<span>A) All viral genomes contain both DNA and RNA. FALSE. Viruses contain the smallest necessary amount of genetic information packaged in a capsule composed of proteins. Containing both DNA and RNA would be a redundancy that would unnecessarily increase the size of the virus and make it more difficult for the virus to penetrate a cell. B) A retrovirus contains RNA. TRUE. By definition a retrovirus contains single-stranded positive-sense RNA instead of DNA. C) HIV contains two identical strands of DNA. FALSE. HIV is a retrovirus and, therefore, contains RNA instead of DNA. D) HIV contains reverse transcriptase. TRUE. HIV is a retrovirus that contains an RNA genome. All retroviruses require reverse transcriptase to convert their genome from RNA to DNA once the virus has been entered the cell. E) The capsid enters the host cell if the virus is enveloped. TRUE. Viruses are to large to enter a cell by passive diffusion or active transport. The only remaining major form a transport into the cell is endocytosis, or being enveloped. F) All RNA-containing viruses are retroviruses. FALSE. By definition a retrovirus contains single-stranded positive-sense RNA. Viruses can contain RNA in other forms (ie double-stranded) and would, therefore, not be considered a retrovirus. G) Enveloped viruses bud from the host cell. TRUE. Viruses are to large to enter a cell by passive diffusion or active transport. The only remaining major form a transport into the cell is exocytosis. For a virus to exit the host cell and infect other cells, they must exit by exocytosis, or budding.</span>

Write a program that reads an arbitrary number of integer that are in the range 0 - 50 inclusive and counts how many occurrences
Anna [14]

Answer:

Check the explanation

Explanation:

import java.util.Scanner;

public class Count

{

   public static void main(String[] args)

   {

       // creating array of store to store count of

       //every integer entered

       int[] store = new int[51];

       System.out.println("Enter any integers between"+

       " 0 and 50, and if you are done then enter any"+

       " integer out of the range");

       System.out.println("Enter Integer: ");

       //taking input of first integer

       Scanner scan = new Scanner(System.in);

       int integer = scan.nextInt();

       //looping for integers entered in range

       //to count its occurance

       while(integer >= 0 && integer <= 51)

       {

           //adding count to 'store' array of that

           //particular array of value entered

           store[integer] = store[integer] + 1;

           System.out.println("Enter Integer: ");

           integer = scan.nextInt();

       }

       //printing number of times each integer is entered

       System.out.println("printing number of times"+

           " each integer is entered");

       for (int i=0; i < 51; i++)

       {  

           if (store[i] > 0)

               System.out.println(i + ": " + store[i]);

       }

   }

}

Harlamova29_29 [7]

Answer:

Explanation:

In programming an array is simply a grouping of various pieces of data. Various data elements are grouped together into a single set and saved into a variable. This variable can be called which would return the entire set which includes all of the elements. The variable can also be used to access individual elements within the set. In Java an example would be the following...

int[] myArray = {33, 64, 73, 11, 13};

In Java, int[] indicates that the variable will hold an array of integers. myArray is the name of the variable which can be called to access the array elements. The elements themselves (various pieces of data) are located within the brackets {}
