Meal Worm Cellular Respiration Experiment Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the

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

Experiment 21: Salmonella and food contamination Purpose /Objective Objective: To test salmonella in spinach sample over five lab periods. Food contamination of salmonella can cause serious illness. Only small numbers of salmonella need to be found for a food product to be considered contaminated. Tests used Pre-enrichment- lactose broth Selective enrichment broth- with Tetrathionate Brilliant Broth Selective Plating- Brilliant Green Agar Isolation of salmonella conformation- is preformed

Percent Acetic Acid in Vinegar Introduction: Acetic acid is reactive when combined with calcium carbonate. In this lab‚ we will use vinegar for its acetic acid and egg shells for their calcium carbonate. Marketable vinegar differs in its acetic acid concentration from 4-6%. Calcium carbonate reacts with the acetic acid in vinegar to produce carbon dioxide‚ water‚ and calcium acetate as represented by the equation: CaCO3 + 2HC2H3O2 CO2 + H2O + Ca(C2H3O2)2. The calcium carbonate reacts with
