Answer:
<u>the bottleneck effect</u>
<u />
Explanation:
Genetic drift has an important impact on the small populations. mutations, which are spontaneous heritable changes in the genetic code, made up of DNA. Here, mutations accumulate over time in a group, modifying the distribution of alleles or various forms of a gene. Natural selection may result in a loss of diversity in a population called genetic drift; one trait's allelic frequency rises while others become less prevalent. Typically such differences exist because of occurrences of mutation and recombination.
Some mutations or alleles may become extinct from the population.
<u />
Variants of a gene accumulate and are transmitted across generations; the frequencies of these occurrences are altered and become more stable in genetic drift- they become genetically distinct and may eventually form a new species after isolation. This may be further compounded through other phenomena such as the founder effect where a group separates and genetic diversity decreases; and the bottleneck effect where barriers to reproduction or the die-off a population increases genetic drift.

They were imported from China into the United States in 1881.
The first successful release was in Minnesota in 1916.
Hope this helps! :)
Because the air freshener is being released out in to open, so it spreads everywhere.
Hope that helps :)
You forgot to put the options, but i believe it is magma.
Two pieces of cardboard one located at the bottom and one on top joint by card board with balls at the bottom and top all joint. hope you can picture that, it's rather confusing, sorry.
Hope this helps
