BIO 110 Exam #1 (Tutorials #2-#6) Questions With
Complete Solutions
A defining feature of prokaryotes: Correct Answers lack of
membrane-bound nuclei
less subcellular specialization than eukaryotes
aerobic Correct Answers require oxygen
All species can be tracked back to the most recent common
ancestor how many years ago? Correct Answers 3.5 billion
amphipathic Correct Answers molecules that have the unique
ability to be both hydrophobic and hydrophilic
anaerobic Correct Answers any organism, environment, or
cellular process that lacks or does not require oxygen, and may
be poisoned by oxygen
binary fission Correct Answers cell division in which a
prokaryotic chromosome replicates and the mother cell pinches
in half to form two new daughter cells
bioremediation Correct Answers various species of bacteria for
the removal of toxins from the environment
capsule Correct Answers additional layer outside the cell wall
sticky substances made and secreted by a bacterium
, help bacteria adhere to surfaces or to each other and protection
carbon fixers Correct Answers Prokaryotes
Organisms that use this simple form of carbon (carbon dioxide)
chemoautotrophs Correct Answers obtaining energy from
inorganic chemicals
Conjugation Correct Answers two living prokaryotic cells
physically join with one another through a pilus
Covalent bonds Correct Answers bonds that involve the sharing
of electron pairs between two atoms
disaccharide Correct Answers sugar formed by a condensation
reaction between two monosaccharides
divide life into five kingdoms: Correct Answers Monera
(prokaryotes), Protista, Plantae, Fungi, and Animalia
Electronegativity Correct Answers a measure of an atom's
ability to attract electrons toward itself
endotoxins Correct Answers toxins that are present inside a
bacterial cell and are released when the cell disintegrates
Facultative anaerobes Correct Answers can alternate their
oxygen requirement. They can use oxygen if it is present, but
they can also function in an anaerobic environment
