The aim of this experiment was to show the water potentials of young‚ old and damaged potatoes and different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn

Computer Simulation of Cell Transport Mechanisms and Permeability: Passive Processes and Active Processes Introduction In this lab we will establish a difference between the two types of cell transport mechanisms and their permeability. The first type of cell transport is passive processes which are driven by concentration or pressure differences in the interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two

3/22/2013 Lab 1- The scientific method In this lab I am learning about the steps of the scientific method and how it can be applied to daily life. In my first exercise I analyzed data presented to me in a table (table 2) on fish population in relation to the amount of dissolved oxygen ( ppm ) in the water. The patterns indicate that when more dissolved oxygen (ppm) is present in the water‚ the number of fish observed increases. In developing a hypothesis for this theory‚ I have decided that if

we say the electric field is spherically symmetric. The magnitude of the field decreases more quickly than the inverse of the distance from the charge. The magnitude of the electric field is proportional to the inverse of the distance squared (E∝1/r2‚ where r is the distance from the charge). You should verify this by looking at the field

Part 1 Part 1 of the experiment investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower
