Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide. In the body

temperatures to the enzymes in the higher temperature we observed that the enzymes were functioning at a significantly reduced rate at the 24ᵒC temperature and was completely inactive at the 0ᵒC temperature. Whereas when we compare to the higher temperatures (60ᵒC) the enzymes should have functioned with reduced efficiency and should have even denatured which would

Chapter 12 2. What is consumption smoothing? How does insurance help people smooth consumption? When consumption goes from a period of high consumption to a period of low consumption. For example‚ if a person does not save money at all while they work in order to live a high maintenance lifestyle then they suddenly get laid off‚ they must greatly reduce their consumption because they can no longer support their lifestyle. Insurance helps people smooth consumption because it helps them defend against

Enzymes lower the amount of energy needed in a chemical reaction. This happens because enzymes are catalysts‚ so they speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has

Learning From Others By: Me! There is something I have observed as I have grown‚ and that is‚ if we value our own lives and generations after us‚ we must learn from others to better our future. There are many things from which we can learn throughout our lives. In particular‚ we can learn from the past‚ present‚ and our future generations. In the past we have had many horrific tragedies including the Holocaust which occurred during World War II in 1945‚ and the bombing of Hiroshima in

How might pricing decisions be influenced by knowledge of the Product Life Cycle? Product Life Cycle (PLC) shows the stages of a new product going through in the market place. In general‚ a product goes through introduction‚ growth‚ maturity and decline. The application of the four stages of PLC can assist firms to plan marketing mix decisions. Hence‚ price setting of a particular product can be influenced by its PLC over the four stages. For mass market with high competition and a new brand

1.a. Increase pressure from the thoracic cavity onto the venae cavae causes the stroke volume to decreases‚ cardiac output would decrease‚ venous blood pressure would eventually increase and venous return would also eventually increase. b. Fainting is due to a drop in blood flow to the brain. And holding your breath causes the heart rate to slow and blood vessels to dilate‚ which then leads to blood pools in the lower body and less blood going up to the brain. c. Compensatory mechanism that become

How Cancer Cells Differ From Normal‚ Healthy Cells Cancer cells are very different from healthy cells. Healthy cells grow and divide like they are suppose to‚ whereas cancer cells do not grow and divide in a healthy way. So instead of acting in healthy ways as the body needs to function the cells begin to grow in unhealthy ways and affect all other cells. (http://biology.about.com/od/cellbiology/ss/normal-cells-cancer-cells.htm) There are many things that can happen to us that can cause our healthy

reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher from Greece suggested that matter is made up of tiny particles too small to be seen. He thought that if you kept cutting a substance into smaller and smaller pieces‚ you would eventually come to the smallest possible particles. The rate of a chemical reaction
