active role for the membrane. Osmosis and dialysis are also occasionally called passive transports because they too do not require an active role for the membrane. Osmosis is movement of water across a semipermeable membrane of low concentration to a solution of high concentration. On the other hand diffusion is movement of molecules from a high concentration to a low concentration. Osmosis is a form of diffusion but a distinction would be that it deals essentially with water. Tonicity is what makes the

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

scientific report will be based on cellular respiration‚ or fermentation. In specific‚ how the type of sugar affects the rate of fermentation. The aim of this experiment was to find which type of sugar was best suited to produce ethanol. In the experiment‚ four different sugars were used‚ they included sucrose‚ glucose‚ lactose and fructose. This research is still relevant today‚ as alcohol is still consumed and is required on a large scale. This makes it crucial to companies to find the best sugar to use

Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules
