If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.

Answers

Answer 1

Answer:

Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.

Explanation:

1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.

2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may  impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would  have lesser chances of entering the host cells and may or may not replicate.

3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.

4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

(hope this helped if ya need more dm me on discord AkashTheMissle07#3880)

Explanation:

0.3 year ago is three hundred thousand year ago and 0.2 year ago is two hundred thousand year ago.

What is year?

Every planetary body has an orbital period, it is called as a year. when earth complete its one orbit around sun, we call it a year. Due to earth's axis, we experience seasonal changes throughout a year.

The earths rotation period is approximated into number as calendar. The modern calendar is called as Gregorian calendar represents 365 days of year, or 366 days of a leap year.

To denote period, loosely associated with it, year is used. Most civilized types of calendar used are Gregorian calendar, it uses two notions, to indicate numbering of year, AD is short form of "Anno Domini" (meaning "in the year of the Lord"), and CE is short form of "Common Era".

So basically 0.1 million year refers to 1000 000 year ago, therefore 0.3 year is 3000 000 and 0.2 is 2000 000 years.

Transcription is A. The process of making RNA from DNA. B. The activation of a gene that produces proteins. C. Irreversible changes to the DNA sequence. D. The process of making proteins from RNA

Answers

Answer: A. The process of making RNA from DNA.

Explanation:

The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.
