  2. Question 1 • What is the easiest way to successfully classify one prokaryotic kingdom from the other? • The components of its cell wall

  3. Question 2 • Having a widow’s peak is a dominant trait in humans. Charlie has a widow’s peak but his sister does not. What must their parents genotypes be for this outcome? • Ww and Ww

  4. Question 3 • How many offspring have the genotype RrYy? • 4 • How many offspring have the phenotype of round & green? • 3 • What are the recessive traits? • Wrinkled and green

  5. Question 4 • What percentage of the offspring are heterozygous? • 50% • What percentage of the offspring are homozygous? • 50%

  6. Question 5 • What is a homologous structure? • Anatomical structures that have similar ancestry but do not perform the same functions. • Give an example. • Whale fin and human arm

  7. Question 6 • What parts of classification make up the scientific name? • Genus and species names • Two organisms within the same family can be organized into different - ? • Genera (genus plural)

  8. Question 7 • What is the benefit of mutations? • Mutations create genetic diversity

  9. Question 8 • What is genetic drift? • Genetic drift refers to random changes in the gene frequencies in small populations. • Reduces genetic variation • Fewer opportunities for natural selection

  10. Question 9 • What would be an effective way for a viral medicine to limit the spread of a virus? • Stop the virus from attaching to the target cell • What is a similarity between viruses and cells? • Genetic material

  11. Question 10 • What is the purpose of antibiotics? • Kill (destroy) bacteria • How do bacteria harm host? • Destroy tissues for food • Create toxins that harm organisms

  12. Question 11 • What can plants do for an ecosystem that is not possible for other organisms in a typical ecosystem? • Photosynthesis • What are the types of energy being converted in photosynthesis? • Radiant energy to chemical energy

  13. Question 12 • When cones or flowers are removed from a plant what will be interfered with? • Reproduction

  14. Question 13 • What part of the plant intakes oxygen? • Leaves • What do we call the opening on the bottom of the plant? • Stomata

  15. Question 14 • What 2 body systems are responsible for homeostasis? • Nervous and endocrine

  16. Question 15 • What plant structure is responsible for transporting sugars? • Phloem • What plant structure is responsible for transporting water? • Xylem

  17. Question 16 • What is a retrovirus? • RNA virusthat replicates in a host cell through the process of reverse transcription. It replicates backwards compared to other viruses. • What are some examples of viruses? • Flu, common cold, HIV, hepatitis…..

  18. Question 17 • Identify the content of the cell wall of the following kingdoms: • Plantae • Cellulose • Fungi • Chitin • Bacteria • Peptidoglycan

  19. Question 18 • Xylem cells in plants transport water and minerals and it also gives the plant structure. What two human body systems perform similar functions in the human body? • Circulatory and skeletal systems

  20. Question 19 • What are some functions of the fruit found in plants? • Dispersal of seeds • Seed protection • Source of food for other organisms

  21. Question 20 • Which system is responsible for controlling the reproductive system? • Endocrine system • Which system transport hormones from gland to target cells? • Circulatory system • Which system is responsible for the immune system swiftly reaching foreign substances in the body? • Circulatory system

  22. Question 21 • Identify what “x’s” is in the levels of organization…. • Organism, system, x1, tissues, cells, organelles, x2 • X1 –organ • X2 –macromolecules

  23. Question 22 • Put the following in order from least inclusive to most inclusive: ecosystem, biome, community, population, individual, biosphere • Individual, population, community, ecosystem, biome, biosphere

  24. Question 23 • What do insulin and glucagon help to control in the human body? • Blood sugar levels • What organ produces insulin and glucagon? • Pancreas • How does the human body regulate body temperature when it is hot? • Sweating

  25. Question 24 • Identify some things that can decrease a predator population…. • Disease • Reduction in prey • More competition

  26. Question 25 • What does ADH control in the body? • Water in blood – hydration • How might a climber’s body adapt to high altitudes with less oxygen? • Increase breathing rate • Heart rate increases

  27. Question 26 • If an organism is multicellular, feeds on plankton and is eukaryotic…which kingdom does it belong to? • Animilia
