Study Notes
Biological Terms & Concepts
- Homeostasis: The ability of an organism to maintain a stable internal environment.
- Response to Stimuli: A characteristic of life where organisms react to changes in their environment.
- Structure and Function: The relationship between the form of something (structure) and what it does (function).
- Gametes: The reproductive cells (sperm and egg) involved in sexual reproduction.
- Conjugation (Paramecium): A sexual process involving the exchange of genetic material between two compatible mating types.
- Budding (Yeast): An asexual reproduction method where a new organism grows from the body of an existing one.
- Inbreeding: Mating between closely related organisms.
- Genetic Engineering: Direct manipulation of an organism's DNA to achieve desired traits.
- Recombinant DNA Technology: Techniques used to create recombinant DNA.
- Genetically Modified Organism (GMO): An organism whose genetic material has been altered using genetic engineering techniques.
- Phenylketonuria (PKU): A genetic disorder affecting the metabolism of phenylalanine.
- Nervous System: Body system responsible for transmitting signals and processing information.
- Circulatory System in Sponges and Hydra: These organisms lack a circulatory system.
- Circulatory System (Mammals): Mammalian hearts have four chambers.
- Digestive System: Processes food for nutrient absorption.
- Circulatory System (for nutrients): Distributes absorbed nutrients to the body.
- Circulatory System (Fish): Uses gills to get oxygen from water.
- Respitory System (Fish): Extracts oxygen from water using gills.
