Why is it important to use a weakened virus in a vaccine?

PolarNik [594]2 years ago

If you used a full active virus, that defeats the point of a vaccine. You will trigger your immune response, but since you would just be injecting the virus, it will make you sick, and your body will be less effective at fighting the pathogens.

Viruses in vaccines are weakened, so they essentially will not "fight" back. They most importantly just contains the antigen markers so the body can trigger the immune response, quickly eradicate the pathogen, and build up the memory cells to that virus.

Injecting a virus that is not weak will just be the same thing as if you got the virus, you will likely get sick.

Q8. Design an experiment that you could perform to see if a population of fruit flies—very small insects that feed on bananas—gr
ra1l [238]

One experiment that we could use to test the way in which fruit fly populations grow is to enclose a set amount inside a container with a food source and measure the population growth daily, then repeat this many times.

In order to test the way in which the fly population grows, we need an experiment that will allow us to gather data at set intervals. To do this we can create an experiment in which we set up multiple enclosures, each with a set amount of flies and one banana. Then measure the population on a <u>day-to-day</u> interval.

By performing the experiment with multiple enclosures, we can not only confirm that the results are accurate by having tested it many times, but we can also take the opportunity to test the effects of the food supply on population growth by adding more bananas and seeing if the population will increase at a different rate than the other enclosures.

Once a set number of days have passed, and we have the data corresponding to the population size each day, we can proceed to graph the data. Once graphed, we can analyze the data shown in order to observe whether the population is growing logistically or exponentially.
