BSC 105 Exam 1 Question and
answers verified to pass 2025/2026
Biology - correct answer ✔study of life and environment
What is life? - correct answer ✔organization of cells, consumes energy and performs metabolism,
reproduces, grows, develops, responds to environment, and undergoes evolution
What is the hierarchy of organization from biggest to smallest? - correct answer ✔-Biosphere
-Ecosystem
-Community
-Population
-Species
-Organism
-Organ System
-Organ
-Tissue
-Cell
-Molecule
-Atom
Entropy - correct answer ✔measurement of randomness of a system
What is the most entropic? - correct answer ✔Heat
Metabolism - correct answer ✔sum of all chemical reactions inside a cell or organism
,All life is bound by what? - correct answer ✔Law of Thermodynamics
Thermodynamics - correct answer ✔always loses energy, can not create more energy
Photosynthesis - correct answer ✔converts sunlight energy and waste into available food and energy
for the organism and is the primary source of energy
Carbon fixation - correct answer ✔turning waste into usable compounds
Nitrogen Fixation - correct answer ✔the bacteria form of carbon fixation
Homeostasis - correct answer ✔monitoring and maintaining an internal and external environment that
is accomplished using negative feedback
Set point - correct answer ✔given body parameter at the ideal value for life
What is negative feedbacks job within set point? - correct answer ✔decreases the difference between
a parameters current value and set point
Receptor - correct answer ✔monitors the parameter, reports to integrator
Integrator - correct answer ✔compares receptors information to set point, signals effector
Effector - correct answer ✔activated by integrator to bring parameter closer to set point
, Evolution - correct answer ✔organisms pass on genes to their offspring which changes the overall
frequency of genes and allows a population to adapt to its environment
Systemics - correct answer ✔application of taxonomy
Dad Says Kings Play Cards on Fat Green Stools - correct answer ✔Domain
Supergroup
Kingdom
Phylum
Class
Order
Family
Genus
Species
Domains - correct answer ✔Bacteria, Archaea, Eukarya
Bacteria - correct answer ✔contains one kingdom, no supergroups, prokaryotes "before the kernel",
unicellular, unique cell wall
Archaea - correct answer ✔prokaryotes, no supergroups, "before the kernel", unicellular, unique
membrane cell wall
Eukarya - correct answer ✔membrane-bound, nucleus, multiple supergroups and kingdoms, "true
kernel"
Kingdoms of eukarya - correct answer ✔Animalia, Plantae, Fungi, Protista
