Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

amount of pressure‚ intensity and type of exercise. When performing a cardiovascular exercise‚ the blood becomes directed to the muscles that are physically conducting the exercise. As well as when the blood volume and flow return to the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This increases the heart rate because the movement

Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

Sometimes the data we need may not be available from internal or external sources. In such cases‚ we may have to obtain data by conducting our own survey or experiment. In a survey‚ we do not exercise any control over the factors when we collect information. For example‚ if we want to collect data on the money various families spent last month on clothes‚ we will ask each of the families included in the survey how much it spent last month on clothes. Then we will record this information. A survey

Isaac Newton (~1665) made up a particle model of light to explain many of the known behaviours of light at that time

Photosynthesis is the process which plants use to change Carbon Dioxide and water into sugar by using the sunlight. Photosynthesis usually take place in plants cell such as chloroplast. In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many

I used to believe that love was a light switch. Something flicks on. You get an overwhelming sensation. It hits you like a bag of bricks. Or a strong arrow. When you know‚ you know. Right? Not so much. After 28 years‚ I don’t see love that way anymore. I’ve placed Cupid right next to Santa Claus and the Easter Bunny. Love is a series of choices. The first choice is based on many many factors‚ including chemistry‚ principle‚ logic‚ humor‚ intelligence‚ body type‚ where we are in our lives‚ what

However‚ as the amount of air decreased‚ so did the rate at which the balloon moved. If the string was not held tightly‚ the balloon bounced around quite a bit and did not travel as far. In this lab‚ I was examining the amount of power and work that was done by the balloon as it travelled. But was the balloon

High intensity interval training (HIIT) is a new popular method of exercising that optimizes your workout by completing a series of short‚ high intensity exercise (90% of your maximum heart rate =220-age).‚ followed by longer‚ lower-intensity exercise (55 to 70 % of your maximum heart rate=220-age). High intensity interval training is said to be significantly more beneficial than other forms of cardiovascular workouts because it challenges the body differently and is more extreme then a moderate
