Flu+Virus

1. Why are viruses not exactly living or nonliving? Because they are anticellular, ACELLULAR which means that they are not made up of cells and as a result canNOT live independently 2. Give some examples of diseases caused by viruses. Cold, Flu, Measles, Chicken, Pox, Polio, Rabies, Aids, Genital Warts, and Genital Herpes 3. What is the basic structure of a virus? (The two parts and their function) They contain an outer capsid which is made up of protein and an inner core made up of nucleic acid 4. Why are viruses like microscopic pirates? They control their host cell, and make it do whatever they want it to, due to this they are considered to be like pirates 5. Why are viruses considered parasites? Because like paracites they consist of a large group or clump of cells stationed in one area HARM THE HOST 6. Why are viruses considered OBLIGATE parasites? Because they can controle their host cells, and can manipulate other cells around them into doing whatever they want them to do THEY MUST HARM LIVING THINGS TO SURVIVE 7. Why do viruses ALWAYS cause disease? Because of the rapid way they can divide and spread through out the body in a quick period of time MUST HARM LIVING THINGS TO SURVIVE 8. How do viruses "emerge" and "spread" each year? Give examples. They are able to do this through animals such as bugs and flys that are in constant contact with humans. Through this virus' spread very quickly and can not be controled to some extent. Infected birds is where the flu comes from every year, and it somehow makes its rounds to lots of people before the year is over RAPID REPLICATION 9. What is a virus vector? Give examples, These are the animals that carry and spread the viruses around to ther people, such as flys or misquitoes. These take massive efforts to control by a population 10. What is the relationship of bird flu to birds? Infected birds get the flu, and as a result it spreads by people eating infected chicken or by virus vectors transmitting them to humans. The flu is such a dinamic disease that it can infect both humans and animals 11. How does bird flu infect humans? by the time it reaches humans it has been ginetically altered to survive in strands that will affect humans, so it makes it very hard to control 12. What is a pandemic? A Virus that can survive in both humans and animals 13. Why is there fear that bird flu could cause a pandemic? Because it has to ginetically be different to survive in both humans and animals 14. What action can we take to prevent a bird flu pandemic? Kill infected birds every year so the disease will not spread
