How can a disease transition from a basic illness to a flown blown pandemic​

Biology
1 answer:
eimsori [14]2 years ago
3 0

Answer:

Pandemics occur for two reasons. The first is a change in the infectious agent and the second is in human patterns. Both involve exposing people to agents they don’t have resistance to. Diseases like SARS, avian flu, and the famous Spanish flu all involved a mutation in the virus that resulted in a new disease that no one had resistance too. Examples of the second are when new groups of humans make contact, like small pox amongst native Americans, and possibly the black death.

Explain e.o. wilson’s theory of island biogeography as it applies to environments other than islands physically surrounded by wa
laiz [17]

Today, any environment surrounded by other ecosystems that are unlike it is subject to Wilson’s theory of island biogeography. Because they are geographically isolated from other related ecosystems, these ecologies are referred to as "islands." Waterbodies divide tropical islands, but this idea also takes into account mountaintops, caverns, and other isolated ecosystems.

<h3>What is Wilson’s theory of island biogeography?</h3>
  • The biologist Edward O. Wilson and environmentalist Robert MacArthur published The Theory of Island Biogeography in 1967. It is widely considered as a foundational work in the ecology and biogeography of islands. The book was reissued by the Princeton University Press in 2001 as a volume in their "Princeton Landmarks in Biology" series.
  • The hypothesis that insular biota maintain a dynamic equilibrium between extinction and immigration rates was made more well-known by the book. An island's pace of new species immigration will decline as the number of species increases, while the rate of extinction of native species will rise.
  • Thus, MacArthur and Wilson anticipate that there will come a point of equilibrium where the rate of immigration and the rate of extinction are equal.

Plasmids are small circular DNA molecules found in bacteria that replicate separately from chromosomes. Why are plasmids essenti
oksano4ka [1.4K]

Answer:

DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times.

Explanation:

Plasmids are the extra-chromosomal circular DNA present in bacterial cells. Plasmids are able to replicate themselves independent of genetic DNA. Their ability to self replicate allows them to maintain themselves in the bacterial cells. This is why plasmids are used as cloning vectors in recombinant DNA technology.

A gene of interest is isolated from the donor cell and is inserted into the plasmid. The recombinant plasmid is introduced into bacterial cells where it replicates the ligated desired gene and allows the gene cloning. For example, the human insulin gene is ligated with plasmid and the recombinant plasmid is introduced in <em>E. coli</em> where it replicates the human insulin gene and allows the production of desired copies of the gene.
