The new strain may spread rapidly due to its increased transmissibility, meaning it can more easily infect individuals. This can result in more cases and faster spread within a population. Additionally, if the new strain causes more asymptomatic cases, infected individuals may unknowingly spread the virus more widely.
An old strain of DNA refers to the original sequence of genetic code, while a new strain refers to a mutated or altered version of the DNA. Mutations in the DNA sequence can lead to differences in characteristics or functions of an organism.
Nonnative animal populations can grow rapidly in new ecosystems because they may lack natural predators or competitors in the new environment. Additionally, they may be well-suited to take advantage of the available resources and reproduce quickly, leading to an increase in their population size. This rapid growth can disrupt the balance of the ecosystem and threaten native species.
i dont know how to explain it so i will give an example: a guy goes to this guy and sneezes on him then that guy will go crazy and he starts going crazy then jumps off a cliff and lands on someone then sneezes on him and he does the same thing the other guy does and it goes on and on and on.
Mites that can jump may pose a greater threat than those that cannot, as they may have an increased ability to move quickly and spread to new locations.
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
Improvements in communication.
Through mutation of an existing virus into new forms. Usually, there is mutation of the protein coating of the virus that results in a new strain. The new strain may or may not be infectious to the same group or organism that was vulnerable to the original virus strain. For a case example of how new viruses form, see the related question below that explains in detail what caused the new 2009 Pandemic Swine Flu virus. Also see the related question about the Lytic Cycle, which is the process that viruses use to attach to cells and reproduce.
The brushtail possum has no natural predators in New Zealand. This is the main factor which has enabled it to spread to almost plague proportions.
After its arrival in the New Work area,, the virus spread rapidly across the United States, as well as northward into Canada and southward into Mexico.
It provided the means to rapidly provide the news to the public. Pamphlets that contained new ideas and concepts, position papers, public notices and rallying cries were rapidly spread accross the country.
The 2009 H1N1 pandemic swine flu was a new subtype of Influenza A that had not been seen before in humans and it was thought that there would be no resistance from being exposed to it before or a virus like it before. Since there was no immunity "built in" and because this virus happened to be a very easily spread virus, it did spread widely and rapidly. Luckily, it was not as severe a flu as anticipated, therefore, the mortality rates were lower than was initially feared. Now that there is a vaccine (it is included in the 2012-2013 seasonal flu vaccines again), and more people have had this type of flu to build antibodies, it will have less potential to spread as rapidly again, unless it mutates to a new form as influenza viruses readily do, then we may have "cross-immunity" or it may mutate into a new form that our antibodies are not pre-prepared to fight.
Fungi grow rapidly by absorbing nutrients from their environment and expanding their network of hyphae. This growth is supported by optimal conditions such as moisture, nutrients, and suitable temperatures. As fungi grow, they produce spores that can spread and colonize new areas, allowing them to rapidly propagate and cover large areas.
Viruses spread through various modes, including direct contact with infected individuals, respiratory droplets from sneezes or coughs, contaminated surfaces, and bodily fluids. They can spread rapidly due to factors like high transmission rates, asymptomatic carriers, and social behaviors that facilitate contact, such as close gatherings. Environmental conditions and the virus's ability to survive outside a host also play significant roles in accelerating its spread. Additionally, global travel can quickly introduce viruses to new populations, further enhancing their transmission potential.
What was the effect of Johann Gutenberg's new machine?The effect of Johann's new machine was because ideas spread more rapidly. Books dropped drastically in price. Also Literacy rates increased.

"Saying 'spread your wings as a new nation' generally means to embrace freedom, independence, and growth as a new country. It may symbolize breaking away from the past and exploring new possibilities."
