What topics are covered in the key units?
Use the following topics as key words in other search engines or your text book and notes to help you study. They are all the topics covered during class or in your reading.
Scientific Methods and Reasoning
Good science involves referring, experimenting, finding evidence, collecting and organizing data, drawing valid conclusions, and undergoing peer review.
Key words: scientific method, experimental design, hypothesis, control, independent and dependent variables
Maintenance among organisms:
Organisms must maintain homeostasis (balance). To do so they use cells, tissues organs and body systems. We will also cover the lack of homeostasis: diseases and conditions, i.e. AIDS.
Key words: cell organelles and life processes, diffusion, osmosis and active transport, Human Physiology, body systems, disease
Genetics and heredity
All organisms are able to pass on traits to the next generation. How and when they do this is covered within genetics.
Key words: population genetics, DNA and RNA, protein synthesis, Mendel's rules of heredity, genetic engineering and other concepts in biotechnology, including cloning and current medical applications of genetics.
Reproduction and Development
All organisms sustain the continuity of life through reproduction and development. Yes. SEX. However, we will see organisms that use different types of methods to reproduce- everything from the natural clones of plants to the "buddies" of hydras.
Key words: reproduction, asexual, sexual, cloning, mitosis, meiosis, cell division, internal and external development.
Evolution
Individual organisms and species change over time. This topic includes some highly charged debates- we will respect all opinions during this topic.
Key words: Darwin, adaptations, survival of the fittest, natural selection, population dynamics, origins of life, punctuated equilibrium versus gradual, heterotroph hypothesis.
Ecology
Plants and animals depend on each other and their physical environment; human decisions have a profound impact on the physical and living environment.
Keywords: abiotic factors, biotic factors, pollution, biomes, energy cycles, nitrogen cycle, water cycle, food webs.
