Biology Second Semester Exam Review

  1. Explain, and use a geneticist's tool, to show why and how a plant breeder can expect to cross a red rose with a white rose and produce roses of differing shades.

  2. How are Mendel's Laws of Heredity reflected in the process of mitosis, meiosis and the Chromosome theory?

  3. Evaluate predator/prey relationships in terms of the premises upon which Darwin based his theory of evolution.

  4. Using specific examples from this past semester, use the classification of organisms from simple to complex as either positive or negative evidence for the support of evolution.

  5. Describe the structure of a plant from the ground up and detail the specialized function for each structure mentioned.

  6. Reflect on the Kingdom Fungi relative to all other multicellular organisms.

  7. Pick any human system and describe how the four animalian tissues are used within that system.

  8. Discuss how any 3 human systems are dependent on the other 2 to complete its task.

  9. Describe the general sequence of animal development from the production of gametes to the formation of an embryo.

  10. You are a tiny free-living flatworm just evolved from Cnidaria about 400,000,000 years ago. Develop 2 different environmental scenarios that show how and why you continued to evolve as a free-living worm or as a parasitic worm.

  11. Illustrate an earthworm showing the major internal structure of 2 systems and explain the function of each structure.

  12. Discuss the advantage of a coelom using each of the major worm Phyla to lend evidence to your statements.

  13. When compared to Mollusks, in what ways are earthworms structurally superior, and in what ways might Mollusks be considered structurally superior to earthworms?

  14. Discuss the ways that the Cephalopods have adapted to life in the open ocean as both predator and prey.

  15. Describe the adaptations of the Class Insecta that have allowed them to fill every available terrestrial niche.

  16. Compare the distinguishing features of each Subphylum of the Phylum Arthropoda.

  17. Contrast the advantages of being a terrestrial Arthropod with the advantages of being a terrestrial Vertebrate.

  18. Compare the physiology of the major invertebrate systems with the major vertebrate systems.

  19. Describe and provide examples as to how natural selection has affected predator-prey relationships.

  20. Compare and contrast 3 kinds of symbiosis among organisms and give examples of each.

  1. What are some benefits of being an endotherm? What are some disadvantages?

  1. Trace a bite of food from the mouth as it travels through a human digestive system. Include both chemical and mechanical aspects of food digestion.

  1. Compare gas exchange in the following animals: (a) earthworm; (b) grasshopper; (c) fish; (d) frog.

  1. Contrast an open with a closed circulatory system and give examples of organisms that possess each type of system.

  2. List and describe 5 functions of the vertebrate circulatory system.

  3. Compare how nutrients and oxygen are transported to the body cells in a hydra, planarian, earthworm, insect, and frog.

  4. Give the function of each of the following structures within the human brain: (a) medulla; (b) midbrain; (c) cerebellum; (d) thalamus; (e) hypothalamus; (f) cerebrum.

  5. Outline a model for the sequence of events that causes a muscle cell to contract, beginning with the stimulation of its nerve and including cross bridge action.

  6. The skeleton transmits mechanical forces generated by muscle and also supports and protects an organism's body. If you were to create an “ideal” organism, would it contain a hydrostatic skeleton as found in most invertebrates, an exoskeleton characteristic of many mollusks and arthropods, or an endoskeleton as found in echinoderms and chordates? Support your answer.

  7. Imagine that you are suddenly approached by a fire-breathing dragon thought to be extinct … Explain the “fight or flight response” in terms of the nervous and endocrine systems.

  8. You are locked out of your car in a rural area, it's late at night, and there is at least a foot of snow on the ground. You can't get a hold of anyone because your cell phone battery is out. You have on jeans and a shirt, shoes, but no jacket. Which human body systems are going to help you survive until help can arrive? And describe how these systems will attempt to help your body maintain homeostasis.

  9. You are a famous biologist about to embark on a fact-finding trip to Mars with the mission of locating and classifying any living species you may find. What tools do you need to take (you can carry only a regular high school-sized backpack)? What criteria will you use to determine whether or not you have truly found a living or once living (fossil) thing? Once you make your great discovery, how are you going to classify the organism? Explain your classification answer in terms of cellular organization and 6 kingdom classification characteristics.

  10. Using the human body as a model, identify and describe examples of 1st, 2nd, and 3rd class levers used in various examples of human motion.
