Construct a turing machine (your answer must show all of the 5-tuples involved) that validates (accepts) all strings of 0s and 1s that consists of an odd number of 1s and an even number of 0s. your turing machine should leave the read/write head positioned above the leftmost non-blank character if the string is valid; otherwise, it should leave the read-write head positioned over the rightmost non-blank to the right of the string. verify by providing a step-by-step trace that your turing machine validates 1101101 and rejects 110010.

C) electrons encircling a nucleus with neutrons and protons

The answer is probably c. xylem

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

The answer is c. risk
