BIOLOGY 121 EXAM 1 CHAPTERS 1-3
QUESTIONS AND ANSWERS 2024
Evolution - correct answers-Descent with modification: genetic change in a population
or species over generations: the heritable changes that have produced Earth's diversity
of organisms. Changes in DNA through time.
Biology - correct answers-The scientific study of life
List the 7 Properties of life that ALL living organisms share - correct answers-1.
Reproduction
2. Growth and Development
3. Energy Use
4. Order
5. Cells
6. Response to the Environment
7. Evolution
The levels of the biological organizations - correct answers-1. Biosphere
2. Ecosystem
3. Community
4. Population
5. Organism
6. Organ System and Organ
7. Tissue
8. Cell
9. Organelle
10. Molecule
Biosphere - correct answers-The global ecosystem: the entire portion of Earth inhabited
by life; all of life and where it lives at
Ecosystem - correct answers-All the organisms in a give area, along with the nonliving
(abiotic) factors with which they interact: a biological community and its physical
environment
Community - correct answers-All the organisms inhabiting and potentially interacting in
a particular area; an assemblage of populations of different species
, Population - correct answers-A group of interacting individuals belonging to one species
and living in the same geographic area at the same time.
Organisms - correct answers-An individual living thing, such as a bacterium, fungus,
protist, plant or animal.
Organ systems - correct answers-A group of organs that work together in performing
vital body functions
Organ - correct answers-A structure consisting of two or more tissues that coordinate to
perform specific functions
Tissue - correct answers-An integrated group of similar cells that performs a specific
function within a multicellular organism
Cell - correct answers-A basic unit of living matter separated from its environment by a
plasma membrane; the fundamental structural unit of life
Organelle - correct answers-A membrane-enclosed structure with a specialized function
within a eukaryotic cell
Molecule - correct answers-A group of two or more atoms held together by covalent
bonds
Reductionism - correct answers-Reduces complex systems to simpler components that
are more manageable to study
Emergent properties - correct answers-A trait that appears once the smaller parts are
made/combined.
For example the movement of amino acids into a protein. An amino acid, by itself,
cannot perform the tasks of an enzyme, but if you assemble the correct ones together in
the correct order, they become an enzyme.
Systems Biology - correct answers-The exploration of a biological system by analyzing
the interactions among its parts
Cell - correct answers-The smallest unit of organization that can perform all activities
required for life
Prokaryotic - correct answers-1. Bacteria and archaea
2. No nucleus
