1. Question: You are given the following pH values: Solution 1: 9.2, Solution 2: 4.8, Solution 3: 12.7, Solution 4: 1.1 a. Which solutions are basic? b. Which solution would have the highest concentration of H3O+ ions when dissolved in water? 2. Question: You are given three compounds: NaCl, CH3CH2OH (ethanol), and CaCl2. You are asked to measure out 14.7 g of each compound into three separate 500-mL flasks and add enough water to make 500-mL of solution. A chemist comes along and measures th...

Station 1. You have run an experiment studying the effects of the molecular weight of a compound on the rate of diffusion in agar. Compound X has a molecular weight of 25.3 g/mol and compound Y has a molecular mass of 156.2 g/mol. On two separate agar plates, 0.1 g of each substance were transferred and allowed to diffuse for 2 hours. The results below were obtained. Use this information about this situation to answer the following three questions. 1. Question: (CO 1) What was the independent v...

Learning Objectives • Explain the translation process from mRNA to amino acid • Explain post-translational modification of proteins • Explain protein synthesis processing in the ribosome • Explain the primary, secondary, tertiary and quaternary structures of protein • Explain the basic principles of mass spectrometry (MALDI-TOF) Introduction In the Protein Synthesis lab, you will learn about the difference between protein synthesis in prokaryote (using E. coli) and eukaryote (us...

Learning Objectives • Understand the types of macromolecules found in food • Understand the structure of carbohydrates, proteins, and lipids • Detect macromolecules in food samples Introduction Macromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance in food.

1. Choose a specific biomolecule found in your diet. What is the source and purpose of this biomolecule?

Week 7 Discussion: Flow of Genetic Information Genetics in forensic science Option 2: Genetics is a rapidly evolving area of science. Each year advances in genetics bring exciting new technologies to the market. Areas such as forensics, genealogy, and healthcare have all been affected by new genetic technologies. Choose a genetic technology and report on how this technology is affecting or will affect our lives. Give at least one outside source and cite in APA format.

In this concept, we will discuss one class of biological polymers called lipids or fats. You might be familiar with this class of biopolymers, which are found in butters and oils. We will discuss saturated and unsaturated fats, and what those terms mean for the molecule's structure as well as its properties at room temperature. 1. Which of the following is a source of lipids?
