Chapter 1 Flashcards
Biology
The study of life
In Life’s Hierarchy of organization…
New properties emerge at each level
With addiction of each new level, Novel properties emerge called
Emergent properties
Atoms
The fundamental building blocks of all substances
Molecules
Clusters of atoms
Organelles
Membrane - Bound structures with specific funtions1
Cells
Smallest unit of life. Living entities distinguished from their environment by a membrane
Lower tier, What makes a cell?
Atoms, Molecules, Organelles, and Cells
The middle tier
Tissues, Organs and Organisms
Tissues
Made of groups of similar cells organized in a particular pattern
Organs
Structural unit of interacting organs that keep the body functioning
The Upper tier
Population, Community, Eco system and Biosphere
Population
All the individuals within a specific area
Comminuty
The array of organisms living in a particular eco system
Biospshere
All the Environments on Earth that support life
Ecosystem
All the organisms living in a particular area
Photosynthetic organisms provide food and are called
Producers. Ex: Plants
Organisms that eat plants or animals are called
Consumers Ex: Humans, Bears
Nutrients
Are recycled between producers and consumers
Energy
Is not recycled, through the organisms, and back out to the environment
Homeostasis
The process that any living things use to actively maintain fairly stables conditions necessary for survival.
Chance and respond to their environment
Bacteria
Single cells, No nucleus
Most ancient lineage
Archaea
Single cells, No nucleus
Evolutionarily closer to Eukaryotes than Bacteria
Eukarya
Eukarya Cells (with Nucleus)
Single cells and multi - celled species of protists, plants fungi and animals
Inductive reasoning
A form of logical thinking that uses related observation to arrive at a general conclusion , based of evidence.
To observe, explore and discover
Deductive reasoning
A form of logical thinking that uses general principle or law to forecast specific results. :hypothesis based science
Scientific theory
Hypothesis that has not been disproven after many years of rigorous testing
Law of Nature
Generalizations that describes a consistent natural phenomenon for which there is complete scientific explanation
Sampling Error
Difference between results obtained from a subset, and results from the whole
