Daniel Bergey Lab 2: Proteins and Starches Purpose The purpose of lab 2 and both tests with proteins and starches is to determine which substance contains either protein or starch. Hypothesis Proteins: I predict that any substance I test that derives from a living organism is will test positive proteins. Any substance that isn’t from a living organism more than likely will test negative for proteins. Starches: I predict that any substance that contains any level of glucose will test positive

purpose of this lab was to study the specific characteristics of cations and anions‚ and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. A logic tree is a graphical display of the findings from this lab which‚ through a series of yes/no questions‚ elimination tests‚ will help us to identify and unknown sample. This lab will result in 2 logic trees‚ one for identifying cations and the other

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

In this lab 8 total substances were tested to find out whether they are a Protein or a Starch. It is my belief that only 1 or two of each of the substances in test 1( proteins) and test 2 (starch) will test positive for either protein or starch. For this lab the following materials were needed to complete the experiments in test 1 for proteins: Di water‚ ev milk‚ 50% egg solution‚ 1% sucrose‚ 4 test tubes‚ 1 test tube rate‚ safety glasses‚ pipets and the reagent solution. For test 2 for starches

Lab 2.1 Exercise 2.1.1 All these elements are necessary because each allows the other to function and do its job. Without Media the signal cannot transmit. Without Interface the computer cannot access the Media. Without the signal the electricity or copper wires cannot transmit information. Without Pattern there would be no established format for the signals. And timing lets the devices know when the pattern starts and ends.

Pharmaceutics Experiment 2 Preparation of a Hand Cream OBJECTIVE 1. To learn the method of preparing a hand cream. 2. To appraise the function of the ingredients in the hand cream. BACKGROUND Cream is a kind of dosage form and particularly hand cream is formulated to carry out a variety of cosmetic functions. Among these are softening and moisturizing the skin; elimination of natural waste products (oils) by emulsification; and cooling the skin by radiation‚ thus helping to maintain body temperature
