Body Systems and Responses

  1. When you are injured, the immune system is activated to fight infection. Which organ system helps transport immune cells to the affected area?
    2. Lymphatic System
  2. How do the circulatory system and immune system work together to respond to an injury?
    3. Increased blood flow carries white blood cells to the site of the injury.
  3. A deer hears a predator approaching and begins to run for safety. The deer has primarily engaged what body system to escape?
    4. Nervous, respiratory, and muscular
  4. Which of the following is an example of the endocrine system directly interacting with the nervous system?
    5. Hormones provide feedback that affects the neuron processing.
  5. How does the digestive system work with all other systems?
    6. The digestive system gives the body energy and nutrients.

Evolution and Natural Selection

  1. Each living species has descended, with changes, from other species over time, and as a result, species today look different from their ancestors.
    2. Evolution
  2. Which of the following factors can increase the rate of evolution in a population?
    3. Stable environment with low competition. Bottleneck effect. Gene flow.
  3. What is the difference between natural selection and artificial selection?
    4. Natural selection occurs in nature, while artificial selection is conducted by humans. Natural selection favors traits that benefit survival and reproduction, while artificial selection favors traits that humans find desirable.
  4. According to the Theory of Evolution, organisms change during their lifetime to survive then pass these changes to their offspring. Who proposed the Theory of Use and Disuse?
    5. Jean Baptiste de Lamarck
  5. The diagram that traces evolutionary relationships and connections among organisms.
    6. Phylogenetic tree
  6. What letter represents the root?
    7. K
  7. What biotic relationship occurs in an organism where one species is benefited while the other is harmed?
    8. Parasitism
  8. What are the two important relationships in an ecosystem?
    9. Interaction and interdependence
  9. Which of the following conditions does NOT show abiotic factors in an ecosystem?
    10. A young woman gave birth to a healthy baby boy.
  10. The carrying capacity is the maximum number of organisms that an ecosystem can support. What factors influence the carrying capacity?
    11. I. Competition, III and IV
  11. What factors control the increase in population growth?
    12. II, IV, V, VIII. II. Limiting factor. III. Biotic potential. IV. Environmental resistance.
  12. The biotic and abiotic factors that prevent the growth of a population like food, water, and space is called?
    13. Limiting factor.
  13. In a symbiotic relationship, two species interact closely. Which type of symbiosis benefits both species involved?
    14. Mutualism
  14. What is the connection between biotic potential and environmental resistance?
    15. Biotic potential increases the population while environmental resistance decreases its growth.
  15. Which of the following best describes the concept of interdependence?
    16. The sharing of resources and responsibilities within a group of individuals.
