The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

Aim: To investigate the effect of skin sensitivity in response to cold temperature in different parts of the body by timing the maximum amount of time in which ice-pack can be held to that area. Hypothesis: If the layer of skin is relatively thin‚ the nerve response to cold will be the fastest‚ increasing the skin’s sensitivity. This therefore means that the fastest responses to cold will be in the face‚ and specifically the nose. The skin consists of 3 main layers; the epidermis‚ dermis and

Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces
