BIO 107 EXAM 1 QUESTIONS AND
ANSWERS
Describe what is meant by the term 'Biology' - Correct Answers -The scientific study of
life
List and recognize examples of the characteristics displayed by living organisms -
Correct Answers -1) Energy processing; Humans ingest energy units and burn energy
units.
2) Order; Flowers have petals on the outside of the center. Cells have membranes
3) Evolutionary adaptation; Seahorse adapts to be able to camouflage in its
environment
4) Growth and development; Oak tree starts from acorn, cells grow by division.
5) Regulation; Humans maintain homeostasis through sweating.
6) Reproduction
7) Response to the environment
Structure and function - Correct Answers -how an organism works is based on
structure;
each major group of organisms has evolved structures that make particular functions
possible;
red panda has thumb for grabbing trees?
Transfer and transformation of energy and matter - Correct Answers -energy/matter can
move from one form to another;
* matter = takes up space, has mass, made of elements and chemicals
* energy = has no mass
plants take in light energy and convert it into sugar using chloroplast;
all matter on this planet was here when the earth was formed, with the exception of
meteors that hit our planet
Interactions within & between systems - Correct Answers -systems can interact with one
another;
organ systems interact with each other;
Compare methods for categorizing living organisms according to the three Domains of
Life: Archaea, Bacteria, and Eukarya; Given a description of an organism, place it in its
appropriate domain - Correct Answers -Archaea and bacteria = prokaryotes;
, microscopic organisms with relatively simple cells; no nucleus or membrane bound true
organelles
Eukaryotes = organisms with more complex cells; protists; have nucleus and membrane
bound organelles; Kingdom Plantae; Kingdom Animalia; Kingdom Fungi
Describe the levels of biological organization from molecule to the biosphere - Correct
Answers -atoms
molecules
organelles
cells
tissues
organs
organ systems
individuals of a species is called a population
community
- ALL living things in a geographic region that interact with each other
ecosystem
- living and NON living things included
Evolution - Correct Answers -applies to every single biological organism; occurs through
the process of natural selection; environment selects traits = adaptation
Darwins Theory of Evolution
Unity and Diversity - Correct Answers -birds have shared characteristics as well as
evolved characteristics;
phylogenic tree - common ancestors diverge from one another;
all forms of life are unified, share the 7 common properties of life, are made of cells, use
DNA as the genetic material
Flow of information - Correct Answers -how information is structured, stored, and
passed;
* Organisms detect and respond to stimuli
* glucose enters blood stream after consuming food
* body needs to regulate blood glucose
* pancreatic cell releases insulin
* insulin binding stimulates body cells to take up glucose
* normal blood glucose level removes signal, insulin release stops
Emergent properties - Correct Answers -New properties that arise with each step
upward in the hierarchy of life, owing to the arrangement and interactions of parts as
complexity increases;
* new properties that emerge when moving up the hierarchy of organization due to the
interaction of component parts
* can be between a living and non living thing in an environment
