Scientists have put genes into potato plants to make vaccines against cholera and hepatitis B  this type of research is called

It’s late summer and a new influenza virus strain has appeared in chickens across the country.It’s an H1N1 strain of Influenza A, like the Spanish flu that caused one of the deadliest pandemics in humanhistory, back in 1918. In that case too it started as an avian flu that mutated and jumped directly from birdsto humans.You are a researcher at the NIH and the President gives you 24 hours to predict the chances that this couldturn into the next “Spanish flu”. They also ask you to present a plan for a vaccine that will specifically targetthis new strain.The full sequence of the Spanish flu virus is available and is also known which mutations where key toconfer it both high infectivity and high virulence. Also the frequency of mutations of this family of viruses isknown.Samples of the new strain currently infecting chickens are also available to you.You are at the NIH laboratories in Bethesda, MD, and you have infinite resources (equipment and staff) atyour disposal.Remember: Influenza…

In 1554, a cholera outbreak occurred in London.  Cholera is a disease that causes intense diarrhea and can be fatal.   At the time, many people believed that diseases were caused by “bad air.”    John Snow had another idea; he thought that cholera was caused by something in the environment where people lived.   He went door to door and made a map showing households that had cholera.  He found that most of the cases were near the Broad Street Water Pump.    John Snow made a case that the water from the pump was making people sick and the pump was shut down. REASONING:   If water was the cause of the sickness, then

Prions are tiny circular molecules of RNA that can infect plants mobile segments of DNA viral DNA that attaches itself to the host genome and causes disease misfolded versions of normal proteins that can cause disease

A new medication has been found that can stop the spread of a disease significantly by a process that does not allow the virus to leave the infected person's body. Patients who do not take the medication have very high transmission rates. The Center for Disease Control and Prevention (CDC) randomly selected participants for a study and divided them into two groups. The first group received the medication and the second group did not. The CDC has concluded that the medication could halt the spread of the disease. Which statistical study did the CDC most likely use?  a They most likely used a sample survey that asked patients who took the medication whether they came in contact with someone who had the disease. b They most likely used an observational study that observed patients, selected at random, to determine whether those patients who took the medication spread the disease to others. c They most likely used an experimental study under controlled circumstances on…

Which animals are most important for research to combat disease in humans?     Rabbits   Mice   Guinea Pigs   Rats   All of the above

Why is it so hard to get rid of the following organism? They undergo bottlenecking in their populations when taking antibiotics? They gain plasmids that help them build resistance. Using antibiotics are ineffective. They come from mosquitos and they are abundant. Part of their life cycle includes zoonosis with snails.

Can you elaborete in detail about Natria Neem Oil spray which is a pesticide spray that is considered to be an organic disease control spray against aphids.

Viruses are not typically considered living organisms because they contain no biological molecules like lipids and proteins they can not replicate or reproduce on their own they do have any genetic material (DNA or RNA)

Nelson uses the analogy of a cracker with peanut butter to describe colonized leaves. Which component of the system does the peanut butter represent?
