How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

Did you know that many horror stories use cause-and-effect to create suspense? IN “The Tell-Tale Heart” and “The Monkey’s Paw” they both use cause-and-effect to help keep you on your seat. The cause-and-effect helps build suspense because you don’t know what will happen because of their one choice. “The Monkey’s paw” is a suspenseful story full of karma‚ when one thing would take place another one was set in order because of their decision. When their old friend came back from India he had a story

Heart rate is an extremely important part of many people’s lives. It affects our personal health and how our body works. When the body exercises‚ the heart rate goes up and when the body is inactive or not being active the heart rate goes down. When the pulse is pumping fast‚ then that means work is being done. Having a high heart rate is good for the heart and the body. Obese people can use heart rate and exercise to change their life. Due to the amount of people that are obese‚ a good amount of

start of the experiment‚ there was a total of 2.25g of caffeine (the net weight of the tea bag). After preparing the tea solution‚ extracting‚ drying and evaporating the weight of crude caffeine was .0321g‚ making the percent recovery before sublimation 1.43%. After sublimation the weight of pure caffeine was .0027g‚ making the percent recovery of caffeine after sublimation .12%. The percent recovery of caffeine is less in the second half of the experiment because the crude caffeine had some impurities

lips. Similar to a drug habit‚ the more a person drinks coffee‚ the more it seems like that person can’t function without it. But what are you really getting from your coffee? Along with other factors‚ coffee can have both positive and negative effects on your health. Coffee improves the body’s tolerance to glucose by increasing metabolism or improving its tolerance to insulin. People who drink four cups of caffeinated coffee each day had shown to be 56 percent less likely to develop diabetes

Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because

Compensatory mechanism that become activated include; increase sympathetic outflow leading to arteriolar vasoconstriction‚ venoconstriction‚ and increase in heart rate; d. Increase pressure in the aortic arch will activate the aortic arch reflex and cause increased parasympathetic stimulation of the heart.

Moderate drinking can have beneficial effects on the heart‚ especially among those at greatest risk for heart attacks‚ such as men over the age of forty-five and women after menopause. But long-term heavy drinking increases the risk for high blood pressure‚ heart disease‚ and some kinds of stroke. According to findings published Jan. 29 in the journal Stroke. People who average more than two drinks a day have a thirty-nine percent higher risk of stroke compared to those whose daily average amounts
