    Hypotheses and Predictions: The authors wanted to test if it is possible to detect increased metabolic work in two estuarine species (Hemigrapsus oregonensis and H. nudus) and relate this function to increased osmotic work by measuring oxygen consumption with respect to changes in temperature‚ salinity‚ and the gradient‚ which they defined as the difference in concentration between blood and the external medium. The authors predicted “because of seasonal variation in salinity it would appear quite

    1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the
