How do you explain how copies of viruses are produced?
copies of viruses are produced because some viruses stay inside there host cells.
Which microbes do not need to multiply inside of living cells?
They are called parasites. Some bacteria, fungi etc
Do all viruses have an envelope?
No. I don't think so.
Microbiology If there were no plaques on your plate offer an explanation?
Because viruses cannot multiply without a host cell, they cannot be grown in sterile media the way bacteria can. Host cells must be provided for the virus to infect. Bacteriophage may be cultured with bacterial cells in liquid culture or on plates. To culture on plates, bacteria and bacteriophage are combined in melted agar and then poured into plates. The bacterial cells divide and evenly cover the surface of the plate forming a lawn. Wherever bacterial cells have been destroyed by the bacteriophage, clearings called plaques will appear in the lawn. Because it is harder to culture animal cells than it is for most bacteria, it is also more difficult to grow animal viruses in the lab. Some animal cells will grow in culture dishes much as bacteria do and will form a single layer on the bottom of a dish that contains a suitable growth medium. Viruses that can infect these cells can be grown along with them. Animal cells that are infected by the virus will display visible deterioration. Some viruses whose host cells can not be grown in culture can be grown in living animals such as rabbits, mice, and guinea pigs. Other viruses can be grown in fertilized chicken eggs. However, because some viral host ranges are highly specific, each virus infects only certain cell types, I cannot grow all cells in culture, yes grow all viruses.
What types of organisms does bacteriophage attack?
Bacteriophages are viruses that infect the cells of bacteria. For this reason they are commonly used as alternatives for antibiotics in some countries.
Is some viruses are prokaryotes and some are eukaryotes?
Viruses are neither prokaryotes nor eukaryotes as they are not living cells and do not have cell structure. They are parasites of living cells.
What are some things that might damage cells?
viruses
How do you explain how copies of viruses are produced?
copies of viruses are produced because some viruses stay inside there host cells.
Are all viruses made out of a cell or cells?
Viruses are made of nucleic acids; some also have a protein shell.
Can some RNA and DNA viruses change healthy cells into cancerous cells?
true
How can you trick your parents into letting you do something?
You can trick your parents into letting you do something by telling them it will be educational or will benefit them in some way. An example would be to say a movie would help to better understand history when it is in fact totally unrelated to history.
What are some limitations of antibiotics?
One thing is that antibiotics cannot kill viruses, as viruses are DNA structures which enter the cells in your body in order to duplicate, however antibiotics cannot enter into the cells, and can therefore not stop the virus.
How can you kill viruses?
There are numerous products that kill viruses on environmental surfaces, but few that safely attack them in the body. The body's "T helper cells" can signal macrophages to attack some viruses.
Do virused have cell walls?
NO
What compounds kill bacteria cells and some viruses on the skin?
Antibacterial ointments, like Neosporin.
How do viruses reproduce compared to bacteria?
Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host.A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more detail of the process of reproduction of some viruses inside body cells.
Is the spanish influenza virus single celled or mulitcellular?
Neither. Viruses do not have cells but are surrounded by protein capsids containing the viral DNA or RNA. Some viruses have glycoprotein coats that they take from the membranes of cells they preform lysis on.
