Immunizations work by pre-infecting the body so it knows how to produce the right antibodies as soon as the virus starts reproducing. Also, because viruses reproduce so quickly and so often, they can often change slightly. Sometimes, mistakes creep into their genetic instructions. These changes ...
Once inside a cell, viruses use the machinery of the cell to replicate themselves. MY LATEST VIDEOS Luckily for us the human body has lots of natural responses to protect us from viruses and other harmful pathogens. How does a virus enter the body? The human body has several lines of defe...
A driver might be found to have a level of 0.15, for example, while the legal limit is 0.08. To comprehend how we can gain access to such precise numbers, we have to ask ourselves: how does a breathalyzer work? What do those figures mean? And how do police officers find out if ...

So, HIV requires a host cell to stay alive and replicate. To reproduce, the virus creates new virus particles inside a host cell, and those particles carry the virus to new cells. Fortunately the virus particles are fragile. Viruses, including HIV, don't have cell walls or a nucleus. ...
1970s.7However, the virus was first discovered 2 decades earlier when monkeys in a research laboratory in Denmark were infected during an outbreak. That case inspired its name, but the natural reservoirs where this virus lives and reproduces are actually African rodents—monkeys a...
These critters can live up to two years in captivity but typically lead shorter lives in the wild. They can reproduce when they are just two months old. A female can give birth to a litter every 6-8 weeks; each litter averages between 2-12 baby mice. This means if you notice mouse ...
You must cover all areas of the curriculum, however, you must factor in your strengths, your weaknesses, and exam weights when developing your study plan. Given the breadth of the material, you must develop a study plan that maximizes your time. One fatal error is attempting to reproduce th...
If possible, tell us when the problem started and any steps to reproduce it. You can upload a file, such as a log file or output from diagnostics. For more information on file uploads, see File upload guidelines. In the Share diagnostic information section, select Yes or No. Selecting...
