Growth: the increase in size and number of cells of an orgasms.
Development: all changes that take place between conception and death fertized eggs new born, adult ,aging
Adaptation: modifications that make an organism better suited to its way of life
a. Predators. built of speed and strength
b. Nocturnal. see good at night
Evolution: all living thing have a common ancestors and are adopted to a particular way of life.
Living thing belong to a population: group of different population form communities & communities interacting with their environment form of ecosystem.
Ecosystem: includes concept of interaction between population (food chain & exchange of gases with the physical environment.
Science: a human endeavor that considers what is the observable by the senses (smell ,touch,sound ,sight,taste, also pain chemical balance .sometime ...view middle of the document...
step 1 observation: simplify identifying some phenomenon.
Step 2 problem or question:usually ask the question why
Step 3 hypothesis: a tentative explanation to the question or problem based on past observation
Step 4 testing the hypothesis : experiment to prove or disprove the hypothesis.
Step 5 collection of data and analysis :result of experiment is known as data
Step 6 conclusion: result of experiment support or no
Step 7 theory : conceptual scheme supported by the board rahge of observation.
Control group: a second setup that have everything the same except for that being tested
Experiment: an artificial situation devised to test the hypothesis.
Repeatability of experiment: scientists must keep record that their experiment can be repeated.
1. Observation 2 previous data 3.formulation of hypothesis 4.observation and experimentation 5 new data- conclusion
Cellular: the cell is the basic unit of life
Cell theory : all organisms are composed of cells
Tissue: composed of similar cell which work together (muscular,connective)
Organs: group of tissue working together ( heart bicep stomach lung)
Organ system : (circulatory,digestive,reproductive) work together.
Organism: a living being capable of normal characteristics of life population .
Level of organisms : chemical molecules cells tissue organs organ system organisms population community ecosystem
Taxonomy: science of the classification of living thing the parts of biology dedicated to naming describing and organizing (kingdom phylum class order family genus species
Binomial nomenclature: the scientific name of an organism two work genus and species
Monera: microscopic single cells bacteria
Protista: complex single celled some multicelled protozoans
Fungi: molds yeast mushrooms
Plantae : plant
Animalia: invertebrates & vertebrates.
