Introduction Biology Flashcards
What are the 7 properties of life?
- Order
- Sensitivity/ Response to the environment
- Reproduction
- Growth & development
- Regulation
- Homeostasis: Regulation internally
- Energy processing
Energy Processing
Organisms using a source for metabolic activities (Living things using energy)
Photosynthesis & Cellular respiration
Regulation
Organisms coping with environmental stress
Atoms
Fundamental unit of matter
What is the order of arrangements from atoms to organ system
Atoms -> molecules/ macromolecules - > organelles - > tissue -> organs -> organ system
what do all cells have?
Plasma membrane
cytoplasm’s
DNA
ribosomes
Hypothesis
Has to be testable & falsitable
helps us make predictions
Experimental variables
Independent & Dependent
Experimental design
Sample size & Selection
key: Avoiding bias
Population
Members of the same species
Ecosystem
non-living and living things
Community
Collection of populations in an ecosystem
Prokaryotic cells
- No nucleus
- No membrane bound Organelles
- Cell wall
- Flagella
- Smaller
- unicellular
Genetic diversity
Most precise and specific measure
Diversity within a population
Differentiating different populations
Species diversity
*biodiversity
Number of different species in a ecosystem
Reporting what can be found in an area
Ecosystem diversity
Living communities interacting with their environment
- broader
Phylogenetic trees
Showing relationships within the three domains of life
evolution & shared ancestry
Relationships of an organisms to another
A convincing scientific study should rule out a _____
Random chance
What is taxonomy
Taxonomy is the science of classifying organisms.
Taxonomy groups
Domain
Kingdom
phylum
class
order
family
Genus
species
Binomial nomenclature
Genus + Species = Name
universal and standardized naming system for scientists
Biotechnology
how to use biological processes, for example manipulating micro-organisms to produce medicines
Paleontology
history of life using fossils
Molecular biology and Biochemistry biological
processes at the molecular and chemical level.
Microbiology structure
Function of single-celled organisms.
Neurobiology
the nervous system
Zoology
Botany
Genetics
Animals
Plants
heredity and genes
Ecology
how organisms interact with other organisms and with their environment
Forensic Biology
applications of biology to law
Physiology
functions of organisms and their parts
3 Domain of life kingdoms
Bacteria
Archaea
Eukarya
