Acid Presipitation

Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone that is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren’t absorbed into the clouds, they can drift for miles and fall […]

Investigating Membrane Permeability

Investigating Membrane Permeability Reason for choosing beetroot as the object of experiments Beetroot is usually used as the membrane ‘disruption’ experiment. It is because of beetroot has more pigments in their vacuole. These pigments show how variables damage the membrane of beetroot. The pigments will be automatically extracted from the vacuole when the membrane is […]
