The Theory that species change over time is ____?
|
Evolution
|
|
What is the definition of "Theme"?
|
A unifying idea that relates subordinate ideas to each other.
|
|
Adaptation
|
Relates to evolution because if conditions are putting pressure on populations, leading to evolution or extinction.
|
|
Theme of evolution relates to Theme of Ecology
|
Because changes in ecological relationships may put pressure on populations, leading to evolution or extinction.
|
|
Ethics
|
Must be part of biology because many ethical concerns relate to treatment of living things, including humans. Advanced technology in medicine and genetic engineering has the potential to affectc all living things. Ethics, must, therefore be an important part in biology.
|
|
7 Characteristics of living things:
|
Cell, organization, energy use, reproduction, adapation, response to environment, and growth.
|
|
Response
|
Relates to behavior because behavior is a complex kind of response.
|
|
Growth of Living and Non-Living Things
|
The difference between growth in living things and growth in nonliving things due to cell enlargement and division, while in nonliving things such as crystals, it's usually due to accumulation of atoms or molecules.

Phylogeny
|
A species evolutionary history is studied in the branch of biology called Phylogeny.
|
|
Ecology
|
The branch of biology that studies the interaction of organisims with one another and with the environment is called ecology.
|
|
Adaptation of a Cactus to Desert Environment:
|
they have thick, waxy covering to hold water. Their leaves are reduced to thin spike like plans that further prevent evaporation and keep predators from eating the plant.
|
|
Morphology
|
Biologist uses the term morphology to refer to the structure and form of an organisims or any of its parts.
|
|
Anatomy
|
Is a branch of morphology that deals with the internal structure and form of an organism or any of its parts.
|
|
How Living Organisims are Organized
|
All living organisms are organized on a molecular and cellular level.
|
|
Response
|
A response is a reaction to a stimulus
|
|
Reproduction
|
is not essential for the survival of an individual organism
|
|
Tissues
|
Tissues are composed of cells
|
|
Division
|
The orderly formation of a new cell from a parent cell is called division
|
|
Behavior
|
is a complex set of responses
|
|
Adaptation
|
The trait that gives an organism an advantage in a specific environment is called an adaptation
|
|
System
|
the highest level of organization within an organism is the system

|
|
Cells
|
All living things are composed of cells.
|
|
Evolution of Species
