Create a function called either-zero? that takes two parameters and returns true if one of the parameters is zero or false if neither are zero > (either-zero? 1 0) #t > (either-zero? 1 1) #f Part B: Create a function called same-sign? it should take two parameters. It should return #t if both are positive or both are negative and false if they are not. > (same-sign? -1 1) #f > (same-sign? -1 -1) #t

Which of the following factors would your hypothetical supervisor look at when deciding whether to test a biological material sample for dna? the amount of other evidence you have implicating a suspect in a crime the annual budget for the crime lab both of the above none of the above; you would almost always order a test

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
