Concentration

Abe and i met at the concentration camp. This happen whenever we were looking for our shoes, we were both trying to hurry up before someone steals them. We had to make a perfectly bed in a military manner. Which was impossible. Abe had her bed right next to mine, when i met her i felt a reason to stay strong she was my best friend and the only person I trusted. There were hundred of other prisoners there too. We were always starving the only thing the Kopo gave us was 10 ounces of bread and…

membrane. This process is called diffusion. In diffusion, particles move in motion at a random speed from a high concentration to an area of low concentration until all of the molecules are dispersed evenly. It is important to remember that involvement with diffusion depends on the concentration. The greater the concentration, the greater the rate of diffusion. Also known as the concentration gradient. Another process in which particles enter and leave cells is osmosis which is a kind of…

interesting, high concentrations of zinc stimulated the growth better than low concentrations (Table 37), Aluminum could stimulate the growth of the fungus slightly in concentrations 100 ppm and 300 ppm respectively. Lower and higher concentrations slightly inhibited the growth but aluminum couldn’t stop the growth of the fungus (Table 37, Fig. 46). While (Mn , Cu and Pb) succeeded to stimulate the growth of Mucor hiemalis up to 100 ppm with variable extent of growth, but higher concentration…

was given a phosphate reduced Hoagland’s solution, whereas Pot B (nitrogen limitation group) was watered with nitrate reduced Hoagland’s solution. Pot C (control) is the control plant as it was given standardized fertilizer regime using normal concentration nitrates and phosphates. All plants were grown in a growth chamber at a temperature of 22°C, the light intensity of 180 ue, photoperiod of 16 hours and humidity of 70%. After 4 weeks, one leaf from each treatment was collected and…

I examined the effects of buffered and unbuffered gibberellic acid on Daphnia magna and Daphnia pulex. I used six different concentrations: 0 mg/L (control), 1 mg/L, 5 mg/L, 25 mg/L, 125 mg/L, and 625 mg/L. Gibberellic acid (99% purity, Chemservice, West Chester, PA) was dissolved in deionized water as it ionized into gibberellin and H+ ions. Buffered and unbuffered gibberellic acid…

uction The point of this experiment is to examine the result of altering the concentration of sucrose on the rate of osmosis in cylinders of potatoes. This would occur by using like sizes and lengths of potato cylinders and applying them into varying concentrations of sucrose (1%, 5%, 10%, 15%, and 30%) in test tubes then assessing the change in mass of the potato cylinders after. Sustaining all variables unaffected such as the pH, same size, and a constant temperature. Hypothesis: I predict if…

A dilution is created when two solution are mixed together to reduce the concentration, or when water is added to a solution for the same reason. Molarity is the amount of molecules that a substance contains, for example, the amount of sodium ions in water after adding 2 grams of salt or the amount of sodium chloride molecules to in 10 grams of salt. The reason that we need to understand the molarity of a substance is to have a more controlled experiment. When the molarity of a substance is…

passive transport. Think about molecules and ions move in motion in a solution. When a random motion cause a net movement of a substance of high concentration to low concentration is called diffusion. That is where the molecules spread out evenly throughout the area. When you have a difference in the concentration in a distance is called a concentration gradient. Random movement of molecules are called Thermal Molecular Motion. There are two factors that can effect the speed of a thermal…

The rheology characteristics of enzyme clarified beetroot juice with added additives such as maltodextrin (MD), inulin (INU) and their combination (MD+INU) was studied at a wide range of concentrations (0 to 20% dry solids) and temperatures (5 to 80°C) by controlled stress rheometer. The rheological parameter shear stress was measured upto the shear rate of 600s-1. The temperature dependency of Newtonian viscosity of beetroot juice was described by Arrhenius equation. The effect of added solid…

sensitivity was found to be 44.7 ppm/Abs units. This means that in one increment of absorbance, the concentration is 44.7 ppm or for 0.01 increment of absorbance, the concentration increases by 0.447 ppm. This shows a low sensitivity for the thiocyanate system. The detection limit was also calculated, which was found to be 0.4038 ppm. This correlates with the earlier attempts in analyzing solutions with concentrations less than 1 ppm. While inaccurate due to the rapid conversion of the complex,…
