Which weather event is typically brief, contains very strong winds, and leaves a path of destruction up to 50 miles long? a cycl
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.

What is the difference between code, codon, and anticodon?
NeX [460]
The codon is a set of 3 nucleotides that can be read to convey a message in your DNA. It can be a code saying to "start" the process of protein synthesis, or "stop" it, or to encode for an amino acid - the building blocks of proteins. 
<span>The DNA is read, and proteins are made by DNA Polymerase (simple version here, it is more complicated, but this is the gist of it) travelling down the DNA. As it travels, it reads the nucleotides and builds a chain of amino acids, that corresponds to the information gleaned from the DNA. </span>
<span>So, the codon is only on one side of the DNA, and there are 2 sides. In order to be able to keep the DNA safe, and package it well (and loads of other reasons ) there is a complimentary strand. The nucleotides that make up DNA are A, T, C, and G. A links to T and C to G, and vice versa. </span>
So if your DNA strand's codons read "AAG AGG TCA"
Then the complimentary strand will read "TTC TCC AGT" the three codons on the complimentary strand ARE THE ANTICODONS of the codons on the strand being read (aka "expressed").
<span>So a codon and an anti codon are made of the same things, it just is a matter of which is being actively expressed. Now, this gets insanely complicated when you learn more about reading frames! Not only are there those codons, but if you shift and start reading the "code" either one nucleotide earlier or later, it completely changes the message.</span>
