Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.

B) A single virus can infect multiple cells at the same time. C) Viral replication can exponentially increase virus numbers. D) Viruses destroy host cells upon their release from the cell. E) Viruses use their own organelles for replication of viral components.

Answers

Answer: A, C, and D

Explanation: i just did it on usatestprep

The arguments that are supported by the diagram depicting the lytic cycle of viral replication are as follows:

Viruses use a host cell to replicate their genome.Viral replication can exponentially increase virus numbers. Viruses destroy host cells upon their release from the cell.

Thus, the correct options are A, C, and D.

What is the Lytic cycle?

The lytic cycle may be defined as a type of cycle that involves the process of lysis and destruction of the infected cell and its membrane. This process occurs when a virus has completely infected a cell and replicates new virus particles by the activity of bursting the cell membrane.

The lytic cycle is considered one of the two cycles of viral reproduction, the name of the other is the lysogenic cycle.

During the lytic cycle, the virus uses a host cell to replicate its genome. After occupying the host cell for the same activity, viral replication can exponentially increase virus numbers. And finally the destruction of cells and release themselves from the cell.

Therefore, the correct options for this question are A, C, and D.

I thought about attending a performance at the citys amphitheater; however, the city will be in bedlam with the performance and the sporting event occurring simultaneously. MOM: I didnt find a worthwhile destination either. KENNETH: Ive concluded that we should embark on an exhilarating and exciting trip this yearsomething weve never done before. MOM: I dont want to dismiss your idea, Kenneth, but where can find such an awe-inspiring experience? KENNETH: I thought we could hike up Mount Whitneyits the highest peak in California. Because its located on the border of Inyo and Tulare counties, its also relatively close to home. Since were all strong athletes, I think that making the ascent is feasible. JEANNETTE: (to Kenneth) That sounds like an awesome and memorable trip; however, theres one problem with your planI suffer from acrophobia. KENNETH: (with a look of befuddlement) Acro- what? MOM: Acrophobiait means that Jeannette suffers from a fear of heights. The root word phobia, meaning fear of, comes from the Greek word phobos, which means fearing. Acrophobia is one of the most prevalent phobias in the country.KENNETH: (to Jeannette) I recall a few years ago when we traveled on an airplane to Aunt Janices houseyou were enthralled, peering out the window at the scene below.JEANNETTE: I did have a tremendous time on the airplane; however, after that trip, my phobia gradually progressed, and now merely thinking about flying evokes terror and makes me squeamish. For me, riding the elevator to the top floor of a tall building is much like trekking up Mount Everestits a gigantic feat of willpower. MOM: Sometimes the best way to get over a fear is to face it. Perhaps we should try to climb the mountain so that Jeannette can tackle her fear. Do you think it would intolerable for you, Jeannette?JEANNETTE: (with a look of trepidation) I dont believe I would be very excited during the ascent, and I may not reach the apex; yet, I would savor the astonishing panoramic views. But what if I lost my composure and chose not to climb with you? I would be loath to jeopardize your trip. DAD: Jeannette, were a family; we must always support each other. I believe that if youre brave enough to attempt the climb, we should be more than willing to stop if you feel overwhelmed or extremely uneasy. MOM: Just trying is an immeasurable accomplishment! KENNETH: Ill have a wonderful vacation as long as I get to view the noteworthy peak; everything else is secondary to me. Whats your verdict, Jeannette?JEANNETTE: The thought of scaling a gigantic mountain is both scary and exhilarating.

Summary essay of the movie radio What voltage produces a current of 100 amps with a resistance of 50 ohms? Parkour is thought by many to be an extreme sportespecially when people see parkour practitioners (known as traceurs) climbing walls and jumping off buildings. However, it might be better to characterize parkour as a radical art form involving both the body and mind. Although this art form can be extreme, it does not involve the teamwork, structure, or competitiveness of organized sports. In addition, traceurs can be difficult to recognize, as they do not wear matching uniforms to identify themselves. Parkour and its practitioners are in a category of their own. The ultimate goal of parkour is for a person to mentally and physically prepare to overcome any obstacle he or she may face. Traceurs, who pit their bodies against various types of obstacles, often risk physical injury, and safety is an important concern. While practicing parkour, a traceur's route may take him or her over a large boulder, across several rooftops, or across the top of a wall. As dangerous as these acts may sound, most traceurs do attempt to learn the safest way to move, jump, and land. Parkour has become a popular art form in urban settings around the world due to the many obstacles located around the cityscape. This has led to concerns for traceurs' safety, as well as worries about traceurs trespassing on private property and attempting to jump from high buildings. As in most physical activities, safety for oneself and others should be paramount in the practice of parkour. Which sentence from the passage best expresses the main idea of paragraph 2? A.
