GeneticsPedigree and non-Mendelian practice problems1. Only individuals with the affected phenotype are shown in the pedigree below, no other individuals are indicated. What might be the mode of inheritance for the affected (shaded) individuals? Be sure to explain what evidence in the chart supports your conclusion? Use the roman numerals thatindicate generation and the Arabic numbers for individual.2. Only individuals with the affected phenotype are […]

In this activity, you will study the effect of pH, temperature and lactose concentration on lactase activity. By the end of this activity, you should be able to:design experiments to study the effects of pH, temperature, and substrate concentration on enzyme activity.graph data related to enzyme activity.analyze data related to enzyme activity.complete a lab write-up summarizing and analyzing your results for the effect of temperature […]

#1. Choose two different Nutrition Facts labels you saved from two different grocery store items. You may want to choose one from a food that you think is healthy, & one from a food you think is not as healthy nutritionally. Then, for each one: list parts of the food label you think are important; include additional comments regarding the different sections of the food […]

You have just seen a patient with probable Down Syndrome and one with Cystic Fibrosis and need to order tests to confirm the diagnosis. Using the lab tests listed below for each syndrome, please indicate what information is revealed by the test and what is still needed to obtain the most information. You may include a figure of the data from the test (but not […]

You have a patient that was recently diagnosed with cat-eye syndrome, and the parents are very confused about this disorder and particularly about the genetics. The parents took an AP biology course previously and do have some knowledge of the terms. They are having some difficulty understanding recombination and how this gene duplication occurred. They would like some general information about the syndrome, and what […]

BiologyBIOLOGICALLY IMPORTANT MOLECULES LABBio 121Introduction: There are 4 categories of organic compounds found in livingorganisms: Carbohydrates, Proteins, Lipids & Nucleic Acids. Each of thesemacromolecules is made of smaller subunits. These subunits are linked by dehydrationsynthesis, which is an energy-requiring process in which a molecule of water is removedand the two subunits are covalently bonded. View the following video for an introductionto these biomolecules. https://www.youtube.com/watch?v=QWf2jcznLsY&t=24sWhich of […]

BiologyProteins: Biuret test. Proteins are made of amino acids, each of which has anamino group (-NH2), a carboxyl (acid) group (-COOH), and a variable side chain. Apeptide bond forms between the amino group of one amino acid and the carboxyl groupof an adjacent amino acid. Proteins are identified by a Biuret test. Peptide bonds (C – Nbonds) in proteins complex with Cu2+ in Biuret reagent […]

Biology BiologyLipids: Sudan IV test. Lipids include a variety of molecules that dissolve in non-polar solvents such as ether, acetone, methanol, or ethanol, but not as well in polarsolvents such as water. Triglycerides (fats) are abundant lipids made of glycerol andthree fatty acids. Tests for lipids are based on a lipid’s ability to selectively absorbpigments in fat-soluble dyes such as Sudan IVSeveral solutions and their […]

1. (2) What is the source of electrons in the mitochondrial electron transport chain? And where do the electrons end up once they pass through the chain? 2. (2) Molecules called uncouplers (such as dinitrophenol) poke holes in the inner mitochondrial membrane. What effect would this have on aerobic respiration? 3. (2) Define “exogenous” and “endogenous” electron acceptors. 4. (4) The conversion of pyruvate to […]
