When Jurgis visited the durham's meat packing plant she saw that the diseased meat were injected with chemicals, spiced and canned to be sold in the market. Some of the packers buy rancid butter and they oxidize it to get rid of the odor.The men working there were also inflicted with some disease. The butcher often get cut and work with the bleeding hand and contaminate the meat. the meat of different animals are packed and sold with the name of some other animals.
Hence, the trip to meat packing plant was horrible and pathetic. That was so unhygienic that after seeing the conditions there, it is impossible for a person to buy the meat and eat it with a trust.
Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
The correct answer is the first option.
It shows how a trait is past through family.
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
