Describe the graph of flow versus viscosity. There was an exponential response, which was depicted on the graph. 4. Discuss the effect that polycythemia would have on viscosity and on blood flow. Polycythemia is an increase in red blood cells, which would increase the viscosity and decrease flow.
Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain. There may be oxygen poor zones in the ocean, coral extinction, and a decline in photoplankton (Skeptical Science, 2012). Our natural water springs may fail causing people in different areas of the globe to live without drinking water. There could be more wildfires, droughts that cause a loss of vegetation, and heat deaths or floods and storms (Enzler, 2007). The migration pattern of birds and other animals will change, there will be a disruption in our foodchain on land, and the possibility of loosing some species.
The Colorado Compact was created in 1922 to establish rights between states. However the period of time in which the agreements were made was during a time of greater rainfall and water surplus. Present environmental conditions and human activity has lead to a decrease in available water which is causing conflict between a wide range of stakeholders in many regions of America – especially Mexico, and lower basin states such as California. One group of stakeholders already suffering are farmers. Agriculture receives 80% of the Colorado River supply, and much of this is wasted in inappropriate crop choices, e.g.
Thermal runaway reaction- What is a thermal runaway reaction? Thermal runaway reactions happen when heat generation increases with the increase in temperature and may occur due to many factors, including lack of process control or lack of cooling. The rise in pressure can happen because due to vaporisation of some of the components of in reaction mass.  What causes thermal runaway reactions? Thermal runaway reaction occurs when the heat generated by a reaction goes beyond the heat removal caused by the available cooling capacity.
Oceans play a vital role when it comes to climate regulation, but there has been an escalating change in the sea temperature over the last few decades which contributed to sea levels rising. Oceans act as carbon dioxide main stores and a proportion of the carbon uptakes are exported along the ocean carbon pumps. An increase in the sea’s temperature and ocean currents may lead to a decrease in the uptake of Carbon dioxide by oceans. The ocean chemistry has already been affected as we are facing ocean acidification- which impacts species such as corals and calcareous plankton, aquatic and land ecosystems and the biogeochemical cycles. 1.10) What is the effect of climate change on biodiversity in the oceans and on land?
The inability of rain will led to increase heat and that may lead to have dryer soils and that would have a big impact in our agriculture. Productivity will decline. Even though if that happens irrigation to fill water needs could be a way to help the need of rain. The soil of Indiana is a major natural resource that temperature changes will affect, hotter drier summers, would be the main cause of loss soil organic matter and will result an increased soil respiration. Loss of soil will decrease the ability to retain moisture and specially essential nutrients for plant growth.
First, if the government increases its purchases but keeps taxes constant, it increases demand directly. Second, if the government cuts taxes or increases transfer payments, households’ disposable income rises, and they will spend more on consumption. This rise in consumption will in turn raise aggregate demand” (Weil, 2008, para. 4). Consumer income has a huge effect on aggregate supply and demand just as the aggregate supply and demand can affect consumer income.
Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
