Salinity is the measure and concentration of all the salts dissolved in water. Usually measured in parts per thousand (ppt or )‚ ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less (University of Rhode Island). Many factors go into salinity‚ making water salty. To name a few‚ salinity affects the environment through sediment from rocks washes into the ocean‚ evaporation of ocean water‚ and sea ice formation are known to increase the salinity of the ocean (NASA).

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Science of Biology Mrs. Farrow Lab 3 – Slime Time Submitted by Chase Kenemer 22 February 2015 Abstract Polar solvents dissolve‚ or pick-up‚ polar substances and non-polar solvents dissolve‚ or pick-up‚ non-polar substances. In the conducted experiment‚ the polarity of molecules and their properties are explored. The results of using two solvents on both polar and non-polar inks‚ further verify this to be true. The student conducted the experiment given‚ using safe lab practices‚ that found the

The ANOVA Table Printer-friendly version For the sake of concreteness here‚ let’s recall one of the analysis of variance tables from the previous page: In working to digest what is all contained in an ANOVA table‚ let’s start with the column headings: (1) Source means "the source of the variation in the data." As we’ll soon see‚ the possible choices for a one-factor study‚ such as the learning study‚ are Factor‚ Error‚ andTotal. The factor is the characteristic that defines the populations

must you use lead pencil‚ instead of a pen‚ to mark your chromatography paper? A lead pencil should be used instead of a pen because the ink of the pen would dissolve in the eluting solution and separate. The components of the ink could mix with the other ink/ dyes that would be tested on the same chromatogram. Thus‚ a lead pencil should be used. 2. Why should you avoid touching the surface of the paper to be used for amino-acid chromatography? We should avoid touching the surface of the chromatogram

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One
