Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around

Since they had crops‚ they could use domestic animals to work for them. This led to the immunity to smallpox from being in close quarters with the animals. Europeans also had

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

However‚ the 35oC temperature had a no clear skew of results as indicated through the range‚ 14 and the error percentage‚ 161.47%‚ suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies‚ however‚ not as significant as the previous temperature‚
