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.
Today, climate change is being driven by the addition of carbon dioxide and other greenhouse gases to the earth's atmosphere at rates faster than the planet's normal mechanisms can adjust to. The result is increasing concentrations of these gases in the atmosphere, and because they trap heat, increasing temperatures. This hurts people, animals, and plants. How do we know this? Scientists predict that if the increase in greenhouse gas emissions continues unabated, temperatures will rise by as much as 10 degrees Fahrenheit by the end of this century, potentially causing dramatic and irreversible changes to the climate.
(b) Mean temperatures are rising in many parts of the world. The rising temperatures may result in physiological and ecological effects on living organisms. Describe and explain these effects. Topic areas for assessment of scientific content: (1) principle of destabilising effect of rising temperature on metabolic systems within organisms and on balance in ecosystems. (P) (2) effect on rate of diffusion/gaseous exchange; possible consequences, e.g.
The force of the isometric contraction increased as the muscle load increased. 9. Which would be a better predictor of increase in force of contraction, change in sEMG amplitude of spikes or change in sEMG frequency of spikes? Change in sEMG frequency of spikes. Discussion 1.
This extreme pressure change makes the iso bars compact together creating fast moving winds and causing wind speeds to increase to even out the air pressure. 3. Describe the changes in central pressure and sustained wind speed between 29 and 30 August 2005? The air pressure from august 29th to august 30th changed from 904mbars to 985 mbars. While the air pressure increased the winds decrease as iso bars spread apart and wind is no longer moving at an abrupt pace.
Less rainfall means there is less water to enter into the facility and transport radioactive waste. On the negative side there are three things which cause me an unsteady feeling. First, the mountain is in an area where there has been volcanic activity. Because of the activity strong gases have entered into the ground which could cause explosions to be destructive. Secondly, the area has several faults running through the area where the proposed facility was to be built.
Expansion, an increase in the volume of a substance, usually due to the addition of heat to the substance. The heat causes the molecules of the substance to move farther apart, making the substance occupy more space. A loss of heat causes the opposite effect, known as contraction. Although most substances expand when heated, not all expand at the same rate. Aluminum, for example, expands twice as much as iron when both are heated the same amount.
To what extent does the world have an energy crisis? There has been an enormous increase in the global demand for energy in recent years due to rapid industrial development and population growth, especially in the less developed countries. The crisis will become when demand exceeds supply. A crisis like this can develop as a result of industrial actions such as strikes and government refusal for the movement of merchant ships in or out of ports. The cause of these could be over-consumption or prices rising at oil refineries.
Acid rain as a result of industrialization has had many negative effects on the New England region in particular. The Adirondack Mountains are of special interest due to their soil composition that does not allow for the seizure of the two primary particles in acid rain. This has caused issues pertaining to the water reservoirs in the area that now are sometimes unable to support life do to the high acidity. Acid deposition as it is more formally called is typically composed of sulfur dioxide and nitrogen oxide. These two components are naturally occurring from sources like volcanoes but the industrial revolution has exponentially increased the amount of these chemicals in the air.
The purpose of the experiment is to determine whether or not increasing temperature will increase the rate of the reaction. Reaction rate is a way of measuring how fast the reaction takes place. So the higher the reaction rate the faster the reaction takes place and the lower is the reaction time is. Research Question How does reaction rate change with increasing temperature of sodium thiosulphate in a reaction between hydrochloric acid (HCl(l)) and sodium thiosulphate (Na2S2O3(l)) ? Hypothesis With increasing temperature of sodium thiosulphate the reaction rate will increase as well.
