Abstract: This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were
Article 4-Ecology Keyword- Ecology- Citation 1. Summary- The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article
If I had lived during the Holocaust, the hardships would include lack of shelter, starvation, and survival. To start, people struggled to find a safe shelter. The book Milkweed is about a boy who has to change the locations of his shelter to be able to survive. I know that during this time period a lot of people who were jewish were taken to concentration camps were they were forced to work and were treated harshly. Because of this people had to change the location of their shelter to escape getting caught. Additionally, people also had to face the struggles of starvation. Since hitler and his nazis were killing off a lot of people, the people who owned food stores could no longer sell food. This meant that people couldn’t get the same amount
Eastern Woodlands The name of my tribe is the Eastern Woodlands. The location of my tribe is in the Southeast portion of North America. The Eastern Woodlands have more than one tribe. Two of them were called the Mohawks and Huron. The Eastern Woodlands covered up the East Coast of North America from the Atlantic to the West of the Mississippi River. This is some of the information about my tribe called the Eastern
1. What was the original habitat of the organism? Japanese knotweed is native to Eastern Asia and was originally brought from Japan, China and Taiwan.
Once upon a time there was a marshmallow town called Marshmallandia. From at times there would be crimes made in the town by super villains called marsh masters. The Marsh masters would try to destroy the village until one-day baby Mellow was born and he grew up to save the world from the Marsh masters. It was noon at the time of the death of the hero Mellow. Mellow was only 4 in human years but 24 in marshmallow years. The hero mellow was trying to defeat a kid the marsh masters until they pulled fire out and melted him. ( physical change ) Marshmallow people came running from a village up close and froze him back to normal. ( physical change ) The marshmallow was going back home until he felt something lift him up, he looked and seen
As I am reading this story, I questioned whether Calipurnia or Aunt Alexandra is a better mom. I think Calipurnia is a better mom for many different reasons. She puts more time into the kids than Aunt Alexandra, and she genuinely cares for the kids and wants to keep them safe. To start off with, Calipurnia puts a lot more time into the kids than Aunt Alexandra does. On many occasions Calipurnia has made things for Scout and Jem to eat or drink like a mother would. For example, she said, “she did give Jem a hot biscuit-and-butter which he tore in half and shared with me” (Lee 137). This shows that not only would Calipurnia make their every meal, but she would sometimes give the kids some snacks while she was cooking in the kitchen too. In addition, Scout said that, “We skulked around the kitchen until Calipurnia threw us out” (Lee 137).
During the Holocaust, many townspeople didn’t bother coming outside and sat as bystanders peering out the window as their Jewish friends get lined up outside. Jews were herded up then murdered like sheep unknowing of what’s gonna happen until it happens. Although everyone acted as sheep, it was that they were fed lies about Jews, they didn’t see any harm until it was too late, and they didn’t want to be killed.

Although agmatine was discovered in the early 1900's, it is still not a well known substance yet. The reason for this is that most of the studies pertaining to it have only been done on animals. But very little of the research has been tried out on a group of
Riparian areas have been steadily declining across the United States in both area and connectivity (Oregon Department of Fish and Wildlife). Development and water use has significantly altered many stream and river systems in the US. Riperian areas are important for songbirds, erosion prevention, fish & invertebret habitat, trapping sediment and creating primary production. Restoring riparian areas can lead to an increase in biodiversity because there are a lot of organisms who specilize in using or living in riparian areas.
Range.—Giant milkweed is native to West Africa as far south as Angola, North and East Africa, Madagascar, the Arabian Peninsula, southern Asia, and Indochina to Malaysia (Rahman and Wilcock 1991). The species is now naturalized in Australia, many Pacific islands, Mexico, Central and South America, and the Caribbean islands. Ecology.—Giant milkweed favors open habitat with little competition. This condition is most completely met in overgrazed pastures and rangeland. Other common habitats are beachfront dunes, roadsides, and disturbed urban lots. The species grows in dry habitat (150 to 1000 mm precipitation) and sometimes in excessively drained soils in areas with as much as 2000 mm of annual precipitation. Giant milkweed may be found in areas
