Study Notes
Biological Diversity
- Natural Selection: Occurs when environmental factors influence which individuals within a species survive and reproduce. Desirable traits are chosen by the environment.
- Artificial Selection: Humans influence which traits are passed on through breeding or genetic engineering, creating desirable characteristics.
- Biotechnology: Techniques that involve intervention to select desirable traits. Examples include cloning, artificial insemination, in vitro fertilization, and genetic engineering.
- Variation: Differences in traits within a species. Variation can be heritable (passed genetically) or non-heritable (acquired).
- Genetic Code: DNA contains the instructions for heritable traits. Chromosomes and genes carry specific sets of instructions (alleles).
- DNA: Deoxyribonucleic acid. Holds genetic code.
- Genetics: The study of how traits are passed down through generations. Explains how heritable traits are passed on.
- Meiosis: Cell division that produces genetically different/ unique sex cells. Happens in reproduction.
- Mitosis: Cell division that creates identical copies of a cell used for growth and repair.
- Impact on Biodiversity: Natural and human factors influence biodiversity. Natural factors include disease, changes in environment. Human factors include habitat disruption, introduction of species.
- Ecosystems and species: Species live in ecosystems, having specific roles. Competition, interdependence (symbiosis), commensalism, mutualism, and parasitism are relationships between species and ecosystems.
- Variation of traits: Traits can be discrete (distinct categories) or continuous (a wide range of possibilities), some are heritable the others are not.
Electrical Technologies and Principles
- Static Electricity: Charges that build up on materials.
- Current Electricity: Continuous flow of electrons.
- Electrical Circuits: A closed path for electron flow. Includes load, energy source, and conductors.
- Energy: Capacity for doing work.
- Energy Transformation: Changing from one form to another.
- Electrical Safety: Important procedures and regulations to prevent accidents.
- Ohms Law: Describes relationship between voltage, current and resistance. V = I x R
- Cells: Provide energy in circuits.
- Circuits: Series and parallel circuits differ in how components are connected to each other. Series has single pathway; parallel has multiple pathways.
- Electrical Safety: Important measures to prevent accidents.
- Resistors: Resist current flow.
