Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

have different demands in the current industry. The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on how does the carbon chain length of carboxylic acid and alcohol affects the rate constant and equilibrium constant of esterification. Thus‚

Lights‚ Camera‚ Action. Light it up. As the popular Soca song goes‚ ‘Let me see you light up the Air’. Or Vybz Kartel’s song says ‘Light the Weed’. All focused around the presence of light. We cannot see without light‚ so in this regard‚ light illuminates our path. For this reason we ensure that our surroundings are fitted with lightbulbs. We cannot function in school or work or in life if there isn’t some measure of light. I’m here to enlighten you about the choice that you will face when purchasing

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the

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
