Study Notes
Genetic Mutation
- A genetic mutation is a change to genetic material that can result in disorders.
Ecological Concepts
- Deforestation: the removal of forests.
- Succession: a process of change in species composition of a biological community.
- Primary succession: occurs in areas where no previous community existed.
- Secondary succession: occurs in areas where a community has been disturbed or destroyed.
Cell Division Phases
- Prophase: the first stage of mitosis, where chromatin condenses into visible chromosomes.
- Metaphase: the second stage of mitosis, where chromosomes line up at the center of the cell.
- Anaphase: the third stage of mitosis, where sister chromatids separate and move to opposite poles.
- Telophase: the fourth stage of mitosis, where nuclear envelopes reform and chromatin uncoils.
Cell Division Types
- Mitosis: the division of normal body cells, consisting of interphase, PMAT, and cytokinesis.
- Meiosis: the division of sex cells, resulting in gametes with half the number of chromosomes.
Cell Structure
- Prokaryotic cells: lack a nucleus, found in single-celled organisms like bacteria.
- Eukaryotic cells: have a nucleus, found in plants, animals, fungi, and protists.
Physiological Concepts
- Homeostasis: the maintenance of a stable internal environment despite external changes.
- Stimulus: something that causes a response, such as light, temperature, or touch.
- Response: the reaction caused by a stimulus, such as a muscle contraction or a change in heart rate.
