BIOLOGY AND SYSTEMS MODULE 1
STUDY GUIDE MANESS Q&A
Which technology has been used to successfully deactivate specific human genes,
modify yeasts for biofuel production, and modify agricultural crop? - ANSWER-
CRISPR/Cas9
bread mold - ANSWER-Fungi
prokaryotes - ANSWER-bacteria
Suppose a particular protein is produced in excess of the cellʼs needs. What kind of
mechanism will intervene to stop production? - ANSWER-homeostatic
Which cells do not have a nucleus or other membrane-enclosed organelles? -
ANSWER-prokaryotic cells
Which organizational unit includes the fewest species of organisms? - ANSWER-
population
Which statement best describes autotrophic organisms? - ANSWER-Autotrophs
synthesize macromolecules from CO2, water, and energy.
All members of the same species occupying the same area at the same time
constitute a(n): - ANSWER-population
Using the Linnaean system of nomenclature, corn is named Zea mays. What is the
specific epithet in this name? - ANSWER-mays
What is a distinct characteristic of asexual reproduction? - ANSWER-a cell splitting
into identical halves
Which scenario best describes a double-blind study? - ANSWER-Neither the
investigator nor the subjects know who is in the experimental or control groups.
What is the purpose of the cilia and flagella of cells? - ANSWER-They provide
movement for the cell.
What is a branching diagram that depicts the relationships among organisms based
on shared characteristics? - ANSWER-cladogram
Which cells do not have a nucleus or other membrane-enclosed organelles? -
ANSWER-prokaryotic cells
Which is a benefit of sexual reproduction over asexual reproduction? - ANSWER-
The interaction of the genes from both parents allows genetic variation.
