Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Darwin and Wallace Island Finch Evolution Lab Experiment BIO/101 Darwin and Wallace Island Finch Evolution Lab Experiment Evolution and Natural Selection have been a recurring focus of biology throughout the years. This Particular experiment is based on Charles Darwin’s observations of finches made in the Galapagos Islands. He noted that different neighboring islands in the Galapagos had distinctly different types of finches. He theorized that this was caused by natural
