Biological adaptations have to do with our genetics and cultural adaptations are those made by physical objects such as housing‚ clothing‚ and tools. Biological adaptations are traits that get passed on to different generations through natural selection (Anemone‚ 2011). We can look at skin color as apart of biological adaptations and the absorption of UV rays and vitamin D. We get vitamin

    ethanol on the permeability of beetroot cell membranes. Prediction: By exposing a membrane to a solvent‚ ethanol‚ it will increase its permeability. So the higher the concentration of the solvent‚ the more permeable the membrane will be. But if the concentration of the ethanol is beyond a certain limit‚ it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol would disturb the lipids in the membrane. Therefore‚ more of the red pigment in the
