private static int calculateNumberSum(int[] arr, int index)…

private static int calculateNumberSum(int[] arr, int index) is a recursive helper method. It is used to calculate and return the sum of all the numbers in the given array, from the specified index to the end. Implement the calculateNumberSum(int[],int) method by filling in the blanks. You don’t need to consider scenarios where arr is null or index is negative. private static int calculateNumberSum(int[] arr, int index) {    if (____________1____________) {        return ____________2____________;    }    return ____________3____________ + calculateNumberSum(____________4____________);} Use this template for your answer (please type fully – you cannot copy): 1: [answer to blank 1] 2: [answer to blank 2] 3: [answer to blank 3] 4: [answer to blank 4]

Look at the following code (it is the same as the previous question): // [All the necessary imports here, omitted]public class FinalExamApp extends Application {    private ArrayList winterPlans = new ArrayList();    public void start(Stage stage) {        stage.setTitle(“Final Exam App”);        Label label = new Label(“Winter Idea: “);        TextField textfield = new TextField();        Button button1 = new Button(“Add Idea”);        Button button2 = new Button(“Sort Plan”);        // Code for buttons will be here        VBox root = new VBox();        root.getChildren().add(label);        root.getChildren().add(textfield);        root.getChildren().add(button1);        root.getChildren().add(button2);        Scene scene = new Scene(root);        stage.setScene(scene);        stage.show();    }} Using a lambda expression, implement the functionality of button2 such that it sorts winterPlans when pressed. Please use Collections.sort to sort your list.

Use the following scenario to answer the question below:  Joe’s biology class was studying the effects of different wavelengths of light on the process of photosynthesis in bean plants.  Four flats of bean plants (25 plants per flat) were grown for five days. The plants were then exposed to different colors of light as follows: Flat A was placed under red light; Flat B was placed under blue light; Flat C was placed under green light; and Flat D was placed under white light. The plants were exposed to the same temperature conditions and received the same amount of water and carbon dioxide each day. At the end of 20 days, the students recorded the height of the plants in centimeters. What was the independent variable in the experiment?
