Answer:
It would be so difficult to spend a life without computers. We would not be aware of technology or what things are being discovered. We could get information by newspaper, television, radio or some other medium but on computers.
Explanation:
Thanks for the points have a good day <3
False ( it's never safe to enter personal information into a pop window cause hacker always around us)
Answer:
5400
Explanation:
- As there are three spaces to be filled. First can have any alphabet, but not i and o. And there are 26 alphabets so, only one out of 24 can be filled in the first blank.
- In the second blank any alphabet can be used, but not the one same as the first one so we can choose from the remaining 25 alphabets.
- In the last blank any number can be chosen, but not 0 so we have 9 options to choose from.
Finally,the number of options available is <em>24*25*9 = 5400</em>. So, 5400 license plates can be made using these combinations.
<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>
False. The World Wide Web is NOT a program. It is the internet itself.
