Interrelationships
In this unit, we learned about pathogens, immunity, ecology and the nitrogen cycle. I do not have pictures of the Chapter quizzes and tests.

In Chapter 12, we learned about different diseases. I got a 90% on the vocabulary quiz and 92% on the test. We were tested on our knowledge about the names and types of causative organism of each of the following diseases: cholera, malaria, TB, HIV/AIDS, smallpox and measles. We were required to state how cholera, measles, malaria, TB and HIV/AIDS are transmitted.

In Chapter 13, we learned about the immune system. We were required to state the origin and describe the mode of action of phagocytes (macrophages and neutrophils) and describe the modes of action of B-lymphocytes and T-lymphocytes. On the test, I was able to distinguish between active and passive, natural and artificial immunity and explain how vaccination can control disease.

In Chapter 14, we learned about ecology. We learned about the following terms habitat, niche, population, community and ecosystem and be able to recognize examples of each. We were rquried to explain the terms autotroph, heterotroph, producer, consumer and trophic level in the context of food chains and food webs and explain how energy losses occur along food chains and discuss the efficiency of energy transfer between trophic levels.
