Why is there a cornavirus?

Some people have the cornavirus in this state and in this country.

Well in my opinoin it just  turned on  in one person got sick now it's spreading

Step-by-step explanation:

Several of the early cases had visited Huanan Seafood Wholesale Market and so the virus is thought to have a zoonotic origin. The virus that caused the outbreak is known as SARS‐CoV‐2, a newly discovered virus closely related to bat coronaviruses, pangolin coronaviruses, and SARS-CoV.

The scientific consensus is that virus has a natural origin. The probable bat-to-human infection may have been among people processing bat carcasses and guano in the production of traditional Chinese medicines.

There is a caronavirus because of us "human" this virus was mas made and created by man. This was all created because of over population. The Earth is dying and that means we will also die. So humans thought that if the amount of people on Earth went down then we would have a chance to survie. However this backfired because it is spreading and they have no idea how to cure it and or stop it from spreading.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
