1: Correct Use of the Scientific Method and an Experiment with Macromolecules I. Objectives In this lab‚ students will: a.) Learn how to utilize the Scientific Method to develop a testable hypothesis b.) Generate an effective experimental design from a hypothesis c.) Understand the chemical differences between different macromolecules and how these differences can be used to design tests for each molecule. d.) Identify macromolecules in solutions using chemical analyses. e.) Practice recording

Zebrafish Embryotoxicity Test (ZET) The ZET will be done following the method proposed by Beekhuijzen et al. (2015) with modifications. Six embryos will be exposed to each of the following treatments: 0.1‚ 0.05‚ 0.025‚ 0.0125‚ and 0.00625 mg/ml. Embryos will be incubated in 24-well plates with built-in lids. Each well will contain one embryo and 2 ml of the respective treatment. All test solutions will be renewed every 24h to maintain the integrity of the test concentrations. The embryos will

As a result of the tests ran‚ I was able to identify the unknown bacteria. For Unknown A‚ I ran six tests. I first isolated the bacterium from the second bacterium and found a clear growth (Table 1‚ Figure 1). Secondly‚ I ran a gram stain and found a gram positive‚ cocci bacterium (Table 1‚ Figure 2). Third‚ I ran a catalase test in which was negative (Table 1). From here‚ I determined a starch hydrolysis test would be necessary to distinguish between different bacteria. The result was negative (Table

Cold pressor test is widely used as test for auto- nomic functions. It has been used as diagnostic test for diseases like hypertension and other cardiac auto- nomic disorders. During cold pressor test ‚ the hand or foot is immersed in cold water bath held at a con- stant temperature at 80 C. Cold water immersion activates afferent pain and temperature neurons‚ re- sulting in a centrally mediated stimulation of sympa- thetic efferent neurons. In healthy subjects ‚ the CPT causes increase

1. Both of the subjects in this test preformed excellent compared to the rankings provided. Victors Mean Power put him in between the 85 to 90 percentile with his score of 639.83 and his Anaerobic Capacity put him in between the 60 to 65 percentile. These scores indicate that Victor trains more with resistance than aerobic type exercises because of the high score of his Mean Power. These scores also correlate with his VO2 Max test we preformed earlier. His VO2 Max of 3.4 is low compared to the high

4 gram stains‚ the slide was blot dried and observed under microscope at 100x with oil immersion. The slide either appear in pink (gram-negative) or purple (gram-positive). Catalase Test: Catalase test enzyme detection of microorganisms‚ catalase hydrolysis hydrogen peroxide (H2O2) into H2O and O2. The catalase test was performed by used a sterile transfer loop been flamed to remove small amount of bacteria from slant agar and placed on the slide. Then

Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving
