Answer:
C.People can be tested for mutations on these genes
Explanation:
Answer
The ability of some fish, like clownfish, to detect predators is decreased in more acidic waters. A sudden drop in pH can as cause medical issues, such as comas and seizures in oceanic life. Fish's skeletons are also sensitive to acidity, so their development may be impacted as well.
Answer: Inflammation
Explanation: Inflammation, is caused by the dilation of blood vessels which allows the passage of fluid, antibodies and WBC's into the infected body area
Ans.
Sickle-cell disorder shows defected red blood cells, due to mutation in gene that code for hemoglobin. The mutated genes for sickle-cell disease are found in higher percentage of sub-Saharan African population as it provides protection against malaria as compared to population of United States.
Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.
On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.
Thus, the evolutionary process behind this is 'natural selection.'
