LS 1 LAB DEMO 1 13 January 2014 Introduction: The broader context of this lab was aimed at observing animals and documenting specific animal behavior patterns. Specifically‚ we were trying to determine if squirrels applied snakeskin randomly to certain areas of their body or if there was a specific technique to it in relation to escaping their predators. After an animal has determined that a predator is nearby‚ it must then take action to avoid encountering this threat. Encounters are most easily

Interreach variability and correlation analyses between biotic and abiotic factors of the Old Chelsea stream BIO2129 Section Demonstrators: October 1‚ 2014 Department of Biology Hypotheses Water quality parameters such as pH‚ dissolved oxygen‚ seston‚ water temperature etc. are important variables in the abundance and diversity of benthic macroinvertebrates of the Old Chelsea stream. Therefore‚ it can be hypothesized that pH and dissolved oxygen have a direct correlation on biotic factors

Water molecules form hydrogen bonds between them. This produces a surface tension which makes it hard for a small object to break the surface. e. Universal Solvent iii. The polarity of water molecules allows both organic and inorganic particles to dissolve in it

Whitney Shepard BIOL9999 1/26/2015 Microbes in the Environment Abstract Microorganisms are plentiful and widespread in the environment. In this lab‚ we undertook to determine the differences in the agars being used and the different colony count observed. After taking four different samples of microbes from the environment and swabbed them in two different plates one with nutrient agar and the other with sabouaud dextrose agar. After the microbes had incubated for 48 hours no results were discovered
