Study Notes
Biotechnology
- Definition: Biotechnology is the use of biological systems, living organisms, or derivatives thereof, to make or modify products for specific use.
-
Applications:
- Medicine: Vaccine development, gene therapy, and regenerative medicine.
- Agriculture: Genetically modified crops, pest resistance, and increased yields.
- Environment: Bioremediation, biofuels, and bioproducts.
Ecosystems
- Definition: A community of living and non-living components interacting with each other in a specific environment.
-
Components:
- Biotic factors: Living organisms (plants, animals, microorganisms).
- Abiotic factors: Non-living components (light, temperature, water, soil).
-
Types:
- Terrestrial ecosystems (forests, grasslands, deserts).
- Freshwater ecosystems (rivers, lakes, wetlands).
- Marine ecosystems (coral reefs, open ocean, estuaries).
Ecology
- Definition: The study of the relationships between organisms and their environment.
-
Key concepts:
- Population ecology: Study of population dynamics, growth, and decline.
- Community ecology: Interactions between different species in an ecosystem.
- Ecosystem ecology: Energy flow, nutrient cycling, and ecosystem processes.
-
Ecological levels:
- Individual: Organismal level.
- Population: Group of individuals of the same species.
- Community: Multiple species interacting in an ecosystem.
- Ecosystem: All living and non-living components in an environment.
Evolution
- Definition: The change in the inherited characteristics of a population of organisms over time.
-
Mechanisms:
- Natural selection: Differential reproduction due to environmental pressures.
- Genetic drift: Random changes in gene frequency.
- Gene flow: Movement of genes between populations.
-
Types of evolution:
- Microevolution: Changes within a population over a short period.
- Macroevolution: Large-scale changes over a long period, resulting in new species.
Genetics
- Definition: The study of heredity, genes, and genetic variation.
-
Key concepts:
- Genotype: Genetic makeup of an individual.
- Phenotype: Physical and behavioral traits of an individual.
- Dominance: One allele masks the effect of another allele.
-
Mendelian inheritance:
- Laws of inheritance: Segregation, independent assortment, and dominance.
- Punnett squares: Predicting offspring genotypes and phenotypes.
These notes cover the basics of biotechnology, ecosystems, ecology, evolution, and genetics, providing a solid foundation for further study in the life sciences.
