What are the various methods that might be used to inactivate or eliminate chlorine-resistant viruses?  One of these viruses is Cryptosporidium as an example

You have a petri dish containing 1 x 106 adherent cells. You have a vial ofpoliovirus with a concentration of 2.8 x 107 pfu/ml. How much volume of the stockvirus should you add for an MOI of 1.0? MOI means: multiplicity of infection

Provide research information on zanamivir (antiviral drug) and determine the mode of action. Be sure to include the class of virus being targeted and how they replicate to explain the mode of action. AND Mechanisms

In a case study, scientists frequently infer that Malignant transformation of hymenolepis nana in human host occurred because of the patient’s HIV/AIDS status and resultant immunocompromised state. When N=1, is such an inference statistically justified? In addition to Yes or No, jot down your thoughts on the possible association between AIDS and this case.

The epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak – an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together. Some general changes within these three factors that may cause an infectious disease to emerge include:     A. changes in populations or behavior of reservoir hosts or intermediate hosts   B. microbial genetic mutation and viral genetic recombination or assortment    C. environmental factors such as an increase in precipitation   D. all of the above    E. none of the above

Which link in the chain of infection is the intervention described below meant to break? "Quarantine is used to keep someone who might have been exposed to COVID-19 away from others. Quarantine helps prevent spread of disease that can occur before a person knows they are sick or if they are infected with the virus without feeling symptoms. You have been in close contact with someone who has or is suspected to have COVID-19 so it is important for you to stay home, separate yourself from others, and monitor your health." http://publichealth.lacounty.gov/ acd/docs/COVHomeQuarantine.pdf Susceptible host Infectious agent O Portal of entry O Means of transmission

Please introduce how to obtain a nucleotide sequence of unknown viruses. Please give me a detailed process.

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.

The genus of bacteria with leaky cell walls which are transmitted among humans by direct contact is:

Discuss either (a) how allelopathy contributes to the invasiveness of spotted knapweed or (b) the difference between choice and non-choice experiments and how it relates to experiments on hyperaccumulating plants.
