Chapter 1 - Introduction to HumanBiology
Name and define all of the properties of life. - correct answer ✔✔Cellular organization
+All living things are comprised of at least one cell
Metabolism
+All living things process energy which is used to power other processes - making ATP
Homeostasis - "steady-state"
+All living things maintain relatively stable internal environments to optimize conditions for metabolism
and other processes
Growth and reproduction
+All organisms have the capacity for growth and reproduction
Heredity
+All organisms pass genetic information to future generations from parents to offspring
State the hierarchy of life, starting at the atomic level and going up through the ecosystem. - correct
answer ✔✔Atoms
Molecules
Macromolecules
Organelles
Cells
Tissues
Organs
Systems
Organisms
Populations
Communities
Ecosystems
, *Biomes
*Biospheres
What are the five biological themes that the study of life is organized around? Define each. - correct
answer ✔✔*Flow of Energy: All living things require energy Energy is defined as ATP. ATP = Adenosine
Tri-Phosphate
*Metabolism
Term that is used to describe all chemical reactions involved in maintaining the living state of the cells
and the organism
Anabolism = The building of molecules using energy
Catabolism = The breakdown of molecules to obtain energy
*Cooperation
As energy and other resources are limiting, many organisms have evolved cooperation as a means of
survival
Symbiosis describes when two species live in direct contact
Mutualism = both species benefit
Commensalism = one species benefits, one is unaffected
Parasitism = one species benefits, one is harmed
*Structure Determines Function
Evolution favors structures that function in an adaptive manner
Many structures are specialized for a particular function
The convergence of structure and function occurs at levels of the organizational hierarchy
*Homeostasis
Homeostasis is a physiological condition of "steady-state"
The internal environment of organisms is relatively stable
Organisms act to control their internal environments so that the complex processes of metabolism
functions efficiently
