The Pressures of Guilt Everyone sins. It is an inescapable fact. The magnitude of guilt for these sins‚ however‚ depends upon the creed‚ religion‚ or ideals of the sinner. In both The Crucible‚ by Arthur Miller‚ and The Scarlet Letter‚ by Nathaniel Hawthorne‚ readers see the effect of the Puritan faith on guilt. Strong‚ as well as weak‚ characters face guilt in each book. Abigail and Dimmesdale take a coward’s way out‚ while Hester and Proctor wrestle with their guilt. By upholding the strictures

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2

observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton muscle carries our anaerobic respiration to provide addition amount of

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However‚ in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration‚ we need to understand what

BLOOD PRESSURE When your heart pulsates‚ it pushes blood in your body to give it the vitality and oxygen it needs. As the blood moves‚ it pushes against the sides of the veins. The amount of this pushing is your circulatory strain. On the off chance that your circulatory strain is too high‚ it puts additional strain on your arteries (and your heart) and this may prompt to heart attack and strokes. The force that makes weight on veins that is your systolic blood pressure. An ordinary systolic pressure

I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then
