heap property after the change. if the oldkey does not exist in the heap, the method prints an appropriate message and returns without changing the heap. example: suppose our binary heap object (bh) has the following keys: *** 4 6 7 32 19 64 26 99 42 54 28 then the method call: bh.replacekey (oldkey integer(54), newkey integer(2))

Use a software program or a graphing utility with matrix capabilities to solve the system of linear equations using an inverse matrix. x1 + 2x2 − x3 + 3x4 − x5 = 6 x1 − 3x2 + x3 + 2x4 − x5 = −6 2x1 + x2 + x3 − 3x4 + x5 = 3 x1 − x2 + 2x3 + x4 − x5 = −3 2x1 + x2 − x3 + 2x4 + x5 = 5

4. does the kernel phenotype distribution support the idea that the cob is the result of a dihybrid cross? what information supports your answer? if a dihybrid cross (i.e. f1 to f2 of standard mendelian crosses) is not indicated what conditions might contribute to this finding.
