Term
Seven Properties of Life
Definition
1. Order,
2. Regulation,
3. Growth and development,
4. Energy processing,
5. Response to the environment,
6. Reproduction,
7. Evolution
Term
Biology
Definition
Scientific Study of Life
Term
Order
Definition
All living things exhibit complex but ordered organization, example pinecone
Term
Regulation
Definition
The environment outside an organism may change drastically, but the organism can adjust its internal environment keeping it with appropriate limits
Term
Growth & Development
Definition
Information carried by DNA controls the pattern of growth and development in all organisms
Term
Energy processing
Definition
Organisms take in energy and use it to perform all of life's activi[image]ties they emit energy as a heat
Term
Response to the environment
Definition
All organism respond to environmental stimuli.
Term
Reproductoin
Definition
Organisms reproduce their own kind, - a process by which an organism perpetuates itself and its species
Term
Evolution
Definition
Reproduction under lies the capacity of populations to change -evolve- over time
Term
Biosphere
Definition
All life and all the places where life exists
Term
Ecosystems
Definition
Consists of all living organisms in a particular area and all the nonliving components of the environment with which life interact, such as soil, water, and light
Term
Communities
Definition
All organisms in the tide pool - iguanas, crabs, seaweed, bacteria, and others- are collectively called a community
Term
Populations
Definition
Within communities are various populations, groups of the interacting individuals of one species, such as a group of iguanas
Term
Organism
Definition
An organism is an individual living thing like iguana
Term
Organ systems and organs
Definition
An organism's body consists of several organ systems, each which Contains two or more organs
Term
Tissues
Definition
Several different tissues, such as the heart muscle tissue. A tissue consists of group of similar cells performing a special function
Term
Organelles
Definition
Are functional components of cells , such as the nucleus that houses the DNA
[image]
Term
Cells
Definition
The cell is the smallest unit that can display all the characteristics of life. The cell has a special place in the hierarchy of biological organization

[image]
Term
Molecules
Definition
The chemical level in the hierarchy.
Molecules are clusters of even smaller chemical units called atoms, Chemicals that result from atoms linking together
Term
Atoms
Definition
Each cell consistent if an enormous number of chemicals that function together to give the cell the properties we recognize as life.
Term
DNA
Definition
The molecule of inheritance and the substance of genes.
Deoxyribonucleic acid,
Term
Ecosystem
Definition
each organisms interacts continuously with their physical environment as well as nonliving factors.
Term
Nutrients
Definition
Nutrients are recycled within an ecosystem
Term
Energy
Definition
Energy flows into and then out of an ecosystem
[image]
Term
Two major kinds of cells
Definition
Prokaryotic and Eukaryotic
Term
Prokaryotic cells
Definition
.Small,
.Simple structure,
.DNA concentrated in nucleoid region, which is not enclosed by membrane,
.Lacks most organelles

[image]
Term
Eukaryotic cells
Definition
Larger,
.More complex structure,
.Nucleus enclosed by membrane,
.Contains many types of organelles

[image]
Term
Prokaryotic are much simpler
Definition
usually much smaller than the eukaryotic cell. Bacteria are prokaryotic
Term
Eukaryotic cell is subdivided by internal membranes
Definition
Most of other forms of life, including plants and animals, are composed of eukaryotic cells
Term
The language of DNA
Definition
Every molecule of DNA is constructed from four kinds of chemical building blocks that are chained together
Term
The four chemical building blocks of DNA are abbreviated as
Definition
A,
G,
C,
T.
An average-sized gene may be hundreds or thousands of chemical "letters" long.
Term
gene's meaning
Definition
to a cell is encoded in its specific sequence of these letters, just as the message of a sentence is encoded in its arrangement of letters selected from the The English alphabet.
Term
The Human body is made up of
Definition
Eukaryotic
Term
The three domains of life
Definition
Bacteria,
Archaea,
Eukarya
Term
The first two domains
Definition
Bacteria and Archaea, indentify two very different groups of organisms that have Prokaryotic cells
Term
The third domain
Definition
Eukarya,
which includes three kingdoms:
Plantae, Fungi, and Animalia Which we belong.
Term
Those Eukaryotes that do not fit into any of the three kingdoms are referred to as the PROTISTS.
Definition
Protists are single celled: they include microscopic protozoans, such as amoebas. But protists also include certain multicellular forms, such as seaweeds.
Term
Darwinian View of life
Definition
Modern terms of what Darwin called 'descent whit modification?Evolution-- Natural Selection
Term
Natural selection
Definition
A process in nature in which organisms possessing certain inherited traits are better able to survive and reproduce compared to others of their species.
Term
What mechanism of Darwin propose for evolution
Definition
natural selection
Term
What three word phrase summarizes Darwin Mechanism
Definition
unequal reproductive success
Term
The Word science is derived from a Latin verb meaning
Definition
to know
Term
Discovery science is
Definition
Data verifiable observation and measurements
Term
the scientific method in their order are
Definition
Observation,
Question,
Hypothesis,
Prediction,
Experiment,
Results,
Revise and Repeated
Term
Controlled experiment
Definition
A test of the effect of a single variable by changing it while keeping all other variables the same.
