capacity, mixed with 20ml. of carbon tetrachloride, 30ml of glacial acetic acid and finally 1ml. of saturated potassium iodide solution. After well shaken for 1minute, 100ml. of distilled water was added to and thus free iodine liberated in the solution was titrated by 0.01N thiosulphate solution. 1 ml. of this. thiosulphate solution corresponds to 0.00008g. of oxygen. The acid ester used here was prepared from cuttle fish oil as described…

My experience with Holz Lake was unique to say the least, from leaking waders to completely falling into the water it was all a very hands on activity. Coming to SES one of the things I was most excited for was the pond profile. All of the teachers said, “Don’t feel bad if you fall into the pond, it happens every year.” Hearing this, I knew I would likely be the student to fall into the pond.

Suddenly, a great shadow loomed…

able to survive and live comfortably in. Temperature was found to be a factor affecting the rate of oxygen consumption by altering dissolved oxygen levels. As stated by Powell et al. (2006), there shows to be less dissolved oxygen in warmer waters, and these waters have been found to increase rates of ectotherms that are in the respective conditions, because in order to survive they must acclimate to their environment (Daniels and Ermitage, 1968). According to this study, if the crayfish used…

did not clean every time. I predict that Mrs. Pearce closest table to her desk will collect the least amount of bacteria because they are less commonly used and clean sometime.

Euphonious sounds of laughter and boat engines running rings through the valley, bringing nothing but a colossal smile much too large for my…

Also, they protect the state from high winds by powering down the storm. Take for instance, some of the last few storms have caused an abundance of flooding due to the disappearance of the wetlands. Places that have never flooded become so full of water that many people evacuate. The wetlands of Louisiana are not just vital to the state of Louisiana, but also for the protection of the nation. Although the wetlands provide protection from storms,the wetlands provide a rich culture which…

The NaOH is a colorless solution. HCl is also a colorless solution. The test tube heated up immediately after adding in the (HCl). (3b) distilled water is a colorless liquid. While NH4Cl (Nh4 is known ammonium) is a white powder that looked like salt and also looked glittery. The test tube was cooled down. (4a) CuSO4 is an acura blur color solution that seemed to have stuff at the bottom of the bottle…
