Chapter 1 Flashcards
Biosphere
All regions of earth where organisms live
Atoms
Fundamental building block of all matter
Community
All populations of species in a given area
Ecosystem
Community interacting w environment
Emergent propert
Characteristic of a system that does not appear in any of the systems component parts
Molecule
Association of two or more atoms
Organ
In multicellular organisms group of tissues in collective task
Organ system
Set of organs engaged in collective task that keeps the body functioning properly
Population
Group of individuals of the same species that live in a given area
Tissue
In multicelled organisms specialized cells organized in a pattern that allows a collective function
Ecosystem
Community interacting with its physical environment through transfer of energy and materials.
Consumer
Organism that gets energy and nutrients by feeding on tissue, waste, or remains of other organisms
Development
Multistep process in which first cell of a new individual becomes a multicelled adult
DNA
Dioxyribonucleicacid carries hereditary information
Energy
Capacity to do work
Growth
In multicelled species increase in number size and volume of cells
Homeostasis
Set of processes in which organism keeps it’s internal conditions w in tolerable ranges
Inheritance
Transmission of DNA from parents to offspring
Nutrient
Substance organism needs for growth and survival but can’t make self
Photosynthesis
Process by which producers use light em to make sugars from co2 and h2o
Producer
Organism that makes it’s own food using me and simple raw materials from the environment
Reproduction
Processes by which parents produce offspring
Animal
Multicelled consumer that develops through a series of stages and moves about during part of all of their life cycle
Archean
Member of a group of single celled organisms that differ from bacteria
Bacterium
Member of a large group of single celled organisms
Biodiversity
Variation among living organisms
Eukaryotes
Organism whose cells characteristically have a nucleus
Fungus
Type of eukaryotic consumer that obtains nutrients by digestion and absorption outside the body
Nucleus
Double membraned sac that encloses a cells DNA
Plant
A multicelled typically photosynthetic producer
Protist
Member of a diverse group of simple eukaryote
Genus
A group of species that share a unique set of traits, also the first part of a species name
Specific epithet
Second part of a species name
Taxon
Linnaean category a grouping of organism
Taxonomy
The science of naming and classifying species
Control group
Individual who are not exposed to the independent variable
Critical thinking
Judging information before accepting it
Data
Experimental results
Deductive reasoning
Using a general idea to make a conclusion
Dependent variable
Variable affected by independent variable
Experiment
Test to support or falsify a prediction
Experimental group
Group of individuals exposed to an independent variable
Inductive reasoning
Conclusion bases on observation
Model
Analogous system used to test a hypothesis
Prediction
Statement based on hypothesis about a condition that should exist
Science
Systemic study of the observable room
Scientific method
Making testing and evaluating hypothesis
Variable
A characteristic or event that differs among individuals over time
