molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the particle. For example‚ a smaller particle will move faster than a large molecule at a given temperature . During reactions‚ when there is more energy‚ the reaction will take place

one must obtain a social security number. In the case of the illegal immigrant‚ this social security number must be a forgery. The time and effort to obtain such a fraudulent number is often enough to deter immigrants from paying taxes‚ regardless of how much want to contribute to the society that has been their salvation.

Introduction Water is known as a vital component to sustain life. When one is confronted with the fact that water is considered a renewable resource in the short term but only 3% is usable (N.Gray)‚ precautions must be taken to ensure the conservation of water. The agriculture industry consumes approximately 70% of the planet’s usable water globally. At large scale the water footprint arguably cannot be reduced‚ raising the question on whether our water is being used to its full potential. Water

on the bone. Pulse rates vary from person to person. Your pulse is lower when you rest and increases when you exercise. More oxygen rich blood is needed by the body when exercising so knowing how to take your pulse can help you evaluate your exercise programme. The amount of exercise someone does will affect the pulse rate. For example‚ more exercise means more movement so more energy will be needed. In order to get more energy‚ respiration takes place at a faster rate. More oxygen is used so more

Data Analysis Does radiation affect the growth of seeds? If‚ plant seeds are exposed to microwave radiation‚ then the seeds will grow less than how a seed is usually grown. The independent variable was the amount of microwave radiation the seeds receive. The dependent variable was the growth of the plant seeds. Control variables were the amount of water (30 mL at a time)‚ the amount of light (11 hours each day)‚ and the amount of seeds. The control group was the non-microwaved seeds. The experimental

Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat
