Need done for Date Structures please! 4.18 LAB: Sorted number list implementation with linked lists Step 1: Inspect the Node.h file Inspect the class declaration for a doubly-linked list node in Node.h. Access Node.h by clicking on the orange arrow next to main.cpp at the top of the coding window. The Node class has three member variables: a double data value, a pointer to the next node, and a pointer to the previous node. Each member variable is protected. So code outside of the class must use the provided getter and setter member functions to get or set a member variable. Node.h is read only, since no changes are required. Step 2: Implement the Insert() member function A class for a sorted, doubly-linked list is declared in SortedNumberList.h. Implement the SortedNumberList class's Insert() member function. The function must create a new node with the parameter value, then insert the node into the proper sorted position in the linked list. Ex: Suppose a SortedNumberList's current list is 23 47.25 86, then Insert(33.5) is called. A new node with data value 33.5 is created and inserted between 23 and 47.25, thus preserving the list's sorted order and yielding: 23 35.5 47.25 86 Step 3: Test in develop mode Code in main() takes a space-separated list of numbers and inserts each into a SortedNumberList. The list is displayed after each insertion. Ex: If input is then output is: Try various program inputs, ensuring that each outputs a sorted list. Step 4: Implement the Remove() member function Implement the SortedNumberList class's Remove() member function. The function takes a parameter for the number to be removed from the list. If the number does not exist in the list, the list is not changed and false is returned. Otherwise, the first instance of the number is removed from the list and true is returned. Uncomment the commented-out part in main() that reads a second input line and removes numbers from the list. Test in develop mode to ensure that insertion and removal both work properly, then submit code for grading. Ex: If input is then output is: main.cpp #include <iostream> #include <string> #include <vector> #include "Node.h" #include "SortedNumberList.h" using namespace std; void PrintList(SortedNumberList& list); vector<string> SpaceSplit(string source); int main(int argc, char *argv[]) { // Read the line of input numbers string inputLine; getline(cin, inputLine); // Split on space character vector<string> terms = SpaceSplit(inputLine); // Insert each value and show the sorted list's contents after each insertion SortedNumberList list; for (auto term : terms) { double number = stod(term); cout << "List after inserting " << number << ": " << endl; list.Insert(number); PrintList(list); } /* // Read the input line with numbers to remove getline(cin, inputLine); terms = SpaceSplit(inputLine); // Remove each value for (auto term : terms) { double number = stod(term); cout << "List after removing " << number << ": " << endl; list.Remove(number.

(Parent reference for BST) Redefine TreeNode by adding a reference to a node\'s parent, as shown below\': Reimplement the insert and delete methods in the BST class to update the parent for each node in the tree. Add the following new method in BST:/** Returns the node for the specified element. * Returns null if the element is not in the tree. */private TreeNode getNode(E element)/** Returns true if the node for the element is a leaf */private boolean isLeaf(E element)/** Returns the path of elements from the specified element * to the root in an array list. */public ArrayList getPath(E e) Write a test program that prompts the user to enter 10 integers, adds them to the tree, deletes the first integer from the tree, and displays the paths for all leaf nodes.

Great Pumplins: When growing giant pumplins for competitions, growers need to keep track of the weights of the pumplins while they are growing. It is difficult to weigh a large pumpkin before it is harvested, so a method has been developed for estimating the weight. The grower measures around the pumpkin both horizontally and vertically, then adds the results. This is called the OIT (over the top) measurement and is used to predict the weight of the pumplin. Following are the orT measurements and actual weights of the 10 largest pumpkins entered into official competitions in a recent year..

I)genealogical research is producing pedigrees for large families II)alleles causing trait variation are in linkage disequilibrium with alleles in the founding linkage III)All loci in the genome will reach linkage equilibrium after a small number of generations IV)alleles causing trait variation are in linkage equilibrium with alleles in the founding linkage.

Hippo signaling is a conserved pathway that controls cell prolifcration, apoptosis (cell death), and organ size in response to cell density. At low cell density (Figure I, on the left), transcription co-activators YAP and TAZ enter the nucleus and induce expression of genes that favor cell growth and proliferation. As cell density increases (figure 2 on the right), interactions between membrane-bound FAT4 receptors and DCHS 1/2 on neighboring cells trigger activation of cytoplasmic kinases Mst l /2 and LATS1/2. These kinases phosphorylate TAZ/YAP and prevent them from entering the nucleus, thereby reducing gene expression. 27. What is the ligand in this pathway? 28. What is the receptor in this pathway? 29. What are the target proteins in this pathway? What type of proteins are these (we've seen these in class during Week 3 )? 30. What happens when the target proteins are phosphorylated? 31. What is the ultimate cellular response if this pathway is activated?.
