Population extinction is a natural occurrence, but because the pace of extinction on a global scale is increasing, understanding extinction is crucial for conservation. To evaluate proposed extinction processes, the rate of extinction in experimental populations of brine shrimp (Artemia franciscana) was evaluated. As was predicted, the chance of extinction was decreased by a larger initial population, a larger maximum population size supported by the environment, and less change in environmental variables. However, contrary to popular belief, maximum population size and environmental variation were more significant than initial population size. Unexpectedly, the importance of deterministic population oscillations brought on by inborn nonlinear dynamics and overcrowding was equal to or greater than that of the assumed processes.
<h3>What is
extinction?</h3>
Extinction happens when species become endangered due to environmental factors such habitat loss, climate change, natural disasters, human overuse, and pollution, or because of evolutionary changes in its constituent parts.

Explanation:
we are required to fill in the blank spaces in the attachment.
protein side chains are non polar. so the first answer is non polar. These side chains are hydrophobic in nature. so the second blank is hydrophobic. Non polar substances are known to have large number of van der waal forces. the third answer is large and the fourth is vanderwaals contact. the protein core destabilizes only when there is a weakening of vanderwaals contact which brings about mutation.
dear user your answer should look like this:
<u>Interactions of non polar side chains in protein sequence lead to the formation of a tightly packed hydrophobic core. This core is stabilized by a large number of vanderwaals contact. When a mutation occurs, it destabilizes the protein core and weakens vanderwaals contact leading to misfolding</u>

<h3>
What is endangered species?</h3>
A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species.
Whooping Crane:
With its pure white plumage, scarlet crest, bugling call, and exquisite mating dance, the Whooping Crane is the tallest bird in North America and one of the most impressive. It is one of our rarest birds and a symbol of the perseverance and innovation of conservation biologists. The species' population fell to about 20 birds in the 1940s, but numbers have since increased to over 600 thanks to captive breeding, wetland management, and a ground-breaking program that teaches juvenile cranes how to migrate.
