Biological Molecules and Lab Safety: Benchmark I Preparation

Prepare for Benchmark I in Biology by learning about biological molecules, measurement tools, experimental controls, and lab safety practices. Brush up on key concepts like acids and bases, nucleic acids, proteins, and enzymes. Ensure a thorough understanding of rates of reactions, proper measurement units, and toxin identification. Get ready for lab experiments with insights on control groups, microscopy tools, and the importance of using safety gear like goggles. Benchmark I is on Monday - be ready with this comprehensive guide!

Presentation Transcript

  1. Biology Benchmark I Biological Molecules

  2. Control Groups • Are used to compare your results to the experimental group

  3. Experiment • A scientist is testing mild for the presence of bacteria. Exactly 100 ml of a test solution must be added to each milk sample. Which of these instruments would most accurately measure the volume of the test solution?

  4. Measurement • Which unit is best for measuring the height of a newly sprouted plant?

  5. Water Is polar And a universal solvent

  6. Acids and Bases

  7. Double Helix

  8. Nucleotide

  9. Microscopes

  10. Proteins • Are made up of amino acids

  11. Vitamin D • Responsible for proper bone formation

  12. Enzymes • Help to speed up chemical reactions • Help to break down substances

  13. Nucleic Acids • Store hereditary information • Are found in our • DNA

  14. Carbohydrates • Are a good source of food • Are found in starches

  15. Toxins any poison produced by an organism, characterized by antigenicity in certain animals and high molecular weight, and including the bacterial toxins that are the causative agents of tetanus, diphtheria, etc., and such plant and animal toxins as ricin and snake venom.

  16. Rates of Reactions • Are affected by temperatures: • Colder temperatures slow down reactions • Warmer temperatures speed up reactions • As pH decreases so • will reaction rates

  17. Lab Safety • Wear goggles when using chemicals and glass • Know your safety symbols

  18. Benchmark I on Monday
