Answer:
The answer is B hierchary protocal
Answer:
Attached are screenshots of the working code - baring in mind this only works on mutable Collection types. (ones that can be changed) if you use Collections that don't support this you may experience an Unsupported Operation Exception - but this is expected.
Explanation:
Using Java streams as an alternative for some answers.
Answer:

Explanation:

Answer:
<u>Output</u>
The values read are:
25
3
4
65
7
9
5
6
1
11
10 data values were read
Explanation:
Below is the Java program to read all data from the file echoing the data to standard output and finally displaying how many data were read:-
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class MyFileReader {
public static void main(String[] args){
int num,counter=0;
File file=new File("numbers.txt");
try {
Scanner input=new Scanner(file);
System.out.println("The values read are: ");
while(input.hasNext()){
num=input.nextInt();
System.out.println(num);
counter+=1;
}
System.out.println(counter+" data values were read");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
<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>
