Do you think it demonstrates that scientists may lose their objectivity when they want data to fulfill their expectations and desires or does it demonstrate the self-corrective nature of science? Why were people so willing to believethat one of the oldest specimens was found in south England?
- The idea for “Earth Day” was proposed by ______.Long ago, many people believed that living things could come from nonliving things. They thought that worms came from wood and that maggots came from decaying meat. This idea was called spontaneous generation. In 1668, an Italian biologist, Francesco Redi, did experiments to prove that maggots did not come from meat. One of his experiments is described below. Redi placed pieces of meat in several jars. He divided the jars into two groups. He covered the first group of jars with fine cloth. He left the second group of jars uncovered. Redi observed the jars for several days. He saw flies on the cloth of the covered jars, and he saw flies laying eggs on the meat in the uncovered jars. Maggots appeared only on the meat in the group of jars left uncovered. What was the question in Redi's experiment? O Is spontaneous generation a valid explanation for maggots in meats? O How do maggots appear in meats? O Are jars a good place to grow maggots?Why are the protists in termites obligate endosymbionts? question # 8
- Why is it hard to create a timeline of events chronicling Earth’s History?A ship was caught in a storm and landed on a small island in the middle of the South Pacific. For generations, no one encountered this small colony who, despite the odds, made a thriving settlement on their island. After many years, what characteristics would be unique about this island population? a. The people would look very different from each other, and may have evolved some odd characteristics that aren't seen in other humans. b. The people would look very different from each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. c.The people would look very similar to each other, and may exhibit abnormally high occurrences of genetic diseases that are rare in the general human population. d. The people would no longer be considered humans after evolving independently for several generations.Brazil is home to some of the most remote tribes in the world. Many of these people have not had any contact with the outside world. The Yanomami tribe is roughly 19 000 individuals, making it one of the largest tribes in the Brazilian amazon. Their land mass, which is slightly smaller than Hungary, has provided them with a wealth of resources from the forest to survive in the past. Currently, the tribe is losing land to development for mining and ranching. The Yanomami are very isolated from other tribes. As a result, individuals form tight family groups who support each other for their whole lives. The Yanomami practise polygamy, where men will have a number of wives during their lifetime. The women in the tribe are only married to one man. Based on the above information, why do the Yanomami NOT qualify as a Hardy–Weinberg population? a. The communities migrate during the seasons and marriages are with more than one individual. b. They are not a closed population and mutations…
