Explanation:
All Animals have EVERY right to a good quality of life! It is humans with a typical human arrogance that decide who lives, who dies, who is food and who is not and how they will live and be killed. We even have Animal Protection laws for dogs, cats and “pets” and farm animals are treated like dirt, having very few protections! If you did to your dog what you do to pigs you would go to jail! Discrimination and arrogance taken to the nth degree! Since humans subject Animals to the existence humans choose and nobody ever asked a cow, a pig, a hen or any other animal how they want to live their life I think it can qualify as “Slavery”.

Free-living flatworms ingest food
Explanation:
Ans.
Sickle-cell disorder is a genetic disorder, which shows defected red blood cells, due to mutation in the genes for hemoglobin protein.
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.
Hence, sub-Saharan African population shows higher percentage of mutated gene for sickle cell as compared to population of United States.
Thus, the evolutionary process behind this difference is 'natural selection.'
The answer is culinary. Hope this helps.
