NOTES FROM MR.ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute

ent chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved. Two drops of a chemical were placed in a well along with two drops of another chemical. Chemical reactions and color changes were recorded in Data Table 1. Observations During the experiments a few problems were encountered. One of the chemicals provided differed

Hand Sensitivity Are people more sensitive to cold water on their dominant hand or non-dominant hand? If a person sticks their hand in cold water‚ then their dominant hand will be able to withstand cold the longest. To conduct the experiment two bowls of the same size were filled: one with room temperature water and one with cold water (adding lots of ice). After this was done‚ each participant put both hands in each bowl (one at a time). The time was recorded how long each participants had each

ISC Board Important Questions Biology [Set-1] Q1. a) (i). Absorption spectrum and Action spectrum Answer: A curve obtained by plotting the amount of absorption of different wavelengths of light by a particular pigment is called absorption spectrum of that pigment. An action spectrum is a curve showing the effectiveness of different wavelengths of light in stimulating the process being investigated. (ii).
