Aim:To discover what factors affect the rate of diffusion of potassium permanganate crystals in water. Statement:What will happen? How will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystals?Hypothesis:Heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the potassium molecules.

Where as the active transport requires energy from the molecule to be moved. oFacilitated diffusion can only move in one direction from high concentration to low concentration‚ which is with the gradient. Where the active transport can move from both low concentrations to high concentrations‚ therefore it can move against the gradient where as the facilitated diffusion can not. The process of active transportation is when a molecule work together with the active side of a protein

Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

Discerning the Molecular Mechanisms of Entamoeba histolytica Erythrophagocytosis Abstract Entamoeba histolytica is a protozoan parasite representing a serious public health care crisis worldwide. It primarily affects people in low-income regions of impoverished nations and may affect the colon‚ liver‚ spleen‚ lungs‚ and brain. Erythrophagocytosis is a process that is vital to the pathogenicity of E. histolytica and therefore‚ the examination of molecular mechanisms involved

Weight training is a type of strength training that uses weights for resistance. Weight training provides a stress to the muscles that causes them to adapt and get stronger‚ similar to the way aerobic conditioning strengthens your heart. Weight training can be performed with free weights‚ such as barbells and dumbbells‚ or by using weight machines. Weight lifting is a crucial part of any athlete or active person‚ but studies show that weight lifting can be beneficial to the every day person‚ and

There are so many different methods to choose from. These choices range from extreme workout methods‚ such as the popular PX90‚ to interactive video games‚ such as the Nintendo WII fitness. Many people go to such extremes to lose weight that they cause more damage to their bodies. It is important to maintain

epidemic in many communities around the world‚ different weight loss surgery procedures and types have been introduced. Leading surgical facilities and clinics offer different procedures of bariatric surgery. Many of these procedures are performed using minimal invasive (laparoscopic) surgery. This helps to reduce the time a patient may need to stay in hospital. Furthermore‚ this also reduces the speed of recovery. The common types of weight loss surgical procedures include: · Malabsorptive procedures

Body weight is a hot topic in today’s society. Recent trends involving body weight include the protest against body shaming accompanied by the encouragement of the acceptance of bodies of all shapes and sizes. That being said‚ there is some cultural inconsistency that exists in the United States because although society ideally wants to accept people of all sizes and view them without judgement‚ many people allow a bias to cloud their views of people whose body weight is deviant from the norm. These
