franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

tank and a flow visualization pipe. The header tank is provided with a diffuser and stilling materials at the bottom to provide a constant head of water to be discharged through a bellmouth entry to the flow visualisation pipe. Flow through this pipe is regulated using a control valve at the discharge end. The water flow rate through the pipe can be measured using the volumetric tank (or measuring cylinder) of a Hydraulics Bench. Velocity of the water can therefore be determined to allow for the calculation

cations presented to the student. But in order to know the identity of these unknowns‚ in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate. Starting out the experiment‚ HCl was added

The cotton has to be loose enough so that air can pass through‚ but tight enough that the mealworms cannot pass through. Put another small piece of cotton behind the second piece and leave about 2cm in between it and another piece

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

The purpose of this lab was to observe osmosis in the Gummy Bears and to investigate the movement of water in and out of a Gummy Bear. The hypothesis stated that the salt will make the gummy bear weigh more‚ but it will keep the gummy bear more intact. However‚ the results showed that the gummy bear decreased in mass because of the salt and water. This contradicts the hypothesis because of how it was believed that the gummy bear would increase in weight‚ but it did the exact opposite. One part of

Pixar Facts 1.) In order to give Dash a realistic out-of-breath voice in "The Incredibles‚" director Brad Bird made actor Spencer Fox run laps around the studio.4 2.) Every Friday during the production of “Brave‚” each Pixar employee was told to wear a kilt for the fun of it. 3.) Shortly after completing Toy Story‚ the Pixar chief creative staff of John Lasseter‚ Peter Docter‚ Joe Ranft and Andrew Stanton got together for a lunch meeting at the Hidden City Café in 1994 that would become one of

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other
