The tundra ecosystem of Alaska is known as a “cold desert.” It receives very little precipitation, about four inches annually. However, it is rich in wetlands due to permafrost, which traps moisture close to the surface. The temperatures vary widely, also producing persistent winds. Although treeless, the Arctic tundra is an abundant ecosystem. Many organisms find their niche here including many migratory bird species and mammals such as caribou, foxes, bears, and small rodents. Which factor of the tundra ecosystem is biotic?

If the producer population in an ecosystem decreased, what would most likely happen to the size of the herbivore population?

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?

Which best relates cells and viruses?

Read this passage about global fishing.Global consumption of large fish has led to an exploitation of fish populations. Overfishing has led to a decline in the populations of many species of large fish including North East Arctic Cod. The graph below shows the decline in the cod population.As the human population grows and countries continue to develop, the demand for large fish has been steadily increasing. Unfortunately, the average size of the cod has decreased because the fishing nets were designed to catch the large fish and the smaller individuals could escape more easily.What is most likely happening to the genetic variation of the population of North East Arctic Cod?
