Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

Name: Rodrigo Alba Date: May 22‚ Global Warming and how it is affecting the Arctic Tundra The Arctic tundra is a region in the Northern Hemisphere that encompasses areas such as Canada‚ Alaska and much of Siberia in Russia. The word tundra refers to a vast treeless plain and is thought to have been adopted from the Finnish word tunturia (Arctic). Tundras are characterized by permanently frozen ground cover known as permafrost. The Arctic tundra is characterized by low precipitation and

enables it to function in biofilm production. Besides‚ Pseudomonas putida acts as an agent for plant growth and plant pest control. The complex interaction between Pseudomonas putida and Saccaromyces cerevisiae together regulate plant health. It is a mutualism between the prokaryotes and the plant. This is because prokaryotes produce sideospores such as pyoverdine and pyochelin to protect the plant from fungal

The Rainforest Ecosystem ENV 100 April 15 2013 The Rainforest Ecosystem “In an average year in a tropical rain forest‚ the climate is very humid because of all the rainfall‚ which amounts to about 250 cm per year” ("Discover The Rainforest "‚ 2011). The rain forest has large amounts of rain because it is very hot and wet. Tropical rainforests are defined by rainfall. They would not survive without it. Not all rain forests have tropical sunny

study of the community which is a group of organisms including animals and vegetation that tend to occur together. Field studies that monitor owls review the relationship between the environment‚ predator and prey. 5. How does mutualism differ from commensalism? Mutualism is an example of when both members/participants benefit from the partnership. In the example given in the video a commensalism relationship may be a hole in a tree and an owl living in it. The owl benefits the
