    The three different levels of temperature that we will test are: 4*C‚ 25*C‚ and 85*C. To determine if lactase reacted on the different levels of temperature we will use glucose test strips. Table 2. Lactase functioning affected by temperature level Our results on Table 2 reflect that for the test tube that was placed at a temperature of 85*C had a negative result‚ meaning that no glucose was found. The test tube that was placed under the 25*C level of temperature contained the

    In this practical an electroencephalogram was carried out. An electroencephalogram (EEG) is a test that measures the brain waves and electrical activity of the brain by way of field potentials. It is used in both awake and asleep states. The human brain allows functions of various mechanisms to occur by communication within the brain. The communication within the brain is done through neurons of various sorts‚ sending action potentials through various regions. Each region in the brain will have specific
