Answer:
If there is a change in the environment, the particular species which does not manage to adapt either tries to translocate to a different habitat or it perishes. Adaptation requires a long time and does not happen overnight so if there is an option of moving out the animal adapts to do so. If that doesn’t happen we are looking at local extinction of the concerned species. This is one of the reasons why we are facing extinction of several species in our times. The rate at which we are changing the characteristics of habitats and even wiping out certain pristine habitats is leading to extinctions.

Explanation:
Natural selection is an occurrence in nature in which organisms with genes that have mutated to adapt to certain ailments, survive better than their mates. J.B.S Haldane made a hypothesis that this phenomenon of natural selection accounted for why people in Africa had developed resistance to malaria. Their hemoglobin, proteins, and other compounds that are necessary for the function of the red blood cells had been modified so that they would not easily be infiltrated by malaria parasites.
A.C. Allison confirmed this in his experiment which showed that people who had sickle cell mutations in the gene, beta hemoglobin were mostly found in regions where malaria was prevalent. Their genes had also been modified such that they were resistant to malaria.
Answer:
Pasteurization is the process by which food products (such as juice and dairy products) are mildly heated to kill off harmful bacteria, salmonella, and other disease-causing pathogens. These products are thus made safe for consumption. ... Pasteurization has revolutionized food safety within the dairy industry.

I think the correct answer from the choices listed above is option A. The function of arteries, veins, and capillaries in the circulatory system is that a<span>rteries generally carry oxygen-rich blood away from the heart; veins generally carry oxygen-depleted blood back to the heart; capillaries deliver blood to individual cells.</span>
