BIOD 101 UPDATED EVALUATION TEST QUESTIONS AND
ANSWERS GUARANTEE A+
✔✔What is an adaptation? What characteristic of life would an adaptation fall into? -
✔✔adaption is a change or process that allows an organism based to become better
suited for its environment
-Responsiveness to the environment
✔✔Compare and contrast sexual and asexual reproduction. - ✔✔Sexual reproduction
involves the fusion of two gametes (one from each parent) that will unite and grow into a
new offspring.
-Asexual reproduction, in contrast, gives rise to new offspring from a single organism.
✔✔A group of one particular species living within defined boundaries of a community
best describes a(n): - ✔✔population
✔✔A system of living and non-living things in a region best describes a(n): -
✔✔ecosystem
✔✔What are the 3 domains that comprise the Linnaean Classification system? - ✔✔(1)
Archaea, (2) Eubacteria, and (3) Eukarya
✔✔What is the purpose of a phylogenic tree? - ✔✔A visual representation that shows
the relationships between different organisms and their evolutionary history
✔✔True or False: Extremophiles are a small sub-set of the Archaea domain that live in
extreme environments. - ✔✔true
✔✔Bacteria that neither benefits from nor harms its host and are often part of the
human flora are considered: - ✔✔commensal
✔✔Bacteria that cause illness are considered: - ✔✔pathogenic
✔✔Describe what an exotoxin is and give an example. - ✔✔An exotoxin is a toxic
substance that is secreted by bacteria into the surrounding environment
Cholera
✔✔Describe what an endotoxin is and give an example. - ✔✔A n endotoxin is a toxic
component of the outer membrane of a bacteria. The endotoxins are released when the
bacteria dies
, salmonella
✔✔Describe what a symbiotic relationship looks like between two organisms. - ✔✔A
long term relationship between two different organisms In which one or both organisms
benefit from the paired interaction
✔✔What are the 4 main Eukaryote Kingdoms? - ✔✔(1) Fungi, (2) Protista, (3) Plantae,
and (4) Animalia
✔✔Describe the process of binary fission and state whether it is a form of sexual or
asexual reproduction. - ✔✔Binary fission is an asexual form of reproduction. Binary
fission occurs when one cell splits in half to form two identical cells.
✔✔Compare and contrast 3 types of symmetry found in animal body plans. - ✔✔-Radial
Symmetry: symmetry around a center axis
-Bilateral Symmetry: when a line could split the body into two equal sides
-Spherical Symmetry: any cut through the center results two equal halves
✔✔Autotrophs are considered "primary producers". What does this mean? - ✔✔Primary
Producers support all other trophic levels by recycling organic matter from the
environment
✔✔Herbivores are considered "primary consumers". What does this mean? -
✔✔Primary consumers eat primary producers
✔✔You are considering a model system for research purposes. What are 6 guidelines
you should consider for this system? - ✔✔(1) Easy to maintain, (2) Physical size should
be convenient, (3) Inexpensive, (4) Short life cycles, (5) Can be genetically manipulated,
and (6) Can be used to deliver economically important results.
✔✔Individual living members of a population best describes a(n): - ✔✔organism
✔✔True or False. If false, explain why it is false.
The rRNA found in cells of the archaea domain would be identical to those found in the
eubacteria domain. - ✔✔False
-The rRNA found in cells of archaea domain are different than those found in the
eubacteria domain
✔✔________ plants lack the formation of tubes to transport water and nutrients. -
✔✔asvascular
✔✔Malaria is a result of plasmodium which are found in which of the following
Eukaryotic kingdoms? - ✔✔protista
