Study Notes
Environmental Pollution
- An unnatural increase in concentrations of environmental compounds such as heavy metals, radionuclides, nitrates, phosphates, cyanides, agricultural wastes, sewage, pathogens, gases, and particulates.
Invasive Alien Species (IAS)
- Exotic micro- and macro- species introduced accidentally or deliberately to a place that is not part of their natural habitat or distributional range.
Threats to Biodiversity
- Habitat Destruction
- Exploitation
- Overpopulation
- Non-native species
- Global Climate Change
- Pollution
- Human Activities
Genetically Modified Organisms (GMOs)
- Genetically Modified Organisms
- Use of vectors (plasmids or cosmids) to accept foreign DNA for transformation
- Plasmid: an extra-chromosomal element capable of independent replication
- Restriction Enzyme: an enzyme that cuts DNA
- Cloning: a technique used to alter or move genetic material (genes) of living cells
Biotechnology
- Bacillus Thuringiensis (BT): a toxin inserted in corn to resist pests and pesticides
- Genetically modified corn, cotton, and cassava
- Golden Rice: modified rice containing beta-carotene
- Jatropha: a plant similar to palm oil
Biodiversity and Ecology
- Biodiversity: the multitude of living organisms and how they interact with each other and their environment
- Habitat: the physical environment to which a species has become adapted
- Niche: the role of a species as a producer and consumer of food resources
- Species: a group of interbreeding organisms with the same structures
- Extinction: the total disappearance of a species
- Genetic Diversity: variation or differences in the genes of a species or individual
- Species Diversity: diversity of number of species
- Community Diversity: variety of ecosystem in a given region
Nanotechnology
- Nano: billionth of a quantity, represented mathematically as 1 × 10^(-9)
- Nanotechnology: a new area of scientific research focusing on particles too minute to be seen
- Nanomaterials: minute particles
- Nanoethics: the study of the ethical and social dimensions of nanotechnology
Genetics
- Gene: the unit of heredity
- Genetic Disorder: a disease caused by an abnormality in an individual's DNA
- Vector: an organism that does not cause disease itself, but which carries the DNA from one host to another
- Defective gene: a gene that does not work properly
- Stem Cell: a class of undifferentiated cells that are able to differentiate into specialized cell types.
