exercise on heart rate/ breathing rate? Justification Pulse is an ongoing wave of pressure in the arteries‚ caused by pumping of heart. Pulse can be measured on the wrist‚ neck‚ back of the knee or any other pulse point where arteries run close to the surface of the skin and compress on the bone. Pulse rates vary from person to person. Your pulse is lower when you rest and increases when you exercise. More oxygen rich blood is needed by the body when exercising so knowing how to take your pulse

differently‚ specifically a person’s heart rate and blood pressure. After exercising your heart rate should increase and your blood pressure should decrease (Blood Pressure Association‚ 2008). The purpose of this lab was to determine which level of exercise would have the greatest impact on affected pulse and blood pressure. In this lab we tested how exercise affected heart rate by testing a random group of people with different body types and exercise levels to see how different types of exercise would affect

ECONOMIC VIEWPOINT: DOES ABORTION LOWER CRIME RATE? By: Robert J. Barro This article reviews various reasons for lower crime rates in the United States since 1991. There were many explanations offered such as better cops‚ strong economy‚ restrictions on crack cocaine. Of all the explanations offered‚ legalizing abortions was very interesting and unpredictable among them. It clearly had the evidence that legalization led to increase in number of abortions in 1973 resulting in drop of crimes in 1991

Biology Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first.

With close reference to pages 183-186 analyse Salinger’s use of language and structure‚ exploring Holden’s contradictory view of the world. On Page 183 Holden says ‘you could tell the two hot- shots I was with weren’t enjoying it too much. They stayed close as hell to me‚ and the one that didn’t talk at all practically was holding onto my sleeve’. Holden calls them ‘hot shots’ because they acted phony by bunking school and then lying about there being no school. (P182). Throughout the novel‚ Holden

temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient energy for the substrates to move at a fast rate‚ hence decreased the number of collisions with the enzymes. However

How does Stevenson use the concept of duality in his Jekyll and Hyde novella? In my essay I will conduct a detailed analysis‚ on how he displays a concept of duality that Dr.jeykll and Mr.Hyde battle in a conflict of good and evil in the vast double psychological character‚ also how the suspense will attract the reader with mindboggling suspense. This key element is vital in keeping the reader hocked to the novella. Robert Louis Stevenson incorporated the ideology of duality in the book as a main
