Leya [2.2K]

Answer:

The correct answer is option d. "Polyclonal antibodies".

Explanation:

The enzyme-linked immunosorbent assay (ELISA) is very useful in comparison to other immunoassay methods for being highly accurate, sensitive and specific. Polyclonal antibodies for the detection step could be used on order to ensure that a mutation in a single surface protein would not make obsolete an ELISA used to detect a new viral pathogen. Unlike monoclonal antibodies, polyclonal antibodies are a collection of antibodies that recognize multiple epitopes of the same antigen. Therefore, a mutation in one epitope that affects the binding of one antibody would not affect the bind of the others and the ELISA will be able to recognize the pathogen.

Mashutka [201]

Answer:

Tornado

Explanation:

  • A cyclone:

A cyclone can last on average for 9 days depending upon the forces of wind leading to the decay of the things. It typically effects an area of  typically 30–65 km (20–40 miles). They are characterized by rotating winds around an area of low pressure.

  • A hurricane

It is a form of cyclone called a Tropical cyclone. It is characterized by heavy thunderstorms where winds circulate in a counterclockwise towards the center of earth. These vigorous winds destruct an area of 50 to 100 miles from the point of their origin. They can last from 12 to 24 hours depending upon the speed of wind.

  • A thunderstorm

A thunderstorm is a weather event that can manifest itself in different forms like lightning, Thunder and strong wind, rain, snow. It is a broad term that covers many events like Tornadoes, Floods,Cloud-to-ground lightning and hailing. Depending upon intensity the damage path of a thunderstorm can be from few miles to hundreds of miles.

  • A Tornado

A Tornado is a specific form of thunderstorm that are characterized by strong, rapidly rotating winds that damages a path from one to fifty miles. They last for less than ten minutes so we can say their duration is less than other deadly weather events.


Therefore, Tornado is best option.
