The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

Emily K 20 August 2013 Diffusion Lab Research Question: How does the amount of water in a beaker affect the rate at which food coloring diffuses to the bottom of the beaker? Independent Variable: Height of water in beaker (Inches) Dependent Variable: Rate of diffusion (seconds) Controlled Variables: * Size of beaker * Temperature of water (23°C) * Type/color of food coloring * Person Timing * Environmental conditions Materials: * Beaker(well over 4 in tall) * Food

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.

solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to leak out by diffusion. Biological principle:

Alisha Prakash Biol 111-513 The Properties of Water; Osmosis and Diffusion Hypothesis: When animal and plant cells are placed in a solution‚ the movement of water is effected by the solute concentration of the solution. If animal and plant cells are placed in a more concentrated solution‚ the solution becomes hypertonic to the cells‚ causing water to exit the cells. This changes the appearance of the cells‚ causing the cells to look darker (more concentrated) and shriveled up. Null Hypothesis:

True happiness and artificial happiness are two similar‚ but very distinct emotions. The society in which one lives and the surroundings draw a fine line between the two. Happiness is pleasurable satisfaction which results from the possession or attainment of what one considers good‚ while artificial happiness can be defined as a state of happiness because it is the effect of relying on a substance to make one happy‚ therefore making it artificial since it does not come naturally. Happiness is not

Philosophy Assignment Three Proving Artificial Intelligence For many years one of the greatest debates between many notable philosophers has been the nature of Artificial Intelligence. Much of this debate has been centered around whether or not this Artificial Intelligence is capable of concious thought or that it simply just appears to think and is not actually conscious in the same way as is a human brain. In this paper I will take into acount the views of William Lycan‚ John Searle

If there isn’t any artificial gravity present then the human body is extremely stunned which forces all the biological functions to break down. Astronauts that are in orbit for a long period of time tend to show major decreases in their bone strength‚ muscular tone‚ and also
