Study Notes
Ecology
- Study of the relationships between organisms and their environment
- Focuses on the interactions between living organisms (biotic factors) and non-living components (abiotic factors) in an ecosystem
- Key concepts:
- Ecosystem: a community of living and non-living components interacting with each other
- Biodiversity: the variety of species, genes, and ecosystems in an environment
- Ecological niche: the unique role and position of a species in its environment
- Food webs: networks of predator-prey relationships
- Energy flow: the transfer of energy from one trophic level to another
Biotechnology
- The application of biological principles to develop new products, technologies, and processes
- Involves the use of biological systems, living organisms, or derivatives to make or modify products
- Key concepts:
- Genetic engineering: the manipulation of an organism's genome to introduce new traits
- Recombinant DNA technology: the use of DNA molecules from different sources to create new DNA sequences
- Cloning: the creation of an exact copy of an organism or DNA sequence
- Bioproducts: products derived from biological sources, such as enzymes, vaccines, and pharmaceuticals
Human Physiology
- The study of the functions and processes that occur within the human body
- Focuses on the maintenance of homeostasis and the regulation of bodily functions
- Key concepts:
- Homeostasis: the maintenance of a stable internal environment despite changes in the external environment
- Organ systems: groups of organs that work together to perform specific functions
- Nervous system: the system responsible for transmitting and processing information
- Endocrine system: the system responsible for producing and regulating hormones
- Circulatory system: the system responsible for transporting oxygen and nutrients to cells and removing waste products
Plant Physiology
- The study of the functions and processes that occur within plants
- Focuses on the growth, development, and responses of plants to their environment
- Key concepts:
- Photosynthesis: the process by which plants convert light energy into chemical energy
- Respiration: the process by which plants break down glucose to produce energy
- Transpiration: the process by which plants transport water and nutrients from roots to leaves
- Hormone regulation: the role of plant hormones in regulating growth and development
- Defense mechanisms: the ways in which plants respond to pathogens and environmental stressors
Genetics
- The study of heredity and variation in organisms
- Focuses on the transmission and expression of genetic information
- Key concepts:
- DNA: the molecule that contains the genetic information of an organism
- Genes: the units of heredity that encode specific traits
- Alleles: different forms of a gene that occupy the same position on a chromosome
- Genotype: the genetic makeup of an organism
- Phenotype: the physical and behavioral traits expressed by an organism
- Inheritance patterns: the ways in which genetic traits are passed from one generation to the next
