Fish Schooling Abstract This experiment tested schooling behaviors between two species of fish. The fish used to conduct the experiment were Zebra Danio fish and minnows. The number of fish required for schooling and elapsed time was also accounted for. The results showed that mixed-species schooling may occur. The numerical quantity and time also proved to be a factor in the experimental results. Introduction A fish school is another word for a large unit of many fish which congregate

Lab 2 – Water Quality and Contamination Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell‚ Color‚ Etc.) Beaker Observations 1 Water is clear and uncontaminated. 2 All of the vegetable oil goes to the top of the beaker. 3 The water looks slightly cloudy but not too contaminated. 4 The water changed colors with the detergent and was clearly contaminated. 5 Water was murky from the dirt. 6 The water did not look as contaminated filtering with oil as it did with

Fish have been a protein source throughout history. Early fishing primarily involved individuals capturing fish near their communities for consumption or trade. Ships gave fishers access to ocean-based fisheries. Commercial fishing became industrialized by the late nineteenth century‚ as technological innovations helped locate‚ catch‚ and process fish. In addition to fish living in natural freshwater or saltwater fisheries‚ fish cultivated in fish farms ’ ponds or tanks represented approximately

America. Recent estimates of lionfish densities indicate that lionfish have surpassed some native species with the highest estimates reporting over 1‚000 lionfish per acre in some locations. Lionfish are capable of permanently impacting native reef fish communities across multiple trophic levels. Lionfish occupy the same trophic position as economically important species (e.g.‚ snapper and grouper) and may hamper stock rebuilding efforts and coral reef conservation measures.

UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each

Bottled Water vs. Tap Water In today’s society drinking water from a plastic bottle has become the norm‚ but just a few decades ago this action was not the case. During the late 70’s a French company named Perrier introduced bottled water to America and convinced people of the fact that drinking water from a bottle would make people look cool‚ so they advertised a new fashion of consuming this precious liquid. Companies like Coca-Cola and Pepsico saw the opportunity to start a division of bottled
